The experience
Training doesn’t have to be
hard or stressful.
Refuel sits between doing too much and doing too little.
It’s a chance to let go and, at the same time, do just that little bit more. Your cardio fitness improves. So does your strength. You don’t have to wreck yourself to get there.
The music leads. Bach, Debussy, Michael Meets Mozart, Beethoven’s 5 Secrets, and pieces I’ve written myself. It sets the pace so you don’t have to think about it, and it carries you through the parts that would otherwise feel like effort.
It’s time for you. Time to process whatever’s in your head, and then to let it go through music and movement.
No shouting. No intimidation. Nobody leaves more stressed than when they arrived.
You leave worked and open. Clear-headed and quietly energised. Not wrecked.
1. Functional Movement
Controlled, compound movements. The music holds a steady pace, so the effort stays even and nothing turns into a scramble. Every rep counts because every rep has time to be a good one.
2. Cardio Kickboxing
Real intensity, with a ceiling built in. The music sets the tempo and the tempo sets the effort, so you work hard without tipping into the kind of hard that costs you the rest of your day.
3. Deep Stretch
The part most classes skip. Slow music, slow breathing, and enough time to actually come down. This is where the hour finishes properly, and it’s the part people tell me they didn’t know they needed.
Why music leads
The music isn’t the background.
It’s the pacing.
Most training asks you to regulate your own effort while you’re already out of breath. Refuel hands that job to the music instead.
Fast, structured pieces carry you through the working sections. Slower ones bring you down at the end. You’re not counting, watching a clock, or being shouted at. You follow the music, and the music has already decided where the session is going.
Researchers who study music and exercise have found for years that people work at a given effort while feeling like they’re working less when there’s music driving them. Anyone who has run further than they meant to because of a good song already knows this. Refuel is built around it deliberately rather than by accident.
How Refuel started
I started tracking my own heart rate through every session, matched against what I was listening to. Not as a study, just curiosity about something I’d noticed.
The pattern was consistent enough that I stopped treating the music as the soundtrack and started treating it as the training tool. Refuel is what came out of that.
Bring your watch if you have one. I’m still collecting the data, and I’ll happily show you yours.

About Jo
The founder of Refuel
I’m Jo. I compose music, and I train people. Refuel is what happened when I stopped keeping those two things separate.
The idea behind it is simple: the right music doesn’t just change how a workout feels, it changes what your body does with the effort. Some of what you’ll hear in a session is Bach or Debussy. Some of it I wrote.
I run Refuel in parks and studios around Berlin, online for people anywhere, and as workshops for teams who want something for their people that isn’t a fruit bowl and a step-count challenge.
Training doesn’t have to be hard or stressful. That’s the whole idea.
