Varied Warm-ups and Leg Press Performance

Dr. GJohn Mullen Blog, Dryland, Training Leave a Comment

The precise warm-ups for dry-land and swimming are unclear areas. Finding the balance between warming up the muscles, yet avoiding fatigue is a fine line, which often requires individualization. Despite this, many coaches request the same warm-up for each swimmer. Moreover, the specific event likely contributes to the amount of warm-up required for the athlete. For example, the warm-up for …
