[quote=harinezumikouken] I saw this problem a lot as a Marine. There were plenty of giant muscle-bound meatheads who could barely run a mile. The protein guzzlers would just lift heavy with the sole goal of 'getting big' but their cardiovascular strength would fail as a result of not doing any cardio exercises whatsoever. I believe someone described it to me as the difference between muscle strength - how much a muscle could exert effort towards in one repetition, and muscle endurance - the ability for the muscle to repeatedly conduct an action over and over without tiring and with relatively good speed. EDIT: There also is a such thing as over-training, when you work your body too hard to the point where it goes into this emergency panic mode and begins to eat itself and break itself down in an attempt to keep you alive. [/quote] That generally happens when the amount of training your doing is disproportionate to the nutrients you are taking in. So if someone goes on an extreme workout routine without increasing there caloric intake or without consuming the proper nutrients that will allow there muscles to recover then the body will as you say enter a panic mode in which it will break down other muscles in order to free up the necessary nutrients. As far as exercise is concerned if you want to increase your endurance, speed, reaction times, and range of movement basketball is actually a pretty good way to go. Not that there is anything wrong with weight lifting of course but that is only if you are doing other forms of exercise along side it and taking a healthy enough break in between training different muscle groups. Anyways, Sixsmith, if you have us work out like that last OOC post suggests (I'm hoping most of it was in jest) then Sapphire is going to refuse and bring these things up IC.
