Twelve weeks to regain control.
Google Review with 4.5 stars
Why previous attempts did not stick
You often know exactly what is healthy. But knowing is different from doing.

You start strong, but alone
The first week goes well. After that, the external accountability disappears, and choosing health becomes dependent on motivation again.

You focus on a single component
Focusing only on training, only on nutrition, or only on mindset is often too narrow. Your life works as a whole; your approach must do the same.

You have no moments for adjustment
When things get busy, you need someone to look over your shoulder. Not to make you dependent, but to teach you how to correct your course.

Not alone, but personal
The group provides energy. The coaching makes it personal.
One of the strongest elements of I DO is the combination of group energy and personal attention. You train with people who are also on their journey. This makes it easier to show up, stay honest, and persevere. At the same time, your program is not generic: your coach looks at your goals, your patterns, and your progress. This way, you get support from the group without getting lost in the crowd.
You see others working, growing, and persevering. This normalizes the process and makes sustaining it more human.
Your coach helps you reflect, make choices, and adjust when old patterns resurface.

Personal intake
We do not start by talking. We start by listening.
During the intake, we discuss where you are now, what you want to change, and whether I DO is the right path for you. Sometimes the program is exactly what you need. Sometimes Personal Training, COMMIT FIT, or Business coaching is a better fit. The intake is intended to honestly determine what will best help you achieve the results you have in mind.
- An honest conversation about whether I DO fits you and whether we fit you
- Suitable for every level, including beginners
- We will contact you within 24 hours
- In 12 weeks, the power to make the right choices yourself
Mathijs on the I DO Program at COMMIT Utrecht
When the plan fits your life, sustaining it becomes possible.
I had already tried everything: periods of fanatical training, eating healthier, then falling back again. In the I DO Program, I received real structure for the first time. Not just a schedule, but guidance on my training, nutrition, choices, and weekly rhythm. After 12 weeks, I didn’t just know what I had to do, but especially how to maintain it.

After I DO · deepening and securing
Do you want to continue immediately after I DO?
Discuss during your intake whether I AM aligns with your goals. Some participants choose to combine I DO and I AM immediately, so that the first 12 weeks are directly followed by an in-depth quarterly structure.

Continue your progress with I AM
After the I DO Program, you can progress at COMMIT to I AM: an exclusive follow-up program where you continue to work on your physical and mental development. In a small, familiar group, you train twice a week, receive weekly coaching from your own coach, and delve deeper into themes such as self-leadership, mental strength, relationships, and sustainable behavioral change.
I AM is intended for those who do not want their results from I DO to fade away, but rather want to secure them for the long term. You continue to build on structure, energy, mindset, and ownership. With the support of a coach and a group that shares the same commitment.
Are you combining I DO and I AM immediately? Then an attractive package benefit may apply.
Who is I AM for?
I AM is the logical next step when you feel after I DO that you want to go further. Not because you cannot do it without guidance, but because you know how much stronger you become with structure, coaching, and the right people around you.
The program is right for you when:
- you do not want your results from I DO to fade away
- you want to continue combining mental and physical development
- you thrive on fixed appointments, group training, and personal coaching
- you notice that sustainable change requires more than just training
- you are ready to make health a permanent part of your life
