Founders' Edition · First 500

Strength that fits next to the couch.

Plates you stack by hand. A spin-collar that locks them firm. Smooth transitions, zero wobble, no rack between sets.

Why CINQ

One piece. Three reasons it earns its space.

01

Built to live with you

Walnut base, blackened steel, plates the colour of cast iron. It earns its spot next to the bookshelf — not banished to the garage.

02

Locks. Never wobbles.

A threaded steel collar bites the bar so the plates can’t shift mid-rep. Hand-tight in under ten seconds. No tools, no clatter, no second-guessing.

03

Buy it once

Forged in Columbus, Ohio. Lifetime no-fail warranty — if it ever breaks, one email, no receipt needed. We replace it. Forever.

CINQ Adjustable Dumbbells
The 5-in-1 adjustable dumbbell

How it works

Stack. Spin to lock. That’s the whole workout.

Load the plates you want, spin the adjustment nut tight, lift. The threaded steel collar bites the bar so the plates can’t shift mid-set.

Step 01

Stack

Slide the plates you want onto the handle. 5 lb increments — load up exactly what the set calls for.

Step 02

Spin to lock

Hand-tighten the adjustment nut against the plates. Threaded steel — no rattle, no drift, no spotter required.

Step 03

Lift

Smooth handling, balanced load. To switch weight, spin off, swap plates, spin back on — under ten seconds, every time.

In real homes

Built to live in the room you already live in.

Not the basement. Not the garage. The corner by the window, the side of the couch, the foot of the bed. This is the home-gym piece that doesn’t look like one.

★★★★★Daily lifter
I’ve owned a Bowflex, a PowerBlock, and a rack of cheap fixed dumbbells. The cinq is the first one I actually use every morning. Two seconds to switch, no clatter, no excuses.

★★★★★Small apartment
Lives next to my bookshelf. Doesn’t look like a gym thing. The spin-collar feels like a watch crown — there’s a satisfying click when it locks.

★★★★★Heavy user
Asked it to do RDLs at 25 lb three days a week for four months. Still tracks straight, still rotates clean. The handle knurling is the right amount of aggressive.

A note from the founder

The gym I wanted didn’t exist.

So we built a single, beautiful piece — something that earns its space in a small apartment, that doesn’t feel like compromise, that you reach for first thing in the morning instead of stepping around.

If it ever fails you, write us. We’ll replace it. Forever.
