Get your freestyle arm recovery on track and feel your stroke improvement in efficiency and ease; feel your effort level drop down a notch too, as you begin to open up the possibility of using momentum, and gravity to assist propulsion. The ball and socket joint in the shoulder needs room to move in the same plane, throughout the entire recovery movement - helped by torso rotation; the arm needs to move in one smooth forwards action (not upwards or backward).... inertia does not like to stop and change direction. Travel forwards on top of the water to reach a 'tipping point' where you feel the arm taken by gravity and enter with no splash or turbulence or drag. Practice standing, practice short distance, improve by adding challenge of more distance and pace.
