Below is what most swimmers will find enables them to do what I did, which is going from 21 strokes per 20-yard length to 11 strokes in two workouts with no coach, no video monitoring.
Alumisel pildil on asend, mis aitaks saavutada  minuga sarnase tulemuse ehk alustada 18 meetri ujumist 21 tõmbega ja jõuda siis 11 tõmbeni, seda vaid kahe treeninguga, ilma treeneri või video abita.
