hi- does anyone know how many calories are burned in each of the p90x exercises? i believe in the handbook it said 600 calories per exercise, but i wonder if anyone knows if this is factual? thanks!

    The most accurate way is to go by your heart rate.
    If you just want an estimate (i just do it the old fashioned way) I get a timer for 6 seconds and everytime I go to get a drink or if there's a break (in Insanity there are) I check my heart rate (you times whatever that number was by 10).
    They have a bunch of calculator/formulas to figuring it out from there.
    Hope that helps!

    Here are the formulas:
    Step 3
    For males, estimate the calories that you burned during your exercise session. This is given by the equation C = (0.6309 x H + 0.09036 x W + 0.2017 x A -- 55.0969) x T / 4.184. C is the number of calories that you burned, H is your average heart rate, W is your weight, A is your age and T is the length of your exercise session in minutes.
    Step 4
    For females, derive the calories that you burned. This is given by the equation C = (0.4472 x H -- 0.05741 x W + 0.074 x A -- 20.4022) x T / 4.184. Assume that you're a 28-year-old female weighing 146 pounds. Your average heart rate during an exercise session that lasted 36 minutes was 138 bpm. You burned C = (0.4472 x 138 -- 0.05741 x 146 + 0.074 x 28 -- 20.4022) x 36 / 4.184 = 301 calories.

    It depends on the person. I'm starting my 5th week of p90x and I haven't burned more than 400 cals yet. Others have burned up to 800..
