Forge a stronger bodyPersonal Training in Heerenveen
At Groen's Fitness Forge you get more than a personal trainer. As a physiotherapist and trainer, I combine medical knowledge with effective training methods. The result: a program that not only works, but is also safe for your body.
The free intake with a trial session takes 60 minutes: we discuss your goals and you train along right away. No obligation.

The Forge method
The Forge method
My approach is based on three pillars: safety, effectiveness, and sustainability. We first build a stable foundation with the right movement patterns. From there, we systematically increase intensity. This way you make consistent progress without overloading your body. You don't just learn exercises, you understand why you do them.

Frequently asked questions
A session takes 60 minutes, fully one-on-one at Sportcity Heerenveen.
Yes. You pay for a package in advance, by invoice, and you're committed to it. Only for special reasons, such as moving or long-term illness, we make an exception. The intake and trial session are free, so you only decide afterwards whether and with which package you start.
No, you don't need a Sportcity membership for personal training.
This depends on your goals and availability. Most clients train 2-3x per week. You also get a program for independent training sessions.
Absolutely! That's exactly when guidance is valuable. We start with the basics and build up slowly. You learn the right techniques from day one.
As a physiotherapist, I can handle this perfectly. We adapt exercises and work specifically on strengthening weak spots.
