I'm sure saying this on a bodybuilding forum will piss everybody off, but bodybuilding is definitely NOT the most dificult sport to participate in. If by dificult you mean you have to have a dedicated drug schedule and diet, then you are correct. But I'm sure that anybody that has been through 3 hour wrestling workouts while on a limited diet would disagree. For me, an intense lifting workout is fun! And I go way beyond failure all the time. It is not hard at all compared to other stuff I have done. This is just my personal experience. Other sports that come to mind are marathon running, boxing, NHB fighting, swimming, and triathlons. Face it bodybuilding is easy! It is a lifestyle though, I will give you that. But so are all other sports at the top levels.
