Swim Speed Workouts: Underwater Drill

In her books Swim Speed Secrets and Swim Speed Workouts, 4-time Olympian, gold medalist, and triathlon world champion Sheila Taormina reveals the swim technique used by the world's fastest swimmers.

In this video, Sheila explains how to perform the Underwater Drill. A few of the workouts in Swim Speed Workouts ask swimmers to swim the length of a 25-meter pool underwater so that they improve lung capacity, diaphragm strength, and improve their feel for the water. Don't perform this drill if you are likely to get light-headed. It's okay to pop up for air if needed.
