I have a question for endurance....I'm 6"2 230 ,and natural endomorph, about 18 to 20% BF....I've run into an endurance problem. I'm currently training for something special in the military, and have to be able to do over 100 sit ups,push up, and flutter kicks. Now I can do all 100 but can't seem to do them non stop in the 2min time frame, I usually give out around 60. I'm trying to do the all natural thing but am having a hard time any suggestions.
