/ENDURANCE SPORTSWIRE/ – Competitive swimmers and coaches have a new resource for developing and winning the underwater game—The Dolphin Kick Manual: The Swimmer’s Ultimate Guide to a High-Performance Dolphin Kick.

Written by swim performance coach and former national-level swimmer Olivier Poirier-Leroy, The Dolphin Kick Manual: The Swimmer’s Ultimate Guide to a Fast Underwater Dolphin Kick is the first book dedicated entirely to swimming’s so-called “fifth stroke.”

Combining over 140 peer-reviewed studies with insights from elite swimmers and coaches, the book dives deep into the science and technique behind the fastest part of every race.

“Underwater dolphin kicking is one of the most critical and frequently misunderstood skills in the pool,” says Poirier-Leroy. “This book gives swimmers the knowledge and tools to improve their underwater dolphin kick for more explosive breakouts, starts, and turns.”

The manual breaks down every element of a high-performance dolphin kick, from proper body undulation and kick amplitude to ankle flexibility, core strength, and dryland training. The book is in a digital format and is written in clear, practical language to help swimmers and coaches gain a deeper understanding of how the dolphin kick works and how it can be improved.

Sections include:

• Undulation – Swimmers will learn the mechanics of undulation, the foundation of an efficient underwater dolphin kick.
• Breath control – Respiratory endurance is essential for underwaters, and the book teaches how to improve this skill safely for longer breakouts.
• Dryland training – Comprehensive dryland sections targeting the muscle groups that power the dolphin kick are included. Strength training, mobility/flexibility, core training, and more.
• Kick amplitude and frequency – Swimmers will learn how to nail kick timing so that they have fast amplitude and tempo in their kick, leading to faster underwaters.

Readers also get training sets, technique cues, and proven strategies to develop explosive push-offs and maintain speed off every wall.

Whether you’re a competitive age-group swimmer, an aspiring Olympian, or a coach looking for an edge, The Dolphin Kick Manual delivers the tools you need to dominate under the surface.
