The Underwater Torpedo League—currently eight teams large—is based on the West Coast, but ad hoc games are popping up across the U.S. Newbies will need high baseline fitness, including sport-specific prep. But this demanding pool routine, created by Hall, is effective for anyone looking to level up their fitness. Try it once a week, and unless you’re a strong swimmer, do it under the watchful eye of a lifeguard. rest between rounds: 100meter freestyle swim, breathing every 2 strokes for the first 25 meters, 4 strokes for the second 25 meters, 6 strokes for the third 25 meters, and 8 strokes for the last 25 meters. Focus on efficiency, using a relaxed and methodical stroke rate the whole time. As you get stronger and more comfortable, add more rounds, up to 5 at a time.
