JOEY

Head Coach · ONYX · Berlin

I have coached for 10+ years and run over 10,000 sessions, in person and online since 2019.

I have prepared multiple athletes for their HYROX race, helped people get strong enough to avoid surgery, and coached everyday clients to lose weight and build muscle.

I do not run templates. Every programme is built around one person.

1:1 COACHING

The most personal way to train with me. I build and adjust your programme around your life, every week. Available now.

This is not a programme you buy and figure out alone.

I will build your training around your goal. Two ways in, one method: BUILD to lose fat, build muscle, and get stronger, or PERFORM for HYROX, hybrid, and your races. Direct access to me, and a plan that adjusts every week.

RESULTS.

★★★★★

"First HYROX done. Joey built the whole 8 weeks around my race date and I hit it feeling ready, not wrecked. The taper week made all the difference."

ONYX RACE · Berlin
★★★★★

"I was told I might need surgery. Eight months of proper strength coaching with Joey and I am training pain free and stronger than I have ever been."

1:1 Coaching · Remote
★★★★★

"Down 9kg and visibly more muscle. For the first time I actually understood what I was doing in the gym and why. That is the part that stuck."

Questions

FAQ.

Do you offer HYROX coaching? +
Yes. I coach HYROX and hybrid athletes online from Berlin, worldwide. Whether it is your first race or you are chasing a faster time, I build your plan around your race date and adjust it every week, covering running, the stations, strength and pacing.
Can you help me build muscle and lose fat? +
Yes. Losing fat, building muscle and getting stronger is one of my two main tracks. Most of my clients are not training for a race at all. I build your plan around your body, your goal and your schedule, and adjust it every week.
Do you coach online or only in Berlin? +
Both. ONYX is online coaching, so I work with clients anywhere in the world. I am based in Berlin, and everything runs through an app with weekly check ins and plan changes.
How much does coaching cost? +
1:1 coaching is 199 euros per month on a six month commitment, or 999 euros paid in full. You get your own plan, adjusted every week, plus direct access to me.
1:1 coaching or a programme? +
If you want me to build everything around your specific life, goals, schedule and history, and adjust it every week, choose 1:1 coaching. If you have one clear goal and you are happy to follow a proven plan on your own, choose the ONYX Training Plan. Not sure? DM me and I will point you the right way.
What is the ONYX Training Plan? +
An 8 week plan I write for you, up to four days a week, with your chosen focus of build or race. It is a one time payment with no coaching support and no weekly changes. You follow it on your own in the CoachRx app. A good place to start if you are not ready for full 1:1 coaching.
When does my training start? +
For 1:1 coaching, I build your first block as soon as you sign up and tell me about yourself, usually live within a few days. The ONYX Training Plan is delivered to the app once it is available, so you can start when you are ready.
What equipment do I need? +
For 1:1 coaching, I build everything around whatever equipment you have, so just tell me what you can train with. The ONYX Training Plan is built to your focus and can be adapted to a gym or a simpler setup.
What app do I use? +
Everything runs through CoachRx, on iOS and Android. Once your payment is confirmed you get an invite to download the app and access your plan. Session logging, personal best tracking, health integrations and your training calendar are all inside it.
