Do this exercise on your hands and knees. Keep your knees under your hips and your hands under your shoulders. Keep your spine in a neutral position (not arched or sagging). Be sure to maintain your neck’s natural curve:
Tighten your stomach muscles and extend 1 leg straight back. Don’t arch your back or let your head or body sag.
Hold for 5 seconds. Return to starting position.
Repeat 5 times.
Switch legs.
Stop the exercise if it causes pain. Talk about it with your physical therapist or healthcare provider.
