How much is too much exertion before it turns negative on your body IE: cortisol? I've been throwing in some 3 hour workouts and pounding pretty hard, but i'm kinda concerned of hearing that lengthy workouts can produce cortisol in your body to kill the pain of prolonged work. When I workout do switch it up for the 3 hours something like this.
30 minutes of heavy bag kicks
10 min jump rope
2 hours of weights
20 min basketball or soccer
Should I be splitting these 3 hours up 1-1-1? I'm already guessing some of you have been doing this. My other guess would be that it would be more benificial for my metabolism spiking it in a split rather than all at once.
