London · Performance & Longevity Coach
For driven professionals who want more than aesthetics. Build lasting strength, move better, and create habits that change everything — for good.

With 21 years across powerlifting, bodybuilding, and gymnastics, Mckenzi has spent two decades learning what actually works — and what doesn't. Now, he brings that experience to clients who are serious about changing their life.
His approach goes beyond the gym. Small, consistent habit changes compound over time into a completely different way of living. Better sleep. Better movement. More energy. A body that works for you — for decades to come.
"It's not about one big change. It's about micro-habits that stack — until one day you look back and realise your entire life is different."
— Mckenzi Sager
My flagship programme — built for driven people who want real, lasting results without being tied to a location. We start with a full consultation, then I build your custom training and nutrition plan from scratch. Every week we check in, assess progress, and adjust. No templates. No guesswork. Just a programme that works around your life.
Limited spaces available.
Consultation required before booking.
One-to-one sessions at Top Notch gym, Soho & Mayfair. Technique-led, progressive, and entirely tailored to where you are right now — and where you're heading.
A holistic approach to performing well for life — mobility, sleep optimisation, recovery, and the daily habits that determine how you age. For people who think long-term.
Session expiry: All session packs expire after 180 days from purchase. Cancellation policy: Sessions cancelled within 24 hours will be charged in full.
We start with a conversation. I learn about your goals, history, lifestyle, and what you actually want your life to look like.
I build your fully bespoke training and nutrition plan — structured, periodised, and designed to evolve with you over 12 weeks.
You get to work. Every session is purposeful. Every week builds on the last. Progress is tracked and adjusted in real time.
We review, adapt, and keep pushing. Small consistent changes compound — until one day you realise your entire life has shifted.



Training with Mckenzi has been life-changing. I went from 65kg to a muscular 90kg thanks to his expertise, dedication and holistic approach. He's 100% dependable and makes every session enjoyable.
I first met Mckenzi through my physiotherapist, while I was recovering from ACL surgery. I'd stopped training for months and lost my strength and physique. Since then, Mckenzi has gotten me into the best shape of my life, better than before the injury. He's trained my mind as much as my body, and I've become more resilient, stronger, and genuinely happier. Working with him has been one of the best decisions I've made.
