Top arm is at side, out of water. Top hip and top shoulder point towards the ceiling. Bottom ear rests on bicep. Take in air through the mouth. Put students in the water, have them push off the wall streamlined, then roll and get into the starting position and just kick.
Students exhale first while keeping the ear on the bicep and roll to take a breath.
Have students practice on both sides. This will help them to bilateral breathe later on. Kick must be tiny, fast, and strong with one foot on top of the other. Ear must stay in contact with the bicep at all times. Bottom arm that is straight overhead should always be kept near the surface.
