Fat-Proof Your Butt

Take the jiggle out of your wiggle with this super-firming move to target muscles in your butt.

You've squatted and lunged with the best of them, yet your butt still won't shape up. What gives? You've learned the first truth about the backside: It's stubborn! While some muscles respond quickly to exercise, the butt often—pardon the expression—lags behind, since it naturally carries more fat. The key to targeting the whole bunch of muscles (there are 10 to be exact) is to keep your leg moves varied. We asked Los Angeles-based trainer Keli Roberts to give us some butt-defying exercises, one of which is featured here, that hone in on all the muscles back there. Do our workout as featured in the July issue ofFITNESS at home or in the gym; all you need is a bench or step and a pair of light dumbbells. Do one to two sets of 10 to 15 reps for each move, three times a week. Add some cardio activity to your routine, and within six weeks, you'll be sitting pretty with a brand-new behind. Now, squeeze it!
