HOW: Get set-up in a table top position as shown in the video with a band around your back under your arms, then criss-cross the band in front of you and hold the ends of the band in each hand. While keeping your low back flat into the ground, lift your arms up overhead while keeping your arms and hands rotated out. With your arms in the overhead position, your thumbs should be facing down towards the ground. Slowly return to starting position and repeat.
FEEL: You should feel your shoulder and shoulder blade muscles working in this exercise. You should feel your shoulder blades moving away from one another and ‘wrapping’ around your body towards your armpits. You should also feel your core muscles working to keep your lower body and legs still.
COMPENSATION: Do not arch your low back, do not flare your ribs, do not shrug your shoulders.
