Start the Arm Reach 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.
Stretch one arm straight out in front of you. Don’t raise your head or let your supporting shoulder sag. Your goal is to maintain stability of your spine while you perform this movement.
Hold for five seconds.
Return to starting position.
Repeat five times.
