About us

Real technicians,
not a call center

CJ Fitness was built by hand, not from an office. We're specialist fitness equipment technicians with over a decade repairing, installing and maintaining machines for gyms, companies and homes across Spain.

We started out repairing machines at neighborhood gyms in Madrid, back when most multi-brand technical service depended on shipping parts and technicians in from outside the country. Over the years that work grew into a company with its own team, able to cover everything from a one-off repair to the full assembly of a 1,000 m² gym.

Today we still work the same way we did on day one: we take the call, go see the machine, and fix it with real parts. The difference is that now we do it for gym chains, hotels, residential communities and individuals across Spain, with a team trained by the leading brands in the industry.

We don't outsource diagnosis or subcontract repairs: the technician who takes your call is, almost always, the same one who shows up to fix your machine.

How we work

  • Hands before phone

    We'd rather see the machine than guess a diagnosis over the phone.

  • Real parts

    Original or certified equivalents. Never generic parts of dubious origin.

  • One point of contact

    The person who quotes the job is the same one who does it.

  • No surprises on the invoice

    The quote you sign is what you pay, unless something new comes up — and we'll tell you before we act on it.

The workshop, as it really is

No studio poses: this is what our real work looks like in gyms, boxes and fitness rooms.
