Calisthenics,structured.

TENSION builds custom calisthenics structures — one bar, a backyard rig, a civic park. You configure it on screen: pick modules, see the price and dimensions live, watch the scale figures land. We weld it and ship it.

N° 02 — Manifesto

We weld the bar.
You bend the body 
until both are honest.

Principle / 01

Every build is fabricated on order. No off-the-shelf flatpacks. We cut, weld, galvanize and ship from a single Bucharest workshop.

Principle / 02

You configure the structure on screen — modules, dimensions, finish — and the price moves with you. No back-and-forth, no opaque quotes.

Principle / 03

Built to outlive a generation. EN 1176-rated steel, galvanized or stainless. Public parks come with anchor docs and warranty.

N° 03 — Catalog

Six families.
Twenty modules.

Every build is composed from a single catalog. Pick what you need, drop what you don’t.

F-01 · Pull family

Single bars, double-height, 3-station rigs, gymnastic high bar. The spine of every build.
