|HOW: Begin by lying on a table or bed on your side. With your legs together, bend your knees up towards your chest to have your knees straight out from your hips. From here, let your lower legs drop down towards the floor while keeping your knees together. Once your legs are as far down as you can go, rotate them back up to the table height and perform for the prescribed amount of reps. FEEL: You should feel a stretch on the side of your lower back. You should also feel your low back and core muscles working. COMPENSATION: Keep your knees together, don’t let them come apart.
