Stand up straight with the water at chest depth.
Hold a noodle in each of your hands by your sides with your elbows straight.
Gain your balance and then slowly lift your feet off of the floor behind you. Hook your feet under a poolside rail to help stabilise you.
Ensure you keep your elbows straight with your arms pointing towards the floor.
Do not hunch your shoulders.
Keeping your elbows straight, slowly allow your arms to float out to the sides, towards the surface of the water.
Push the noodles back towards the start position.
Repeat.
