Best Ab and Butt Moves You Have Not Tried

To score tighter abs or a firmer butt, most of us think we need to (groan) work out longer, harder or more often. There's some truth to that. But, to get the job done fast, you can also try some fresh exercises you've probably never seen before.

Why is exploring something new so important? "When you do the same moves all the time, you tend to plateau," says Andrea Bowman, M.A., C.S.C.S., a certified trainer in Virginia Beach, Va. But the six moves Bowman prescribed exclusively for Shape give your muscles a change of pace. These supershapers fire up your muscle fibers and stimulate positive changes. Depending on your goals, you can incorporate one or both trios of exercises into your regular program. In just four weeks, we guarantee your abs and butt will be out of their rut.
