This twist on a traditional inner-thigh lift uses your bodyweight to add an extra core challenge.
How to do it: Lie on your right side with your right elbow bent below your shoulder and your left hand behind your head. Extend both legs out and then bend your left knee up to the ceiling, placing the bottom of your left foot on the inside of your right knee. Hover your right leg slightly off the floor with your foot flexed. Next, engage your inner thigh to lift your right leg higher. Slowly lower your leg back to hover above the floor. Repeat 15 times and then switch sides for 15 more reps.
Form tip: Keep your abs in tight and try not to move your upper body as you lift and lower your leg.
