[Vancouver, British Columbia] — [May 30, 2025] — Competitive swimmers and swim coaches looking to dominate their races now have a powerful new tool at their disposal.

The Dolphin Kick Manual: The Swimmer’s Ultimate Guide to a Fast Underwater Dolphin Kick is officially available, offering swimmers, coaches, and parents a proven, research-backed roadmap to mastering the “fifth stroke” and taking their performance to the next level.

Written by swim performance expert Olivier Poirier-Leroy, The Dolphin Kick Manual breaks down every element of an elite underwater dolphin kick, including timing, technique, frequency, amplitude, core control, mobility, power, and more.

Built on over 140 peer-reviewed studies and insights from Olympians, NCAA champions, and top coaches, the book is the most complete guide ever written on building a dominant underwater game.

“A fast underwater dolphin kick isn’t optional anymore, it’s essential,” said Poirier-Leroy. “This book is a detailed blueprint to help swimmers of all levels build a kick they can rely on for faster results in the pool.”

Key features include:

  • Evidence-based technique advice. Poirier-Leroy notes that over 140 studies were referenced in the book. “It’s the most detailed product of its kind,” he said.
  • Strength, mobility, and dryland programming. Swimmers are given guidance on crafting a strength training and mobility routine to support faster dolphin kicking.
  • Dolphin kick-specific sets and training tools. Bridging theory and practicality, The Dolphin Kick Manual includes 20 different sets to hone kick technique and conditioning.
  • A 6-week action plan to put knowledge into motion. “Knowledge is one thing,” said Poirier-Leroy. “Execution is another. The Action Plan is designed specifically to help swimmers apply the concepts from the book.”

Whether you're an elite sprinter looking for that extra edge, or a developing swimmer frustrated with slow underwaters, The Dolphin Kick Manual delivers the tools to transform your kick—and your results.
