Side Plank on Ball
Begin with the right side of your torso lying on a ball, your feet on the ground next to you, stacked. Straighten your legs and place your right hand on the ground, arm straight.
Hold this position, making sure you are not holding your breath. Try 15-30 seconds and work your way up to 1-3 minutes.
The ball assists you in this pose if regular Side Plank is too difficult for you.
