Diving? You have to have the body type to start and then keep weight off. A lot of the divers are ripped, but you don't need to be (i.e., you need to be in shape, but really don't need a visible six pack). It's an extreme skill sport. You don't need a lot of muscle mass and you don't need endurance. And, great flexibility is a must, and there doesn't seem to be a PED for that. The other thing is keeping your weight down. Of course there are things to help with that, but I'm really curious if there's really any sort of PED that divers consistently use.
