Strength starts with movement

Everyone benefits from strength training

Want to keep playing with your kids, hiking in the mountains or playing tennis with friends? Strength training helps you do that. It doesn't mean living in the gym. A solid base of strength simply pays off in everything else you do.

But good movement comes first. When your mobility, stability or symmetry is off, another part of your body takes over. Knee pain, for example, doesn't always start in the knee. It can come from an ankle or hip that doesn't move as well as it should. That's why every client starts with a movement screen. Then we pick the exercises your body needs most, and build strength on top of that.

As long as you are mobile and symmetrical, strength has to be your priority.

My approach

movement screen
Step 1

Analysis of how you move

The movement screen shows me how your body moves. What works well, and what to pay attention to before we start loading your body.

Step 2

8 weeks of training

Classes of an hour, twice a week. Everybody does the same full body workout, with exercises adjusted to your personal needs.

evaluation and plan
Step 3

Retest and recalibrate

After 8 weeks we test again: the movement screen, or a fitness test once your movement is in order. We look at what has improved and set the focus for the next 8 weeks.

About me

Hi, I'm Sietse

I'm 32. I started going to the gym when I was 18, and I've been into health and sport ever since. I've been a personal trainer for about a year now.

During my studies I had a teaching job, and I found out I love teaching: finding the missing piece that takes someone from not understanding to understanding. Movement works the same way. What's the missing piece that helps someone move better?

After my studies I moved to Australia, right before COVID, and worked outdoors in construction. I realised I didn't want a life behind a screen. It all came together: I have a good day when I've helped someone, I love teaching, and health and sport have always been part of my life.
