Want a sexy rear view? And while you're at it, legs that look great as they propel you through life? This workout is the best way to get them. Based on plyometrics—moves that incorporate leaping, jumping, or skipping—it burns calories and builds lean muscle fast.
A 2007 study found that dancers who did plyometric exercises twice a week for six weeks increased their strength by 37 percent and their jump height by 8.3 percent. "Plyometrics are a good alternative to strength training on machines," says Patricia Fehling, Ph.D., the study's co-author and chair of exercise science at Skidmore College. "The change in movement from static [say, the bottom of a squat] to dynamic [exploding into the air] shocks your muscles, so you see results quickly."
For two weeks, do the workout once a week, then increase to twice a week. Start with one set of 10 reps of each exercise, then add one set of each exercise weekly until you reach the max: three sets of 10 reps twice a week. Finish each session with the two kink-busting stretches.
