Side Plank with Leg Raise
To do the Side Plank with Leg Raise from your forearm, set up on your side and prop yourself up on your forearm with your elbow right below your shoulder. Your legs should be out straight. You can either stack your feet or place your top foot on the ground in front of your bottom foot. Beginners may need to place their bottom knee down on the ground.
Then, driving through your forearm and the sides of your feet, lift your bottom hip up off the ground as high as possible while keeping your body in a nice straight line. Squeeze your belly button in toward your spine and keep your glutes tight. Do not let your chest rotate forward toward the ground or your top hand touch the ground. Keep your top hand on your hip or reach it up toward the ceiling.
Holding this Side Plank position, lift and lower your top leg up and down. Do not let your hips drop toward the ground as you lift the leg. Keep your legs straight and that perfect Plank position as you lift and lower that top leg. If this lift is too much, try it from your knee.
