Stand up straight holding a resistance band in both hands.
Hold your arms above your head shoulder width apart and gather the ends of the band round your hands to create some tension.
Keeping your shoulder blades relaxed and your neck long, bend your elbows pulling the band down towards the top of your head.
Ensure your elbows move out to the side and your forearms remain vertical.
Control the movement as you raise your arms back up to the ceiling and repeat.
