Butterfly is the second hardest stroke to learn how to swim, just behind breaststroke.  It’s by far the most physically demanding, so learning to swim an efficient butterfly is essential to success with the stroke!  Cookiecutter and Lemon sharks will work on “dolphin” kick and get introduced to the butterfly arm motion.  Leopard, Hammerhead, Tiger, Great White, and Mako sharks will focus on stroke efficiency with drill work to develop butterfly arm posture, promote good breathing, and establish a two-kick rhythm.
