In the first 3 weeks I noticed a difference. By week 20, I had burned 12% body fat and lost 20 pounds. The best part? I increased my lean muscle and my clothes have never fit better.

About Stuart
Progress you can see in the numbers
Stuart has been at Arzadon Fitness for over five years and brings more than a decade of experience to the floor. His work is defined by structured progression — tracking the right metrics, catching plateaus before they take hold, and adjusting programming with enough precision that effort actually translates into measurable change.
The depth of his methodology reflects where he's invested his continuing education. He's studied lower back integrity under Dr. Stuart McGill, advanced hypertrophy with David Lawrence, and built his programming foundation through Kilo Strength Society. Every variable in a program Stuart writes has a reason behind it, and every session is connected to the one before it.
For clients who want accountability that doesn't waver and progress they can see in their numbers, Stuart is the Transformation Expert who makes sure neither slips.

Common Questions
About Stuart
What certifications does Stuart Charlesworth hold?
+
Stuart holds certifications including NSCA-CSCS and Poliquin BioSignature, with additional credentials in strength and conditioning and nutrition. He has been coaching at Arzadon Fitness for over five years and brings more than a decade of hands-on training experience. His foundation is in structured progressive overload, regular measurement, and programming that adapts specifically to each client’s response.
What results can I expect working with Stuart?
+
Stuart’s clients consistently see body composition changes of 10–20 lbs of fat loss alongside increases in lean muscle, with his most documented results in the 8–16% body fat reduction range. The key driver is his insistence on tracking the right metrics — not just scale weight — and catching plateaus before they cost you weeks of effort. His average client achieves their primary goal within the first 16 weeks.
What is Stuart’s coaching style like?
+
Stuart is data-driven and precise but genuinely engaging. Clients consistently describe him as knowledgeable and dependable, with a sense of humour that makes difficult sessions easier. He listens carefully at intake, builds programs that push without breaking, and adjusts them regularly based on what the numbers actually show. The physician researcher Dr. Risto Filippi described working with Stuart as “science and data-rooted” — that’s an accurate summary of how Stuart works.
How do I start training with Stuart?
+
Every new client at Arzadon starts with a full diagnostic assessment: InBody 770 body composition scan, BioSignature measurement, and a movement screen.
