Individual high-performance Strength & Conditioning focused on lower-body strength, power, explosiveness and physical preparation.
Professional Strength & Conditioning, performance testing and private personal training in Leeds with Dion Tsolakis — for professional footballers and basketball players, developing athletes, and everyday clients who want to train properly.
Professional sport is where our standards come from — not a requirement for walking through the door.
One client is an MLS footballer. Another is a Leeds United professional, a professional basketball player, a 14-year-old developing athlete — or a 40-year-old busy professional who wants to lose body fat, build muscle and get fitter. Every one of them gets the same standard of coaching.
Individual physical preparation built around your sport, your schedule and the demands of the professional game.
The strength, speed, power and robustness needed to progress — developed properly as you grow.
Football, basketball and beyond. Structured athletic development, not just more of your sport.
Professional, evidence-based physical development for your child, from a qualified coach with academy experience.
Lose body fat, build muscle, get stronger and fitter — with a plan, not guesswork.
High-quality private personal training that respects your time: efficient, structured and built around your week.

Individualised strength, power, speed, acceleration, deceleration, plyometrics, change of direction and physical preparation — built around your sport, physical profile and competitive schedule.

Professional standards. Personalised to you.
Tell Dion your sport — or that you don’t play one — and what you want to achieve. He’ll point you to the right service and personally arrange your sessions.
Measure. Understand. Improve. Programmes start from objective data, are coached to a professional standard and are re-tested, so progress is something you can see rather than something you are told — whether you are a full-time athlete or training around a full-time job.

Founder — Power For Speed · Lead Performance Coach — Leeds Performance Hub
Dion is the Founder of Power For Speed and Lead Performance Coach at Leeds Performance Hub, specialising in Strength & Conditioning, physical preparation, athletic development, personal training and performance testing.
With 10+ years of coaching and performance experience, he combines a strong academic background with practical experience across professional football, basketball, academy development, private performance coaching and personal training.
Dion also comes from a strong basketball background, having competed at a high level in Greece before developing his career in Strength & Conditioning — so he understands performance from both sides: as an athlete who has felt the physical demands of competitive sport, and as a coach applying evidence-based S&C and sports-science principles.
His professional football experience includes Bradford City AFC, across Development Centre, Academy Sports Science and Professional Development Phase S&C environments. He has also worked within the Leeds United Girls Academy (RTC) environment and held Head/Lead S&C and Physical Performance roles across football development programmes, including Ultimate Football Performance, Ultimate Football Coaching Academy and the Grammar School at Leeds.
Alongside elite sport, Dion has delivered individualised personal training and fitness coaching for general-population and international clients as a Personal Trainer at Sani Resort, Halkidiki, Greece — helping everyday clients lose body fat, build muscle, get stronger and feel fitter.
Today, through Power For Speed and Leeds Performance Hub, Dion works with professional footballers, professional basketball players, academy players, developing athletes across multiple sports and everyday clients who want the same professional standard of coaching.
You don’t have to be a professional athlete to train to a professional standard.
Dion’s experience isn’t limited to professional football. He has coached across the whole range — which is why he can prepare a professional footballer or basketball player, and just as well help someone lose body fat, build muscle and get stronger.

Every session is one-to-one, in a private professional environment rather than a crowded commercial gym — valued by professional athletes who want privacy, and just as much by busy professionals and everyday clients who want focused, expert coaching.
The weekly group timetable is published separately on the Group S&C page once confirmed.
