Not all pools have stairs but you can still perform this exercise by using aqua aerobic stepper instead. Jumping in the pool, unlike on dry-land, creates high intensity, yet smaller impacts on your joints.
Jumping in the pool also engages more muscle groups, especially you upper body muscles, and keeps you cool and refreshed all the time.
Stand in the shallow end with your hands open by your side and your legs closed together.
Place the noodle under your arms and go to the standing position in the deep area. Rest your hands and forearms on the noodle, relax your shoulders and flex your feet.
