cool, but there's not much guess work in bodyweight exercises imo.. just have fun and rep everything out, tons of sets until you're toast.
I don't know I seem to push my self too hard. Subconsciously, whenever I do pushups or pullups, if i dont go to ultimate failure, I feel sort of "guilty" afterwards. When I go to failure, I have to do it for ALL sets, and afterwards, I just feel fried. Eventually, I actually "fear" the specific exercise. I am too much of an all or nothing guy.
Its WACK and i know that is acting like a pussy. I just like these because it gives me mental piece after i do pushups
