This is another variation of leg circles in the pool. Standing position is specially beneficial if you experience discomfort in your neck while performing noodle exercises on your back.
You will need a pool noodle (or any floating device). This exercise is performed in the deep-end where your feet can't touch the bottom of the pool.
In the deep-end, in upright position, place the noodle on your back. Rest your hands on the noodle and relax your shoulders. Straighten your legs and point your toes.
Perform little circles with straight legs. Focus on pushing the water with your feet. Start with forward circles, until you feel your muscles burn, and then reverse the other way around. Slightly lean your torso forward and backward too.
Circle your legs twice with inhale and twice with exhale.
Use your abdominal and lower back muscles.
Tip: Keep your movement controlled and don't push your legs too fast
