Minute Arm Workout

Good news: You don't have to pump major iron to beat dreaded arm jiggle. To help you get sleek, sculpted arms in time for tank-top season, we asked Michael Olajide, co-owner of Aerospace HPC studio in New York City, for a routine that's low on equipment and big on benefits. And it takes just 20 minutes!

This seven-move workout, based on Olajide's Aerosculpt class, requires nothing more than your own body weight, a jump rope, and a set of 1- to 2-pound hand weights. Begin by skipping rope, which helps tire out your arm muscles. "This way, you won't need to lift much weight to achieve results, " explains Olajide. Instead of counting reps, you'll count seconds for an easy-to-follow routine that blasts fat as it sculpts muscle.

Do each move in order without rest for 60 seconds (or until your muscles are exhausted), then repeat twice more. Done three times per week, this routine will sculpt your arms from your shoulders to your fingertips in less than a month!
