I’m David O’Connor, a Hampstead-based personal trainer working with busy professionals over 40 who want to feel stronger, leaner, and more confident in their bodies.After years of working in gym environments, I noticed the same pattern repeatedly — people training hard, but not always training intelligently. Many were pushing through pain, accumulating injuries, or burning out rather than building strength that actually supported their lives.

 

My Training Philosophy

​

My approach to training has also been shaped by my own experiences with injury, including a meniscus tear and shoulder impingement. Going through that process first hand gave me a much deeper understanding of how important good movement, posture, mobility, and intelligent load management really are.

 

Those experiences helped define what longevity training truly means — not just training to look fit now, but training in a way that protects your joints, supports long-term health, and allows you to keep moving well as the years go on.

​

Who I work with 

 

Today, I specialise in strength training, fat loss, and longevity-focused coaching for over-40s. I also work extensively with clients returning to training after injury, helping them rebuild strength safely, improve movement quality, and regain confidence without fear of setbacks.

 

My coaching prioritises:

 

• Joint-friendly, well-structured strength training

• Posture, mobility, and movement quality

• Sustainable fat loss and body composition

• Long-term progress over short-term extremes

 

I believe training should enhance your life, not dominate it. My goal is to help you look better, move better, and feel stronger — now and well into the future.
