Can anybody help settle a disagreement between myself and my roommate? It's regarding calisthenics - specifically push ups and sit ups. He says that a person would be better off to not do them every day because it doesn't allow the muscles time to repair themselves. He thinks every other day is just as good if not better. While I will agree that his theory holds true in reference to weight training, I believe simple calisthenic exercise to be low enough impact that doing push ups and sit ups every day is a good thing. My approach is to do as many reps of each as I reasonably can each day - right now that's 200 sit ups and 100 push ups per day (in sets - 40pu/100su/30pu/100su/30pu) He says I'm overdoing it, while I say I need to keep up the everyday pace and continue to add reps. Is there such a thing as overdoing it on calisthenics? I say no. Am I wrong?
