Exercising on the treadmill can be an awesome workout—but most of us don’t know where to begin. Instead of going for a boring run at the same pace and incline for half an hour, give your body (and your booty!) the workout it really wants! Taking advantage of this workout’s varying intervals and inclines, you’ll burn major calories and work your way to your best butt ever in just 30 minutes. Happy running, collegiettes!
