Stand in the shallow-end and hold the dumbbells with your arms straight in front of your body and as deep as you can. Keep your back straight and your shoulders in the water.
Keep your shoulders still, your hands shoulder-width apart, and bend your elbows up 90° then extend down as deep as you can, back to the starting position.
Extend once with inhale and once with exhale.
Feel your triceps muscle as you push the dumbbells down.
