Stand by the side of the pool. Hold the wall with one hand. Step on the noodle with your far foot slightly in front of your body. Keep your other hand still by your side and your back straight.
In the deep area, hold the wall/edge/rail with two hands and stretch your arms to create enough space between your body and the wall. Step on the noodle with both legs down. Keep your back straight and get your body in standing position.
You can perform this exercise in two different positions - both provide similar results. The first position is by laying on your back in the deep area with the noodle under your arms and legs straight together, slightly below parallel. The second is standing position, with straight back and noodle under your arms. Both your legs down, straight together and as deep as you can.
