Does the Saber Improve Your Tennis? Here’s What the Data Shows

Over the past 12 months, I’ve been working with biomechanics researcher Dr Nick Busuttil to better understand one simple question… Does the Functional Tennis Saber actually improve your game? In this episode, we dive into the findings from that research and what really happens when players train with a constraint racket. We discuss how the Saber influences stroke mechanics, why players may initially feel less accurate, and how that “useful struggle” can actually help build better timing, contact awareness and more consistent strokes over time. Nick also explains why tools like the Saber can promote adaptability in your game, act as a circuit breaker in training, and how coaches and players can use it effectively in practice and warm ups. If you’ve ever wondered whether training aids actually work or if they’re just gimmicks, this episode will give you a clear, science backed perspective.
