David Turnbull — Founder & Head Coach, TurnFit Personal Trainers
David Turnbull, known to clients as “Coach David,” is the founder of TurnFit Personal Trainers and the creator of the TurnFit Method. A BCRPA-certified personal trainer with over 15 years of coaching experience, David has helped hundreds of Vancouverites build strength, fix their posture, and create habits that last — earning TurnFit 8 consecutive Top Choice Awards and 300+ five-star reviews along the way.
The TurnFit philosophy
David built TurnFit on a simple belief: personal training should empower you, not create dependence. He trains every client “as if they’re becoming a personal trainer themselves” — teaching the why behind every movement so clients leave each session more knowledgeable and confident.
His coaching focuses on posture and movement quality — not just in the gym, but in how you stand, sit, walk, and move through daily life. By reconnecting the mind to the muscles that matter, David helps clients move the way they did as kids: freely, powerfully, and without pain.
