CrossFit Calorie Science: How WOD Type Drives Metabolic Output
CrossFit produces some of the highest calorie burns per hour of any structured exercise format, with Competition and Hero WODs reaching MET values (12.0 to 13.0) that rival competitive rowing and sprint cycling. The variation across WOD types is wide enough that the calorie difference between a strength-focused barbell day (MET 6.0) and a max-effort competition WOD (MET 13.0) exceeds 100% at the same body weight and session duration. At 175 pounds (79.4 kg) for a 60-minute class: a strength WOD produces approximately 476 session calories, while a competition-style WOD produces approximately 1,032 session calories, more than double the calorie burn from choosing a different workout format on the same day at the same box.
The reason CrossFit produces such high MET values is the deliberate combination of cardiovascular demand (running, rowing, assault bike, jump rope) with resistance training (barbell movements, gymnastics, kettlebells) in formats that minimize rest and maximize sustained effort. During a Metcon or AMRAP, the cardiovascular system operates at 80 to 95% of maximum heart rate for most of the working interval, while simultaneously the muscular system performs compound movements recruiting the quadriceps, hamstrings, glutes, shoulders, and back under load. The combined demand of cardiovascular and muscular effort at this intensity exceeds what either modality produces in isolation, explaining why CrossFit consistently ranks among the highest-MET activities in the Compendium of Physical Activities for the duration of the working interval.
EPOC: Why CrossFit Keeps Burning Calories for Hours After the WOD
Excess Post-Exercise Oxygen Consumption (EPOC), often called the afterburn effect, is the elevated calorie burn that continues after exercise ends as the body returns to its resting state, replenishes energy stores, repairs muscle tissue, and processes metabolic byproducts of intense exercise. CrossFit produces among the highest EPOC values of any exercise format because it combines two EPOC-generating stimuli simultaneously: high-intensity cardiovascular effort that depletes glycogen and creates oxygen debt, and heavy resistance loading that causes muscle microtrauma requiring extended repair energy. For a vigorous Metcon WOD, research estimates EPOC at 12 to 15% of session calorie burn, persisting for 12 to 38 hours post-workout depending on WOD intensity and individual fitness level.
For Hero WODs like Murph (1-mile run, 100 pull-ups, 200 push-ups, 300 air squats, 1-mile run), the combination of extreme volume, cardiovascular demand, and muscular endurance stimulus creates EPOC values at the higher end of the documented range. Skill and technique sessions produce minimal EPOC (approximately 5%) because the intensity stimulus is insufficient to create significant oxygen debt or muscle damage requiring prolonged recovery energy expenditure.

Three Expert Training Tips for US CrossFit Athletes Tracking Calorie Burn
01
Count EPOC in Your Weekly Calorie Budget: CrossFit Afterburn Is Real and Meaningful
The EPOC from vigorous CrossFit WODs is not a marketing claim but a documented physiological response supported by research from the Journal of Strength and Conditioning Research, the International Journal of Sports Physiology and Performance, and multiple university exercise physiology programs. For a 185-pound athlete doing four Metcon WODs per week at approximately 924 session calories each, the EPOC adds approximately 480 additional calories per week to total energy expenditure, approximately 0.55 additional pounds of theoretical fat loss per month beyond what the session calories alone account for. Over a 12-week training block, cumulative EPOC from four weekly Metcon sessions contributes approximately 5,760 calories (approximately 1.65 pounds of additional fat loss) that a calorie counter tracking only session burn would miss entirely. The practical implication is that athletes tracking their CrossFit calorie expenditure should add the EPOC estimate from this calculator to their total weekly burn figure rather than counting only session calories, because the afterburn represents a real and sustained metabolic elevation. The EPOC values used in this calculator (5% for skill work to 16% for competition WODs) are conservative estimates derived from published EPOC research on high-intensity mixed-modal exercise; individual responses vary based on fitness level, training history, and WOD-specific movement patterns.
02
Mix WOD Types Across the Week to Maximize Total Calorie Burn and Prevent Overtraining
A training week that varies WOD types strategically produces higher total calorie burn with lower overtraining risk than attending the same high-intensity format every day. Consecutive days of maximum-intensity Metcon or competition-style WODs (MET 11.0 to 13.0) deplete glycogen stores, accumulate muscle damage, and suppress the immune system in ways that impair performance and force involuntary recovery, reducing actual calorie burn on subsequent sessions. A well-programmed CrossFit week that most US box coaches recommend includes two to three Metcon or AMRAP sessions for maximum calorie and conditioning stimulus, one to two strength WODs for progressive muscle development, and one skill or EMOM session for movement quality and nervous system recovery. At 175 pounds for a 5-day training week using this structure (3 Metcon + 1 Strength + 1 Skill): estimated weekly session calories are approximately 2,958 calories, plus EPOC of approximately 385 calories, for a total of approximately 3,343 weekly exercise calories. A five-day week of all Metcon WODs would theoretically produce approximately 4,620 session calories, but accumulated fatigue from consecutive max-effort days reduces actual exercise output and performance within 3 to 5 days for most athletes, making the mixed approach both more sustainable and often more effective for long-term calorie burn.
03
Use Benchmark WOD Times to Track Fitness Progress Independently of Calorie Tracking
The four benchmark WODs referenced in this calculator (Fran, Cindy, Grace, Murph) serve a specific purpose in CrossFit programming that calorie tracking does not capture: they measure fitness progress across time by comparing performance on identical standardized workouts at different points in a training cycle. A Fran time improvement from 9 minutes to 6 minutes over 12 weeks represents a 33% performance improvement and a meaningful increase in power output (calories burned per unit time), a fitness gain that shows up in improved WOD performance but may not appear clearly in session calorie numbers if the athlete is also losing weight during the cycle. Because CrossFit calorie burn depends on both body weight and MET, a 175-pound athlete who improves fitness and drops to 165 pounds may burn similar total session calories as before despite dramatically improved cardiovascular and muscular performance. For this reason, most US CrossFit coaches recommend tracking both calorie burn (to understand total energy expenditure) and benchmark WOD times (to measure fitness progress), using the two metrics as complementary tools. CrossFit maintains a library of benchmark WODs and Hero WODs with RX standards at crossfit.com, and most US box management software (SugarWOD, Wodify, Beyond the Whiteboard) allows athletes to log and track benchmark WOD times across their training history.
What Do US CrossFit Athletes and Box Coaches Ask About WOD Calorie Burn?
A 1-hour CrossFit class burns approximately 400 to 1,000 calories for most US adult athletes, with the wide range reflecting the dramatic difference in calorie burn between WOD types and body weights. At 175 pounds (79.4 kg): a strength WOD class burns approximately 476 session calories, a standard Metcon approximately 874 session calories, a Hero WOD approximately 953 session calories, and a competition-style Open WOD approximately 1,032 session calories. At 145 pounds (65.8 kg), these figures drop to approximately 395, 725, 790, and 856 session calories respectively. Adding EPOC increases these totals by 7% for strength days and up to 16% for competition WODs. Most fitness trackers estimate CrossFit calorie burn at 500 to 800 calories per hour for average adult body weights, which aligns with the EMOM-to-Metcon range (MET 8.0 to 11.0) that represents the most common US box class format. The estimates from heart rate-based fitness trackers can be inaccurate for CrossFit because the mixed cardiovascular and resistance training format produces heart rate responses that do not map cleanly to the metabolic rate algorithms calibrated for steady-state cardio. For athletes with a WHOOP, Polar H10, or Garmin HRM chest strap, heart rate data is more accurate than wrist-based optical trackers for CrossFit’s variable-intensity movements, but MET-based estimates like those in this calculator provide a useful benchmark for comparison.
Murph (1-mile run, 100 pull-ups, 200 push-ups, 300 air squats, 1-mile run) burns approximately 700 to 1,300 calories for most US adults completing it, with total calorie burn depending on body weight, completion time, weighted vest use, and individual fitness level. At 175 pounds (79.4 kg) with a 50-minute finish time at Hero WOD intensity (MET 12.0): approximately 793 session calories plus approximately 119 EPOC calories equals approximately 912 total 24-hour calories. At 175 pounds with a 40-minute finish: approximately 635 session calories plus approximately 95 EPOC equals approximately 730 total calories. With a 20-pound weighted vest (adding approximately 11% to calorie burn through increased weight): approximately 883 session calories (50-minute finish) plus approximately 132 EPOC equals approximately 1,015 total calories. The two 1-mile runs contribute the highest MET moments of Murph (running at roughly MET 9.0 to 11.0), while the 100-200-300 bodyweight movement block produces sustained cardiovascular and muscular demand at an average MET that most exercise physiologists estimate in the 11.0 to 13.0 range for athletes completing it in 40 to 60 minutes. CrossFit officially programs Murph as the Memorial Day Hero WOD each year; many US boxes offer special events with scaled (non-weighted) and RX (20-pound vest) divisions, with completion times tracked individually by most CrossFit programming software platforms.
CrossFit is one of the most effective exercise formats for weight loss due to its combination of high session calorie burn, meaningful EPOC contribution, muscle development from compound barbell and gymnastics movements, and the social accountability structure of group training at a box. A meta-analysis of CrossFit-related research published in Sports Medicine in 2021 found that CrossFit participation consistently produced significant reductions in body fat percentage and improvements in VO2max, muscular strength, and body composition across study populations, with improvements typically exceeding those of traditional gym training programs matched for training frequency and duration. The session calorie burn from four weekly Metcon WODs at 175 pounds produces approximately 3,500 session calories per week before EPOC, which is equivalent to approximately 1 pound of theoretical fat loss per week from exercise alone at constant dietary intake. With EPOC included (approximately 13% for Metcon), total weekly energy expenditure from four WODs reaches approximately 3,950 calories, supporting approximately 1.1 pounds of fat loss per week from CrossFit alone. Dietary awareness is still required for significant fat loss; CrossFit athletes who eat without tracking intake often find that increased appetite from training partially compensates for the calorie burn. The combination of CrossFit training with moderate dietary tracking produces the most consistent fat loss outcomes for US CrossFit athletes.
AMRAP stands for “as many rounds as possible,” a CrossFit and functional fitness WOD format where athletes complete a fixed set of exercises in sequence and repeat the circuit as many times as possible within a set time cap, typically 10 to 20 minutes. The continuous effort format of AMRAP with minimal prescribed rest keeps heart rate elevated throughout the working period, producing high average calorie burn per minute among CrossFit formats. AMRAP workouts use a MET of 10.0 in this calculator, reflecting the sustained cardiovascular demand of continuous-effort circuit training. At 175 pounds (79.4 kg): a 20-minute AMRAP burns approximately 264 session calories plus approximately 32 EPOC calories for approximately 296 total calories. A 30-minute AMRAP burns approximately 397 session plus approximately 48 EPOC for approximately 445 total calories. Cindy (20-minute AMRAP: 5 pull-ups, 10 push-ups, 15 air squats) is the most commonly programmed benchmark AMRAP in US CrossFit boxes, with scores typically ranging from 10 to 25 completed rounds depending on athlete fitness level. The beauty of AMRAP from a calorie-tracking perspective is that the total time is fixed, making calorie estimation straightforward: the MET and body weight are consistent throughout the fixed duration, unlike for-time WODs where completion speed varies the duration and therefore the total calorie calculation.
Vigorous CrossFit WODs (Metcon, AMRAP, Hero WOD at MET 11.0 to 12.0) burn similar or greater calories per hour than running at moderate-to-fast paces, while strength WODs and EMOM sessions burn considerably fewer calories than running. Comparing calories at 175 pounds per 60 minutes: running at 6 mph (MET 9.8) burns approximately 778 calories; a Metcon WOD (MET 11.0) burns approximately 874 session calories; a Hero WOD (MET 12.0) burns approximately 953 session calories; running at 8 mph (MET 11.8) burns approximately 937 calories; a competition WOD (MET 13.0) burns approximately 1,032 calories. At the vigorous end, CrossFit WODs and fast running produce comparable per-hour calorie burn. CrossFit produces higher EPOC than steady-state running of equivalent duration, making the 24-hour energy expenditure comparison more favorable to CrossFit than the session calories alone suggest. Running has an advantage for consistent moderate-intensity calorie burn over long distances (60 to 120-minute runs at moderate pace), while CrossFit has an advantage for maximum calorie burn per unit time at high intensities, and for the muscle retention benefits that prevent the loss of lean mass sometimes associated with high-volume endurance training. Use our Running Calorie Calculator to compare your run and WOD calorie burns directly.
EMOM stands for “every minute on the minute,” a CrossFit format where athletes perform a prescribed number of repetitions at the start of each minute, then rest for the remainder of that minute until the next minute begins. The built-in rest structure of EMOM formats produces a lower average MET (8.0 in this calculator) than AMRAP or Metcon workouts, because each working interval is followed by recovery time proportional to how quickly the athlete completes the prescribed reps. A well-programmed EMOM keeps athletes working for approximately 30 to 45 seconds per minute (50-75% work-to-rest ratio), with the rest period ensuring quality of movement and preventing the technical breakdown that occurs in continuous-effort workouts at maximum intensity. At 175 pounds (79.4 kg): a 20-minute EMOM burns approximately 212 session calories plus approximately 19 EPOC calories for approximately 231 total calories. A 30-minute EMOM burns approximately 318 session plus approximately 29 EPOC for approximately 347 total calories. EMOM formats are popular at US boxes for skill development (Olympic lifting EMOMs, gymnastics skill EMOMs) and moderate-intensity conditioning work on recovery days, because the structured rest allows athletes to maintain technique and power output across all intervals.
CrossFit Open workouts, released over five weeks each spring through the CrossFit Games competition platform, typically burn 300 to 800 session calories per workout at most adult body weights, depending on the specific movements, time cap, and athlete performance level. Open workouts typically run 7 to 15 minutes for most athletes at prescribed or scaled loads, placing them in the shorter-duration competition WOD category despite their high intensity. Using the competition WOD MET of 13.0 at 175 pounds: a 10-minute Open workout produces approximately 172 session calories plus approximately 28 EPOC for approximately 200 total calories; a 15-minute Open workout produces approximately 258 session plus approximately 41 EPOC for approximately 299 total calories. Athletes who log scores on the Open leaderboard at games.crossfit.com typically have higher fitness levels that allow them to maintain MET 13.0 intensity more consistently throughout the time cap. For the annual 5-week CrossFit Open, completing five workouts at 10 to 15 minutes each contributes approximately 1,000 to 1,500 total calories (session plus EPOC) across the Open period, a meaningful contribution to weekly energy expenditure during competition month.
CrossFit is appropriate for beginners when introduced through a proper onboarding program at a quality CrossFit box with certified Level 2 (CF-L2) or higher coaches, with movement scaling applied consistently from the first class. Most US CrossFit affiliates offer a fundamentals or foundations course (typically 3 to 6 sessions) before new members join group classes, teaching the foundational movements (air squat, deadlift, press, clean, pull-up, push-up) with proper mechanics before adding load, intensity, or competitive scoring pressure. A 2018 systematic review in the British Journal of Sports Medicine analyzing CrossFit injury rates found that the incidence of injury per 1,000 training hours was comparable to Olympic weightlifting, gymnastics, and recreational running, with the shoulder, lower back, and knee being the most common injury sites. The high-calorie WOD types (AMRAP, Metcon, Hero WOD) are not appropriate for beginners in their full prescribed form; new athletes should expect to scale all WODs significantly for the first 3 to 6 months of training, which also means the calorie burn for beginners will be lower than the Metcon and competition MET values suggest until fitness and technique allow standard scaling to be used safely. CrossFit maintains a certified affiliate finder and coach credential database at crossfit.com.
Most CrossFit coaches and sports scientists recommend 3 to 5 WODs per week for optimal results for intermediate athletes, with beginners starting at 3 sessions per week and advanced athletes extending to 5 to 6 sessions with careful programming. The foundational CrossFit prescription from CrossFit HQ is three days on and one day off (3-on-1-off), which produces 5 to 6 training days per week in a monthly cycle, interspersed with regular rest days that allow full recovery between high-intensity sessions. For most US CrossFit athletes attending group classes at a box, 4 sessions per week represents the most common and effective frequency, producing approximately 3,500 to 4,500 total weekly calories (session plus EPOC) at average body weights and Metcon-level intensity, while allowing sufficient recovery for the muscular damage and energy system depletion that high-intensity WODs produce. Athletes who train more than 5 days per week without periodization commonly report declining performance, persistent soreness, disrupted sleep, and reduced motivation within 3 to 6 weeks, consistent with the signs of overtraining syndrome described by the American College of Sports Medicine. The most effective weekly structure for US CrossFit athletes seeking maximum calorie burn and fitness improvement is 3 to 4 high-intensity WODs (Metcon, AMRAP, or Hero WOD) combined with 1 to 2 lower-intensity sessions (Strength WOD or EMOM), a balance that maximizes training stimulus while allowing adequate recovery.
A Chipper WOD presents a long list of exercises completed sequentially for time, “chipping away” at a high total rep count across multiple movement categories. Unlike AMRAP (repeated circuits) or EMOM (time-structured intervals), a Chipper is performed for time with athletes progressing through each movement category until completion. The Chipper MET of 9.0 in this calculator reflects the moderate-to-high intensity maintained across the varied movement sequence, which includes periods of higher intensity (rowing, box jumps, burpees) and lower intensity (wall ball, thrusters at reduced weight, double-unders for skilled jumpers). A well-known benchmark Chipper is “The Seven” (7 rounds of 7 handstand push-ups, 7 thrusters at 135/95 lb, 7 knee-to-elbows, 7 deadlifts at 245/170 lb, 7 burpees, 7 kettlebell swings, 7 pull-ups), which typically takes 25 to 45 minutes for intermediate athletes. At 175 pounds for 35 minutes at Chipper MET 9.0: approximately 397 session calories plus approximately 40 EPOC for approximately 437 total calories. Chippers produce somewhat lower peak heart rates than AMRAP or Metcon workouts because the exercise variety includes recovery-pace movements between the highest-intensity exercises, but they produce higher total volume (total reps completed) than most other WOD formats, making them effective for muscular endurance development alongside meaningful calorie burn.
A CrossFit strength WOD burns approximately 55% fewer session calories than a Metcon WOD at the same duration and body weight, reflecting the fundamental difference between low-rep, high-rest barbell training and continuous-effort metabolic conditioning. At 175 pounds (79.4 kg) for a 60-minute class: a strength WOD (MET 6.0) burns approximately 476 session calories plus approximately 33 EPOC calories for approximately 510 total calories, while a Metcon (MET 11.0) burns approximately 874 session calories plus approximately 114 EPOC calories for approximately 988 total calories. The calorie difference reflects genuine differences in metabolic demand: during a 5×5 back squat session with 3-4 minutes of rest between sets, the athlete spends the majority of the class time resting at near-resting metabolic rate, with only the working sets (approximately 8-12 minutes of the 60-minute class) at high metabolic intensity. During a Metcon, the athlete maintains cardiovascular and muscular effort continuously for 10 to 20 minutes of the WOD itself, producing much higher average MET across the session. The muscle development from progressive overload barbell training increases resting metabolic rate over time and produces a different EPOC signature, contributing to long-term calorie burn advantages that do not show up in single-session estimates. Most US CrossFit programming coaches balance strength and Metcon days across the training week to develop both energy systems while managing recovery demands.
CrossFit and HIIT (high-intensity interval training) overlap significantly in calorie burn per session, but differ in movement complexity, equipment requirements, and the balance of cardiovascular versus resistance training stimulus. At equivalent intensities and durations, CrossFit Metcon and AMRAP WODs (MET 10.0 to 11.0) produce similar session calorie burns to vigorous HIIT protocols (MET 10.0 to 12.0 depending on exercise selection). The EPOC from both formats is also comparable at maximum effort (12 to 16% of session calories). The key structural difference is movement complexity: CrossFit incorporates Olympic lifting, gymnastic movements, and complex barbell exercises that develop strength, power, and skill alongside cardiovascular conditioning, while most HIIT programs use simpler movements that can be executed without instruction and produce cardiovascular stimulus without the same strength development. For pure calorie burn with no equipment access, a vigorous HIIT session may be slightly more accessible. Many US boutique fitness studios offer HIIT and CrossFit hybrid programming and the calorie burn difference between comparable sessions is minimal when WOD intensity is matched. Compare your session estimates directly with our HIIT Calorie Calculator.
Fitness trackers produce consistently inaccurate CrossFit calorie estimates, with published studies showing errors of 25% to 93% compared to indirect calorimetry reference measurements during high-intensity mixed-modal exercise. A 2021 study in the International Journal of Exercise Science tested five consumer trackers (Apple Watch, Fitbit, Garmin, Polar, and WHOOP) during CrossFit workouts and found that all five significantly underestimated calorie burn during resistance movement phases (barbell work, gymnastic movements) and overestimated during cardiovascular phases (rowing, running), producing net errors that were inconsistently bidirectional across individuals. The fundamental challenge for trackers during CrossFit is that wrist-based optical heart rate sensors struggle with wrist position changes during barbell exercises (front rack, overhead position), bouncing during double-unders and box jumps, and the variable blood flow from grip pressure during pull-ups and rowing, all of which cause heart rate reading errors that cascade into calorie estimate errors. Chest strap heart rate monitors (Polar H10, Garmin HRM-Pro) perform significantly better for CrossFit calorie tracking. For most US CrossFit athletes, the MET-based calculation method used in this calculator produces estimates that are more consistent with indirect calorimetry standards than consumer wrist tracker algorithms for CrossFit’s variable-intensity movements, and serves as a useful cross-reference when tracker estimates seem unexpectedly high or low for a given WOD.
CrossFit calorie estimates from this calculator provide a useful starting point for weight loss meal planning, but should be combined with your Total Daily Energy Expenditure (TDEE) rather than used in isolation. Your TDEE represents total daily calorie burn including basal metabolic rate, non-exercise activity, and exercise, and is the figure from which a calorie deficit should be calculated for fat loss. A 175-pound CrossFit athlete attending four 60-minute Metcon WODs per week who has an active daily lifestyle might have a TDEE of approximately 3,200 to 3,600 calories per day. Creating a 500-calorie daily deficit from this TDEE produces approximately 1 pound of fat loss per week, while the EPOC from CrossFit adds an additional 0.1 to 0.2 pounds per month of calorie burn. Use our TDEE Calculator to determine your full daily energy expenditure, then use these CrossFit estimates to understand what portion of your TDEE comes from your training sessions. Many US registered dietitians who work with CrossFit athletes (findable through the Academy of Nutrition and Dietetics at eatright.org using the Sports Dietetics specialty filter) recommend building meal plans around WOD performance and recovery needs first, with fat loss as a secondary outcome of appropriate total calorie and macronutrient targets rather than aggressive cuts that impair training performance.
The most useful US resources for CrossFit training, development, and evidence-based athletic support include: CrossFit at crossfit.com, the organization that developed and maintains the CrossFit methodology, offers free Level 1 training guide downloads, the official WOD posting, Open workout information, and a certified affiliate and coach finder for locating quality boxes and certified coaches throughout the US. The CrossFit Journal at journal.crossfit.com publishes training articles, movement standards, programming theory, and athlete profiles from the CrossFit community. Beyond the Whiteboard at beyondthewhiteboard.com and SugarWOD at sugarwod.com are the most widely used CrossFit performance tracking apps in US boxes, enabling athletes to log WOD scores, benchmark times, strength PRs, and training history. The National Strength and Conditioning Association at nsca.com provides the CSCS (Certified Strength and Conditioning Specialist) credential relevant to CrossFit coaches seeking evidence-based programming credentials. The American College of Sports Medicine at acsm.org publishes position papers on high-intensity training, EPOC, and exercise program design that provide scientific grounding for CrossFit methodology. PubMed at pubmed.ncbi.nlm.nih.gov provides access to peer-reviewed CrossFit research with searches for “CrossFit injury,” “CrossFit body composition,” and “high intensity functional training” returning substantive research literature published since 2010.
CrossFit nutrition for performance and body composition is addressed officially by CrossFit HQ through the Zone Diet approach (macronutrient proportions of 40% carbohydrate, 30% protein, 30% fat measured in blocks) and the foundational “eat meat and vegetables, nuts and seeds, some fruit, little starch, no sugar” prescription communicated in CrossFit’s Level 1 training materials. Many US CrossFit athletes use flexible macronutrient tracking instead of rigid zone block counting, targeting protein at 0.8 to 1.0 grams per pound of body weight (156 to 175 grams per day for a 175-pound athlete), carbohydrates sufficient to replenish glycogen between training sessions (200 to 300 grams per day for athletes training 4 to 5 WODs weekly), and fat providing the remaining calorie balance. Pre-WOD nutrition should prioritize carbohydrate availability: consuming 30 to 60 grams of carbohydrate (oatmeal, rice, banana, sweet potato) 60 to 90 minutes before a Metcon or AMRAP WOD ensures glycogen availability for the high-intensity glycolytic energy demand these WOD formats create. Post-WOD recovery nutrition should prioritize protein (25 to 40 grams within 30 to 60 minutes of training) for muscle protein synthesis stimulus, combined with carbohydrates (40 to 80 grams) for glycogen replenishment, particularly important on back-to-back training days. The Precision Nutrition coaching platform at precisionnutrition.com, the CrossFit Level 1 nutrition chapter at crossfit.com, and the US dietary guidelines for physically active adults at dietaryguidelines.gov provide comprehensive nutrition frameworks appropriate for CrossFit athletes at varying training intensities.

MET values are research-based estimates calibrated to CrossFit’s high-intensity mixed-modal exercise formats. Strength WOD MET 6.0 and Skill MET 4.5 reflect lower-intensity phases typical of technique and barbell sessions. Metcon MET 11.0, Hero WOD MET 12.0, and Competition MET 13.0 reflect sustained high-intensity effort documented in exercise physiology research on CrossFit and functional fitness. EPOC percentages (5-16%) are conservative estimates from published post-exercise oxygen consumption research. Net calories subtract resting MET (1.0). Fat loss projection uses 3,500 cal/lb. Individual results vary by movement efficiency, scaling, rest periods, and individual metabolic rate.
CrossFit carries inherent risk of injury. Beginners should complete a fundamentals course with certified coaches before high-intensity WODs. US resources: CrossFit.com, NSCA, ACSM, CDC Physical Activity.
