Mickey Wender, former state swimming champion for the University of Vermont and Head Coach for the University of Washington, presents a comprehensive training film for perfecting a powerful butterfly stroke, encompassing meticulously focused drills and expert instruction on the crucial arm stroke and dolphin kick as well as maintaining rhythm while undulating. Wender personally enjoys exerting an intense effort, since he runs extreme endurance races, including Ironman triathlons and the 1996 Eco Challenge; the coaching depicted in this film reflects that extraordinary level of commitment.
