Running not only burns calories, but it also does wonders for strengthening and sculpting your entire lower body. If you want to tone your legs and butt even more, give this calorie-torching workout a go. You can do our sculpting interval workout on a treadmill or outside; just increase the incline on the machine or find an actual hill on your outdoor route for the steeper intervals.This 53-minute workout, including a warmup and a cooldown, is full of walking lunges, high-knee running, sprints, walking uphill, and running sideways to target different muscles in your lower body. Pay special attention to the speed and incline so you know how fast and how steep your legs need to go.
