Cheaters? Yes there are some. Steroid users still have to work just as hard only they get faster results.
Drug testing? I dont know about what association you belong to, but most ass. only test for dieretics. The sport is an entertainment show now, and no one wants to see the smaller guys they want to see the freakish bulging roiders. Its all about the audience, and i think it is too bad. If they had began testing in the first place it wouldnt have gotten to be like this. Same as fitness, it is turning into who uses the most to get to the top. I predict in a few years that no one who doesnt use will be able to be in top 10. Fitness will become extinct because no one wants to see man faced women.
Liposuction? i dont know anything about. Breat implants? well i knw alot about those. As a flat cheasted competitor we struggle with this everytime we hit the stage. In the pro ranks there are only a small handful (no pun intended) that dont have them. If fitness is your life and you (as a pro rank competitor tells me) can find 3 reasons other than vanity to get them, then go ahead. I can't find those reasons so i stay president of the itty bitty titty comitty. Breast implants do tend to even out a large shouldered woman and so some fitness competitors benefit from them.
Shaving? All i know is you have to get the hair off one way or another! For me as a female fitness competitor, i shave the legs the day before my first coat of tan, wax arms and bikini line, and shave the rest of the body. Make sure you let your waxed skin dry out at least one day before applying your tan. Yes you should shave or wax because you will look alot more vascular and cut. I know it souunds weird but as a female i have very light and minimal amounts of hair on my arms, but once i waxed them they looked alot better. It really doesnt hurt that bad if you let a pro do it.
Hope i have helped some.
