This is completely wrong though. This was obviously written by a fatty that has no idea about metabolic processes or actual exercise. There is not a chance in hell that 1152 push ups are 1152 calories:   Work = force × distance. If you have longer arms or weigh more, you need more work for a push up   Most of the calories burned from strength training come in the form of rebuilding the damaged muscle tissue and increased tyhroid activity. If you did 1000+ push ups your body will be spending a lot of energy rebuilding those muscle fibers.
