I’m Jurgens — an exercise physiologist and athletic trainer with a degree in exercise science, physiology, and kinesiology. Over the years I’ve had the privilege of guiding a select group of clients, from national-champion triathletes and Comrades Marathon runners to a remarkable 68-year-old who summited Kilimanjaro. Every one of those journeys reinforced the same conviction: exceptional results come from precision, not guesswork. My approach is grounded in human movement science, psychology, and rehabilitation. Each program is built from the ground up around one person — their goals, their physiology, their life. Whether the aim is strength, endurance, longevity, or a return from injury, the work is deliberate, measured, and entirely private. Beyond in-person coaching, I work with clients anywhere in the world through my custom training app, and deliver discreet corporate and team programmes for organisations that value their people’s performance. Wherever you are, the standard of attention does not change. Here’s what some of my clients have to say:”Jurgens has been working with my partner and me for some years. Apart from the improvement in our general fitness, he has been great at helping us avoid and in some cases take care of injuries.
