This exercise increases the difficulty of the side plank by lifting the top leg.
To do this exercise you will need a mat. Start by lying on your side with your legs lengthened long beneath you. Place your hand under your bottom shoulder to lift your torso. Inhale into the back of your ribs and then exhale as you lift your hips into the side plank. Inhale into the back of your ribs again and then exhale as you lift the top leg.
Things to think about
Lifting the top leg creates quite a balance challenge for the body. Using the exhale to stabilize the spine will also provide the strength needed for this balance challenge
Shoulder stability is really important to this exercise. Be sure that you are widening your collarbone and connecting your arm deep into the shoulder socket.
