Certified and expert kettlebell coaching with Dieter Heitzer - online coaching, private kettlebell training sessions, for strength training and functional fitness, build lasting fitness results with sustainable routines at the gym or workout at home

Hi, I’m Dieter - I’m a personal trainer and Master level certified kettlebell coach with a background in strongman, CrossFit, Hyrox, and kettlebell sport.

Over the past decade, I’ve tested every training style out there. One thing always stuck: Kettlebells work.

Not just for building strength - but for reclaiming confidence, moving pain-free, and getting real results without wrecking your body (or your schedule).

I train because I love the outdoors; hiking, challenges, adventure.

I coach because I want others to feel what I’ve felt: strong, capable, and proud of what their body can do.

Whether you're training for life, lose weight or chasing your next challenge, I’m here to help you get there.

Why are we passionate about kettlebell coaching programs?

Why you can trust our training methods.

Kettlebells have changed my life and the lives of the people I coach. I keep learning so you can get the best results.

What you can expect from your kettlebell coach.

Simple, Sustainable Fitness No fluff. No guilt. Just focused, effective training that fits your life — not the other way around.

Real-World, Results-Driven Programming Whether it’s hiking pain-free, keeping up with your kids, or finally feeling consistent — I design for life performance, not just aesthetics.

Deep Expertise, Human Approach You’re not a spreadsheet. You get precision coaching, personal support, and a plan that evolves with you.

Mindset & Resilience I know what it’s like to feel stuck. Fitness was my anchor after moving from South Africa to the UK — and I believe movement is one of the most powerful tools we have for mental health.

No Egos. Just Support. I’ll watch your form, listen on the tough days, and push you when it counts. I’m not just your PT — I’m in your corner, every step of the way.
