Serious topic.
I read an interesting article about the ultimate limits in athletics. Scientifically a best ever marathon in 1 h 55, 100 m sprint in 9.25 sec and stuff like that.
What will be the limiting factor in bodybuilding. Is it that at some point the muscle is so big and strong that it will tear the tendon of the bone when training for more size ? Or will the digestive system be unable to keep up? Or will the size of a biceps prevent full contraction necessary for further growth? There will be new drugs and stuff, but we still have the same bone structure and circulation and so on.
What will mr. O 2050 look like and where will/must it end ??
