CrossFit WOD Calculator: Calories, Intensity, Scaling

A typical 15-to-25 minute high-intensity CrossFit WOD burns between 150 and 350 active calories, depending on athlete body weight, gender, and pacing intensity (averaging 10 to 18 calories per minute). Furthermore, high-intensity functional training triggers excess post-exercise oxygen consumption (EPOC), elevating metabolic rate for hours post-workout.

AMRAP stands for 'As Many Rounds (and Reps) As Possible'. Athletes are given a fixed time cap (such as 12, 15, or 20 minutes) to cycle through a sequence of exercises as many times as possible before the clock expires.

EMOM stands for 'Every Minute On the Minute'. At the start of every 60-second interval, you perform a designated number of repetitions of an exercise. Any remaining time in that minute is your rest period before the next minute begins.

Rx stands for 'as prescribed' (from medical prescription notation). It means completing the workout with the exact prescribed barbell weights, box heights, and movement standards without any modifications or reductions.

Scale to preserve the intended intensity: reduce barbell weight to 60%-80% of Rx, reduce rep volume if the movement is technically demanding, and substitute gymnastics (e.g., jumping pull-ups, knee raises, or box push-ups). You should be able to move continuously with safe, consistent technique.

Relative intensity compares the external load on the barbell or implement against your body weight, scaled by your fitness level coefficient. A 60 kg clean and jerk represents a vastly higher relative neuromuscular load for a 65 kg athlete than for a 95 kg athlete.

Most coaches recommend 3 to 5 training days per week. Classic CrossFit schedules follow either 3 days on / 1 day off or 5 days on / 2 days off (weekends). Adequate sleep, nutrition, and at least 1-2 active recovery days are vital to prevent overtraining and joint inflammation.

No. All caloric, MET, and intensity estimates are intended for athletic planning and general guidance. Always consult a physician before undertaking high-intensity exercise, especially if you have cardiovascular or orthopedic conditions.
