I'd like to add some sprinting into my workouts, in place of steady state running on a treadmill. The problem I run into is this, and if others have, please chime in:
I KNOW how much running at say 7.0 mph will burn for 20 minutes, 30 minutes, etc. I know how my body will react to it. With sprinting I have NO clue what the equivalent for fat loss is to say running 6 or 7 miles per hour for 30 minutes. It's not something I want to experiment with because I don't want to under-do it, and fuck up a cut, or over-do it and lose a shit ton of muscle. Anyone else feel this way?
