P90X is a 12-DVD, 90-day extreme home fitness program featuring workouts for specific body parts, interval-style cardio and martial arts-inspired workouts, and stretch and yoga routines, says AceFitness.com. The Plyometrics workout is one of the most intense routines in the program and will burn a large amount of calories.
Body mass index, BMI, is a measure of body fat based on height and weight that applies to adult men and women, says the National Heart Lung and Blood Institute. Your Body Mass Index, BMI, is an important factor to accurately calculate your calories burned during P90X plyometrics.
Heat rate is another important factor to track calories burned when performing Plyometrics X. Calculate your heart rate by using a heart rate monitor or placing your index finger on your wrist or neck, below the jaw line, and count your beats for 10 seconds. Multiply that number by six to figure out your heart rate per minute. Use a calories burned calculator to enter your heart rate and calculate your total calories burned during exercise.
On average, 480 calories are burned per hour when performing plyometric exercises. To accurately calculate your calories burned, take into consideration your BMI, intensity and heart rate.
