The coaching approach

Evidence-led. Athlete-specific.

Jack built Inner Athlete around a straightforward idea: coaching should connect the work completed in training to the performance required outside it. A programme is not successful because it is difficult. It is successful when it develops the right quality at the right time and fits the wider demands placed on the athlete.

That means beginning with context. Sport, position, training age, competition dates, technical practice, available equipment and recovery all affect what belongs in a programme. Testing and tracking are used to support decisions, while regular observation keeps those decisions grounded in how the athlete is actually responding.

Who Jack coaches

From fight camp to the workplace.

Inner Athlete has a strong foundation in combat and contact sport. Jack works with boxers, fighters, rugby and field-sport athletes, young athletes building long-term foundations, and everyday performers who want to train with greater intent.

The same principles now extend to workplace teams. Corporate performance coaching translates movement, posture, physical capacity and recovery into practical sessions for desk-based, remote and hybrid teams. The environment changes; the standard of coaching does not.
