This is the friendliest CrossFit box in Amsterdam. I really enjoyed working out there.

No experience needed. No programmes to figure out. No subscription quietly running on.
Sound familiar?
You already know you should move more. Knowledge isn't the problem.
The problem is a start that actually holds. Here's what stops people — and how it works here.
“I'm not fit enough to start this.”
Not being able to do a push-up, getting out of breath fast, feeling stiff or never having touched a barbell: none of that blocks you. The starting assessment sets your baseline and every movement is adjusted to it.
“I don't have time to figure this out too.”
You don't figure anything out. You get a concrete rhythm of 3 sessions a week, and in the starting assessment we pick the class times that fit your calendar.
“I've started before and it didn't stick.”
That's why there's a personal midway check. If you're at risk of dropping off, we adjust your plan instead of waiting for you to disappear.
“CrossFit looks intimidating.”
Everyone works on the same session with their own variation, weight and pace. The coaches know you're new and explain the class structure, the terms, the weights and the scaling.
What you're working towards
Where you stand after 28 days
No promises about kilos or centimetres — just what taking part seriously realistically gives you in four weeks.
Your first proof of progress
You start with an assessment and a Fit Test, and you finish with them. You compare yourself to your own baseline, not to an average.
Confidence in what your body can do
You experience how exercises, weights and pace get adjusted to your level. So you know you can train seriously without having to match anyone else.
A rhythm that fits your week
Fixed slots, planned in, with a group that expects you. 3 times a week is enough to notice the difference and doable alongside a busy job.
Fewer decisions to make
No programmes, weights or movements to pick. You walk in, the session is ready and a coach is watching.
Value from day one
You don't wait four weeks for something to happen
Every phase gives you something you can use that same week.
- Day 1
The starting assessment gives instant clarity
After one session you know where you stand, what's sensible and which classes suit you.
- Session 1
Your first win
Your first coached session is a real session — at your level, with a coach beside you.
- Week 1
Your rhythm is set
After the first week your training slots are in your calendar and you know how a class runs.
- Day 28
Final assessment and conversation
You see your progress in black and white and know which next step fits your week.
The programme
Four phases, not one long list of promises
You know up front exactly what happens, when, and what it gives you.
- 1Phase 1
Your Personal Starting Assessment
- Intake of up to 60 minutes
- Body measurement as your baseline: weight, body fat percentage, muscle mass and visceral fat

- Your goals, experience and calendar
- Choosing your classes together
Result: You know where you stand and how to start safely.

- 3Phase 3
The Midway Check

- We look at attendance, recovery and rhythm
- We adjust your planning if needed
- A short WhatsApp check or call if you're at risk of dropping off
Result: One busy week doesn't have to end your routine.
- 4Phase 4
Your Proof of Progress
- Final assessment: the same body measurement again
- The same Fit Test again, in your variation

About starting, coaching and the atmosphere

A box with great atmosphere and very professional trainers. Best of the best with a great quality of trainings and multiple available hours to choose for doing your WOD throughout the day.

Start my 28 days — €99
12 sessions · personal guidance · no membership
Honest maths
12 single sessions cost €20 each here: €240 in total. The starting assessment, the personal coaching and the bonuses come on top of that in this package.
You pay €99 once.
Why this is so accessible
We deliberately make the first 28 days accessible, because a membership only has value once you know how to begin and have found a rhythm that fits your life. So we invest in a good start first — without tying you to a long contract up front.
After this form you pay through our booking system. No subscription starts — this is a one-off payment for your Strong Start.
Included bonuses
Four extras that remove the usual stumbling blocks
No filler: each bonus answers a real reason people drop off.
- Bonus 1
The Busy-Week Plan
Your preferred classes, concrete alternatives and a minimum option for exceptionally busy weeks.
For: “My calendar fills up.”
- Bonus 2
Yoga recovery class
One class at Yoga Zeeburg for recovery, mobility and letting go.
For: “I'm afraid I'll just end up stiff.”
- Bonus 3
First-Week Certainty
The coaches know you're new and give extra explanation about class structure, terms, weights and scaling.
For: “I won't know what to do.”
- Bonus 4
Bring-a-Friend class
During your 28 days you train one suitable class together with someone you bring along.
For: “Starting alone feels daunting.”
Risk reversed
You bring the effort. We take responsibility for the start.
We don't promise miracles. We do promise that taking part seriously here gets measured and doesn't end without a next step.
Promise 1
The Strong Start Promise
The condition: you attend at least 10 of your 12 sessions and take part in both assessments, at the start and at the finish.
Assessment one is a body measurement: weight, body fat percentage, muscle mass and visceral fat. Assessment two is the benchmark WOD: a 500 m row, 40 air squats, 30 sit-ups, 20 push-ups and 10 pull-ups for time, with variations adjusted to your level.
Only when neither assessment shows any measurable improvement do you receive €50 in SportBit credit. Improvement on at least one assessment counts as a result — then the promise does not apply.
You show commitment to your start. We take the risk of no measurable improvement off your shoulders.
The €50 credit is automatically deducted from your next purchase at CrossFit Zeeburg and is never paid out in cash.
Promise 2
Continuing? Then your Strong Start is deducted
Take a CrossFit membership within 7 days of your Strong Start ending and we deduct a credit from your first payment: €99 with a minimum term of 12 months, or €45 with a minimum term of 6 months.
You only make that choice after the 28 days. During your Strong Start there is no membership obligation.
You commit to your start. If you continue, we invest that amount straight back into what comes next.
Conditions
- €99 for a CrossFit membership with a minimum term of 12 months
- €45 for a CrossFit membership with a minimum term of 6 months
- Taken within 7 days of your Strong Start ending
- It is a credit we deduct, not a cash payout
- Not transferable and not combinable with other starter discounts
Availability
A maximum of 3 new Strong Starts per week
That isn't a sales trick, it's a practical limit. Every start costs us real time:
- a personal intake of up to 60 minutes
- preparation by the coach who guides you
- measurements and a Fit Test at the start and the finish
- a personal results conversation
If a week is full, you simply take the next available start week.
Straight talk
Who this is and isn't for
Better clear beforehand than disappointed afterwards.
This is for you if
- you're a beginner or restarter who wants to take it seriously
- you're willing to come 3 times a week
- you want coaching instead of figuring it out yourself
- you want to know what actually changed, not guess
This isn't for you if
- you want to drop in now and then without commitment — take a single class instead
- you're looking for medical treatment — that belongs with a doctor or physiotherapist
- you're not willing to train an average of 3 times a week for 4 weeks — a more flexible entry route suits you better then
