Slideboard Bridge to Curl
Lie on a slideboard on your back or with your hips at the end of a slideboard top. Bridge your hips off the ground while keeping your legs straight and then slowly bend at the knees and slide your feet toward your butt. While your feet come in, continue lifting your hips off the board—keeping a straight line from your shoulders through your hips to your knees. Continue curling your feet toward your body until your legs reach a 90-degree angle. Then, slide your feet away toward the starting position. Do not let your hips touch the ground until you have completed all the reps.
