Lie on your back with your feet supported under the wall bar and a noodle under your hips.
Rest your head back into the water and keep your body flat.
Hold a dumbbell float in each of your hands.
With your palms facing up, slowly take your arms out to your sides until they are in line with your shoulders.
Keeping your elbows straight, push the dumbbell floats under water leading with the back of your hands.
Pinch your shoulder blades together as you do this.
