Why Strength Comes Before Conditioning
Most athletes arrive wanting to be fitter. Nine times out of ten, what they actually need first is to be stronger.

The Coach
Jack Daysley · Founder & Head Coach
Jack Daysley built Inner Athlete on a simple belief: every athlete is carrying more strength, more speed and more power than they’ve ever been shown how to use.
A qualified S&C coach with a BSc (Hons) in Strength and Conditioning from York St John University, Jack works from a private facility in Yorkshire: no crowds, no queues, no guesswork. Just deliberate, evidence-based training for boxers, fighters, rugby players and the next generation of youth athletes.
“Every athlete has another level. My job is to take you there, and prove it with numbers.”
The Facility
One space, one purpose. Sprint track, sleds, racks and a full free-weight arsenal, reserved for the athletes who train here. No queues, no crowds, no waiting for a bar.

1-TO-1
Fully individualised programming in a private facility. Every session coached, every rep accounted for, every block built around your sport and your season.

Capped groups, competitive standards. The intensity of training alongside serious athletes with the attention to detail of private coaching.

The full Inner Athlete system, wherever you train. Individualised plans, video feedback and week-by-week accountability, delivered worldwide.
FIGHT & FIELD
Specialist physical preparation for boxers, MMA fighters and rugby players. Built to make you harder to break and heavier to handle.
LTAD
Long-term athletic development for young athletes. Mentorship, movement quality and strength foundations that pay off for a whole career.
DATA
INSCYD and aero testing that turns your engine into hard numbers. Know exactly where you stand, and exactly what to train next.
For Business
Your team spends eight hours a day in a chair, and their bodies keep the score: stiff necks, dead posture, energy gone by 3pm. We bring the training floor into your workplace: posture, movement and recovery, coached the way we coach athletes. Sharper focus, fewer aches, and people who finish the day with something left in the tank.
Who We Train

Boxers and MMA athletes preparing for the hardest nights of their lives. Power, engine and durability for fight camp and beyond.
Collision-sport athletes who need to be strong at speed. Win the contact, dominate the last twenty minutes.
Young athletes developed properly, with patient, long-term coaching that builds the foundation everything else stands on.
You don’t need a fight date to train with intent. Get stronger, move better and feel more capable than you thought possible.

Not your ordinary training programme.
