Actually, now that I know from what Corribus is also running from, I pity him and I'll leave him alone for a while.
Oh, yes, gymnastic guys are really sturdy and strong. They are accomplished at doing plyometric kind of exercises, which are meant for explosive purposes. These exercises gives you quite a lot of mass, tonus and details, but not much stamina and muscle endurance. To achieve the best results, as we could say for people who go for FITNESS and not for bodybuilding, they have a balanced training (of course, considering all those matters around food, rest, etc.) between endurance, explosion and strength, mainly for endurance and much less for strength, whether at bodybuilding you focus on strength and volume - the latter you may achieve using many sort of trainings as well, some that will respond better for your body, and this response you'll find out after several years of training, when you start getting to know your body better.
Gymnastic guys are not build to endure much more time at those exercises I believe, or they can badly get injured. So, they work hard for that single moment which means fast-response muscle fibers (white). If they'd keep up doing trials or else, it'd be like forcing themselves beyond repair, causing muscle collapse, rather before fadige that you train endurance by training slow-response muscle fibers (red), which are those we, bodybuilders, train but not as much as those who run long distances do. That's why we must always change our training program to make the body confused and respond in a better way to all stimulation you apply over it. After you add some mass upon it, you can strengthen it, then detail it, then grab some mass again, increase stamina.
I'll be much different in several months. Not like a treeant.
