“After writing the book “The G Point, a book about squash,” I was introduced to a sports science research group, which in turn led me to learn about “Differential Learning,” and I began to test his concepts in squash.

Accepting that repetition is the least effective sports training system set me on a path of discovery that continues to this day. When I started applying these new concepts to squash, both as a player and as a coach, I quickly realised that this different way of learning delivers interesting results.

“I am passionate about squash and about helping people improve, whatever their fitness, age and current level, and I set up Gevolution Squash in order to to share my ideas and experiences with other squash enthusiasts.”


Tony Griffin, Founder, Gevolution Squash

What makes Gevolution squash different

  • We use variety rather than repetition.

  • Our methods are based on the sports science differential learning and contraints-led methods.

  • Players learn how to watch the ball properly at all times.

  • We use techniques that encourage the body to position itself instinctively.

  • As play becomes intuitive, nerves subsides resulting in tighter shots and fewer errors.

Why switch to Gevolution Squash? Players who use our method:

  • make small but noticeable improvements faster than with traditional training systems...

  • ... and retain these for longer.

  • Are more engaged and focused, both during sessions and when playing.

  • are better able to adapt their movements to constantly changing circumstances.

  • adopt more natural movements and feel more comfortable on court.

  • enjoy the variety in each session and feel less frustrated.

  • improve their body's natural ability to organise itself, even in activities other than squash.

  • enjoy being a member of a community in which they can share experiences and support the development of the Gevolution Squash method.

  • can join our monthly online meeting, hosted by Tony, where they can ask questions about specific issues and share their experiences.
