Butterfly
The butterfly stroke calls for you to bring both arms over your head at the same time and push them into the water to propel yourself. The butterfly stroke uses a dolphin-style kick, which means that your legs will stay straight and together as you kick them through the water. When using the butterfly stroke, you must remember to stabilize yourself with your core and create a rhythm between the underwater and above-water portions of the stroke.
