⏱️ Video Timeline 01:35 The Most Important Core Principle (Wave) 03:15 How to Hold a Member's Hand Position During Instruction 04:02 Breathing, Gaze, and Head and Arms? This video was produced based on questions asked by a paid member instructor during actual instruction. "I can do one-arm butterfly well, but why do I not move forward when using only two arms, and instead just stand in place and raise my arms?" I will easily explain the wave and hip position—the most important aspects of butterfly—through actual demonstrations. Instructors, if you have any questions while teaching, please leave them in the comments. I will provide answers via video so you can utilize them in your actual classes. #Swimming #Butterfly #SwimmingLessons #InstructorAcademy #SwimmingInstructor
