Swimming (Backstroke)

How to do it

Float on the back with the body level, ears in the water, and arms extended along the sides.
Rotate one shoulder up and back to begin the stroke, sweeping the arm in a wide arc overhead.
Pull the hand back down through the water past the hip, driving the stroke with the latissimus dorsi.
Alternate arms in a continuous windmill pattern while keeping the hips near the surface.
Kick steadily from the hips with a relaxed ankle to keep the body riding flat.
Breathe freely with the face clear of the water throughout each stroke cycle, keeping a steady tempo.
