Swim Jim, New York

It’s safe to say Catherine Fox knows her way around a pool. She won an Olympic gold medal for her ability to find her way from end to end. Partnering with Swim Jim owner Jim Spiers, a trainer for 2012 Olympics Bronze medalist Lia Neal, the pair transformed their expertise into a curriculum that helps others learn to love the water as they do. The resulting program, titled the Underwater Schoolhouse, forms the cornerstone of every class held at Swim Jim.

Teachers take on students of all ages, focusing first on helping to cure land dwellers’ inherent nervousness around water. To do this, they use a combination of encouragement and humor, never pushing a student further than they’re willing to go. Once students take the plunge, the coaches focus on teaching the mechanics of a variety of strokes, such as how to kick during breaststroke or how to emerge gracefully from the chrysalis before butterfly stroke.
