Why: The jumping motion in this exercise is a great way to work on your strength and your speed at the same time, says DiDio.
How: Stand with your feet slightly more then hip-width apart, toes facing out. Bend your knees and lower into a Sumo Squat, then jump your feet together, straightening your legs. Immediately jump your feet back out, landing in a Sumo Squat. Do 10 reps for 1 set.
Why: This is Cosgrove’s go-to move for stronger, slimmer inner thighs. Not only does it challenge your inner thighs, but it also works your whole body to burn major calories.
How: Start in a standing position. Step directly to the side with your right foot, keeping both toes facing forward. Stick your butt out and sit back on your hip and heel as if you were about to take a seat. Return to starting position and repeat. Do 12 reps on each side for 1 set.
