Rehabilitation That Rebuilds Strength, Confidence & Longevity

At Poseidon Performance, we help people recover from injury, move without pain, and build the strength to live fully — not just for now, but for the decades ahead.

Whether you’re coming back from surgery, managing long-term joint issues, or simply want to stay strong and independent as you age, our one-to-one coaching meets you where you are and moves you forward with purpose.

Every session is personalised, precise, and built around what works — helping you rebuild confidence, restore control, and move through life with ease and resilience.

Because real progress isn’t about lifting more — it’s about living better.

Because training with Poseidon isn’t just about what you do in the gym — it’s about how you move through life.

    Vadzim Pukhau

    Vadzim Pukhau, has had an illustrious career as a martial artist, earning the prestigious title of Master of Sport of the USSR. Throughout his journey, he has gained black belts in Brazilian Jiu-Jitsu (BJJ), Taekwondo, and Karate. However, years of high-level competition and rigorous training had taken a toll on his body, particularly manifesting in a chronic hip issue that significantly hindered his mobility and ability to compete at the highest level. When traditional rehabilitation methods proved ineffective, Vadzim turned to Nicholas Martin-Jones at Poseidon Performance for a more specialised and comprehensive approach.

Awesome training. Great workouts. Plus, I have some old injuries Nick was able to work around, educate me about, and really alleviate. The injuries got better as time went on and became less stressful over time to the point I'm almost fully functional.
