HOW: Begin by lying on your side with your leg together. Slightly bring your knees up towards your chest. Loop a band around both knees. From here, use the top knee to push against the resistance while your feet stay together. Bring that knee up and hold it for the prescribed amount of time and reps.
FEEL: You should feel your hip muscles working.
COMPENSATION: Don’t lean back and open up your hips as you push against the band.
