WHAT TO DO
1. Lie on the floor with a neutral spine.
2. Put your arms over your head making a “Y” shape and press them onto the floor.
3. Draw your shoulder blades downward then glide them back up, while still keeping your arms pressed into the floor.
4. Repeat this movement until all reps are completed.
WHAT TO AVOID
• Losing contact between your arms and the floor.
• Moving out of neutral spine position by arching your back.
• Lifting or flaring your rib cage
