When your doing a Bikini competition your really are "working your azz off" however, not in workouts but more in your nutrition....ok wait in lunges and some cardio. 

I have to say Endurance Athletes work their Azz off in their endurance events, weights in high reps/body weight training and Bikini Athletes work their azz off in their nutrition, cardio and lunges for your gluts you have to tighten those suckers up they have to fit in that Tiny Bling, Bling Suit.
