Back Stroke
Head - In-line with spine
Eyes - Looking straight up in longer events and slightly back towards the feet in shorter events
Shoulders and chest - Rotate around central axis of spine in same plane as hips. High shoulder is on recovery arm side, low shoulder on pulling arm side
Arms - Arms are always 180-degrees from each other. Arm speed is controlled by kick speed. Recovery arm is straight from wrist to shoulder and points straight up
Forearm and hand pull - Propulsive surface, line from fingertips through wrist and elbow starts pointing towards the bottom and side of the pool, rotates more towards the side and surface of the pool, then finishes releasing the water towards the feet and under the hips; reach towards the bottom, then arm-wrestle, then throw something into your pocket.
Forearm and hand recovery - Straight arm from shoulder through wrist
Forearm and hand entry - Pinky first, directly above and just outside the shoulder with arm fully extended, with body rotation allowing entry hand to reach deep into the catch
Trunk - Must maintain the connection between the shoulders and the hips
Hips - Rotate around central axis of spine in same plane as shoulders. Attempt to initiate body rotation from the hips
Legs - Kick is steady 6-beat, with faster tempo resulting in faster hands
Feet - Faster feet = faster pull = faster swim. Boiling water at the toes is not only OK but encouraged to facilitate better follow-through on the kick
Breathing - One breath per cycle; inhale on one pull, exhale on the next pull
