Stand in the shallow area by the side of the pool. Rest one hand on the wall/edge and keep your arm straight. Put your other hand in the water on your side and relax both your shoulders. Step on the noodle with your far foot and spread it slightly to the side (up to 45°). Keep your back straight and your body weight on your leg, not on the wall.
With your leg sideways, bend your knee up (a little more than 90°), then push the noodle to the side as you extend your leg, returning to the starting position. Perform this exercise with your leg always out and do not close.
One leg extension with inhale and one with exhale.
Feel your quadriceps as you push the noodle to the side.
Warning: For hip injuries do not spread your leg beyond 40°
