A box, not a gym
At ZÍU BOX you will not find rows of machines or screens. You will find barbells, kettlebells, ropes and a coach who knows your name. We train the movements you use every day: lift, push, pull, run. Every class scales to your level, so the same workout works for someone starting today and for someone three years in.
Small groups
Twelve people per class at most. The coach sees everyone and corrects everyone.
No experience needed
Week one is technique. You learn to move before you load weight.
Everything scales
Same workout, different load. Nobody sits out a class here.
A real community
You start as a group and finish as a group. That is what brings people back.

Frequently asked questions
Do I need to be fit to start?
No. Most people arrive having never trained. Week one is technique and light loads, and every movement scales to your level. The coach adjusts the workout to what you can do today.
What do I bring to my first class?
Comfortable clothes, flat soled shoes, a water bottle and a towel. That is it. If you have an injury or a medical condition, tell the coach before you start.
Do I have to book or can I just show up?
Booking on WhatsApp is better because groups cap at 12 people. Spots open 24 hours before each class.
Is there a contract or minimum term?
No contract and no sign up fee. You pay for the month and if you do not want to continue, you stop. The quarterly plan is a prepayment discount, not a commitment.
Can I come only a few days a week?
Yes. The monthly plan is unlimited, so you come on the days that work for you. If you plan to train two or three times a week, drop-in may work out cheaper.
Do you accept SINPE Móvil?
Yes. You can pay by SINPE Móvil, bank transfer or cash at the box.
