PERSONAL TRAINER INSTRUCTION :
Run the band under a bench as you lay on your back (supine) on the bench. Elevate your elbows so they’re perpendicular to the ceiling. Flex the elbow so the band is next to your ears.
Begin by extending both arms up in a synchronized fashion. Slowly lower back to the starting position once the arms have been fully extended. Exhale as you extend your arms.
Focus on keeping the elbows “locked” into a single position while the forearm does all of the moving. To make this exercise easier, use a lighter band or try it with light dumbbells.
