Start in a side plank position with your elbow on the ground and your feet stacked on top of each other. Engage your core and lift your hips off the ground, creating a straight line from your head to your feet. Once you are stable in the side plank position, lift your top leg up towards the ceiling while keeping your hips lifted.

Place either your right or left elbow on the floor, lift your hips, and extend both legs. Balance on the outside edge of your bottom foot and lift top leg up just a bit higher than your hip. Slowly lower top leg back down. Repeat on the other side. Do 15–20 lifts per leg.

Lie on your right side and press up into a side-plank position, with your forearm, and foot on the floor, and your body forming a straight line from head to heels, with your upper back, glutes, and heels against a wall. Keeping your legs straight, squeeze your glutes, flex your left foot, and lift your leg straight into the air.

How-to: Start in kneeling side plank on your right arm. Then extend your left leg out to the side. Your weight should now be supported by right arm and knee. Slowly lower your left leg until toes touch the floor. Squeeze your inner thighs and lift left leg back to the starting position. Complete 3 sets of 8–12 reps per side.
