CrossFit WOD Calculator

Calculate calories burned during CrossFit WODs. Estimate energy expenditure for AMRAP, For Time, and EMOM workouts based on intensity and duration.

Estimate calories burned during CrossFit WODs based on workout type and intensity.

About This Calculator

The CrossFit WOD Calculator estimates your calorie expenditure during CrossFit Workouts of the Day. CrossFit's high-intensity functional movements create significant metabolic demand, and this tool helps you understand the energy cost of your training based on workout type, duration, and intensity level.

CrossFit workouts are known for their variety and intensity. AMRAP (As Many Reps As Possible), For Time, and EMOM (Every Minute On the Minute) formats each create different metabolic responses. Understanding these differences helps you plan nutrition, recovery, and training periodization effectively.

Calorie Estimation Formula

Calories = (Base MET + Intensity Adjustment) × Weight in kg × Duration in hours

CrossFit typically ranges from 8-15 METs depending on intensity, with competitive workouts reaching even higher.

Practical Example

An 80 kg athlete doing a 20-minute AMRAP at intensity 8/10: Calories = approximately 300-400 kcal. A high-intensity "Fran" (sub-3 minutes) burns 50-75 kcal but creates significant EPOC (afterburn).

Tips for CrossFit Training

  • Scale workouts appropriately—intensity matters more than Rx weight for fitness gains
  • EPOC (excess post-exercise oxygen consumption) adds 10-15% more calorie burn after intense WODs
  • Fuel properly: 1-2g carbs per kg bodyweight before intense sessions
  • Recovery is training—rest days are essential for adaptation

Frequently Asked Questions

How are CrossFit WOD calories calculated?

Calories = (Base MET + Intensity Adjustment) × Weight kg × Hours. CrossFit typically 8-15 METs. Add 10-15% for EPOC afterburn. For Time workouts slightly higher than EMOM.

How many calories does a 20 minute CrossFit WOD burn?

300-500 calories for most people at high intensity. An 80kg athlete at 8/10 intensity: ~350 cal + 40 cal EPOC. Varies by workout type and individual effort.

What is EPOC in CrossFit?

Excess Post-exercise Oxygen Consumption—continued calorie burn after workout ends. High-intensity WODs create 10-15% additional burn for hours after. Also called 'afterburn effect'.
