What is the proper technique for executing the butterfly stroke arm movement in swimming?

Answer 1

To execute the butterfly stroke arm movement in swimming, start with your arms extended forward and together. Pull both arms simultaneously in a circular motion, bringing them out to the sides and then back together in front of you. Keep your elbows slightly bent and fingers together as you push the water behind you. Repeat this motion in a continuous and fluid manner to propel yourself through the water efficiently.
