The treadmill usually gets highest honors for flab melting and leg sculpting, but this routine may have you rethinking your go-to machine. Like jogging, stair-climbing torches mega calories (about 10 a minute, depending on your speed) and strengthens your thighs, butt, and calves. But it goes even further, taking your legs and glutes through a full range of motion, which is crucial for sculpting. The key is to choose a stepmill-the machine with the big moving staircase-instead of a stair-climber or stepper, which only require your legs to make small movements. This workout isn't easy (there's a reason a stepmill is always open when all the treadmills are taken!), but it's worth the sweat. Try it once and you'll discover why, in the quest to lose the jiggle, it pays to take the stairs.
