A Butt-Toning, Calorie-Burning Interval Workout
It's time to combine some booty-toning hills with some calorie-torching cardio to work your backside. Working the incline on the treadmill targets your hamstring and glutes! This calorie-torching workout combines bursts of running with quick hilly walking as you play with speed and incline. It moves so quickly that there is no chance for you to get bored.
