logging Power 90 and p90x

wiseg2

How would you log power 90 and p90x in your exercise log? I don't own a heart rate monitor to calculate the calories burned. Thanks in advance for your help.

The very best solution would be a heart rate monitor. You can find them as cheap as $20. Nothing else will come close as far as accuracy. That way you know you are counting only what you are earning. I use a heart rate monitor every workout, and see sizable fluctuations on the same workout on different days depending on how hard I've pushed myself. It's the best investment I've made workout wise.
