When the rower buries both blades in the water in a squared position. Arms stretched, wrist flat in one line with the arms. Shins are vertical, the back straight up, leaned forward, chest touches the knees. Head is held upright , focusing on the horizon. When the legs finish to push, swing the back toward the bow by pivoting at the hips.
Arms pull in to finish the stroke.
Hands move in a straight line. Outset the blades by a quick down motion of the forearms. The hands feather the blades with a fast click. Lean forward your body behind your arms by pivoting your back at the hips. Keep the blades just free from the water surface.
