My journey into the fitness world started at a young age when I got involved in Martial Arts and Rugby. I was vice world champion in Karate in 2008 and still have my Swiss rugby caps. In 2021, I did my first Ironman 70.3. Since then, I haven’t stopped accumulating as many finisher medals as I can. I’ve done fitness modelling for bodybuilding magazines in the UK and have been a strength, conditioning, and endurance-focused trainer for over 10 years.

Our Testimonials

Rami Z.

John Hendren’s strength training has been a game-changer for my intense endurance regimen. As someone who tackles full-distance triathlons, multiple half-distance events, and ultra marathons, I rely on John to keep my strength in top shape to support my heavy cardio workload. His workouts are incredibly effective—one session with John feels like three of my own. They’re tough but fair, focusing on what really needs to be worked without any unnecessary fluff. This targeted strength training complements my cardio perfectly, giving me that extra resilience when it counts.

Ilinca D.

Training with John Hendren at BYTX Personal Training Studio has been an amazing experience! He helped me go from having no swim background to completing my first Olympic-distance triathlon, including a 1.5km swim, thanks to his connection with an excellent swim coach. I’ve also gotten into cycling, which has been a new and exciting challenge for me. On top of that, with John’s guidance, I hit a new PB at the Zurich Half Marathon! His approach covers everything. I’m excited to keep working with him as I take on more triathlons and races!

Dani V.

John Hendren’s expertise in strength training has been essential for my ultra marathons. While I handle my own cardio, John’s structured and coordinated strength programs have kept me durable and injury-free, allowing for uninterrupted training. His guidance has also helped me build muscle, which keeps my overall fitness on point. For anyone looking to enhance their strength while pursuing endurance goals, John’s expertise delivers strong results.

Claudio C.

John Hendren is a total game-changer! Thanks to his online coaching with BYTX Personal Training Studio, I crushed my first half marathon with a time under 2 hours. John’s not just about running—he’s helped me shed weight and stay active. His strength training programs at the gym are spot-on, getting me leaner and healthier every session. I’ve been working with him for over 3 years, and he’s always got my back, keeping me on point. If you’re looking for a coach who delivers, John’s your guy!

Diana C.

I’ve been working with John Hendren from BYTX Personal Training Studio, and the results have been incredible! Thanks to his professional and structured approach, I hit a new PB at the Zurich Marathon 10km and excelled at the hilly Sarnersee 10km. John is always on top of everything—carb loading, strength training, and keeping me in the right heart rate zones to improve efficiency. He’s motivating and makes the whole process enjoyable, which is why I continue working with him for future races. Highly recommend!

Sacha F.

John's strength training programs have been a game-changer for my polo performance. Over the past five years, his expertise has helped me build a strong core, a durable body, and enhanced my agility. This has allowed me to excel in intense matches and recover quickly. I highly recommend John for anyone serious about improving their athleticism and look forward to continuing our work together for years to come!

Natalie D.

John Hendren is an incredible coach! Thanks to his online coaching through BYTX Personal Training Studio, I hit a new PB at the Zurich Marathon 10km and completed my first relay triathlon in Uster. His structured training helped me achieve multiple half marathons in training, but the best part is his focus on mental health and well-being. John’s belief in you is contagious—he makes you feel like anything is possible. As a coach who leads by example with his own fitness, he’s truly inspiring. Highly recommend!
