How to do it: Lie on your back with your arms along your sides and palms pressing into the ground. Bend your left knee and place the sole of your left foot on the ground. Extend your right leg and point your toes toward the sky. Keeping your hips square to the ground, press into your standing heel as you lift your butt straight up into a bridge. Lower down with control, keeping the leg elevated the entire time. Complete 15 reps then switch legs, holding a dumbbell at your hip (pictured) for an extra challenge.
Where you'll feel it: Your butt and the backs of your thighs.
How to do it: Start in a kneeling position with your right hand on your hip and left palm on the ground to a few feet to your side. From this position, stack your hips as you extend your right leg out to the side. Engaging your core for stability, lift your right leg straight up, then lower it with control. Complete 20 reps then switch sides.
Where you'll feel it: Your outer thighs, butt, and waistline.
