Stand up straight with your feet shoulder-width apart.
Grasp the handles in each hand.
Hold your arms out straight in front of you, palms facing down, and lean backward, pivoting off your heels.
Tighten your buttock and abdominal muscles.
Keeping your body in a straight line, pull your shoulder blades together, bend your elbows out to your sides, pulling yourself back towards the upright position.
Your arms should stay horizontal to the floor.
When your elbows reach 90 degrees, rotate your forearms upwards until they point towards the ceiling.
Ensure your elbows stay up.
Control the movement as you slowly return to the starting position.
De-rotate your forearms, then slowly straighten your arms back out.
Repeat.
