Pretoria East's home for HYROX race preparation and expert personal training, building strength, endurance and confidence for every level, from first-timers to World Championship athletes.
Who we are
Trainingwithstef is a leading HYROX Training Club and personal training facility in Pretoria East. We help beginners, fitness enthusiasts and competitive HYROX athletes build strength, endurance and overall fitness through professional coaching and structured programming.
Our mission is simple: help every client become stronger, healthier and more confident, whether you're preparing for your first HYROX race, chasing the World Championships, improving athletic performance, or simply living a healthier lifestyle.
Trainingwithstef isn't a commercial gym that happens to offer HYROX. HYROX is one of the core things we do.
One of the first HYROX Affiliated gyms in Pretoria.
What we do
The closest you can get to race day without actually being at a HYROX event.
Structured HYROX and hybrid training on official HYROX equipment, for every level from first-timers to competitive athletes.
Structured HYROX training built around the eight official stations and 1 km runs, the fastest way to build a race engine.
Hybrid training is a style of training that combines multiple fitness qualities rather than focusing on just one. The goal is to become strong, fit, and well-conditioned at the same time.
Run the full HYROX format on official equipment before race day. Open to athletes from any club or gym, whether it is your first event or a push for a PB.
The story behind TWS
TWS started with one person and a love for health and fitness. Clients came asking for Stefan by name, until 21 December 2010, when he and his wife Monique were in a serious car collision.
Stefan was airlifted to Durban and spent 16 days in a coma. Then he had to learn to sit, walk, talk and eat again. Monique stood by his side the whole way.
"I decided not to let the situation get me down. I will motivate and help people with whatever they need to accomplish their goals."
Today he coaches athletes who travel in from across Pretoria and Johannesburg to train at the Wolwespruit trails, with 20+ years in bodybuilding, strength & conditioning, kettlebells, Olympic lifting and nutrition, and a first-hand understanding of what it takes to rebuild.

60 kg down in a single year
"In 12 months I lost 60 kg's and feel like a new person."
Best Hyrox gym in Pretoria. Includes personal training, functional fitness and regular hyrox simulations. Individualized training with state of the art equipment.
We love the location and the open air nature of the gym. Stef has invested in top of the line equipment and being a Hyrox affiliated gym it's a superb place to train. Highly recommended.
I started at TWS just for the Personal Training, but never thought I would be able to attempt HYROX. Stefan is an incredible coach and I believe this is the best place in PTA for HYROX and personal training!
Fantastic HYROX gym! Stef is an excellent coach, super knowledgeable, focused, and truly invested in helping you reach your goals.
Great atmosphere and great Hyrox training! All the equipment you need and Stef is a great trainer too!
From day one he created a welcoming, professional environment where I felt supported, challenged and motivated to push past my limits.
My daughter and I have been training with Stefan for two months now. We look forward to training every time, Stefan and his team know what they are doing, and the whole vibe is just incredible.
Really enjoyed a Hyrox sim at Training with Stef. Equipment is in an excellent condition.
As seen on
kykNET's lifestyle show Kwêla came out to see how TWS trains, outdoors, HYROX-style, and open to every level. Have a look.
