Complete the setup

Add the matching workout bench — opens up presses, rows, split squats.

CINQ Compact Weight Bench
How it works

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

Load the plates you want onto the handle, spin the adjustment nut tight, lift. The threaded steel collar bites the bar so the plates can't shift mid-set — no wobble, no slip, no rerack.

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 collar — 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.

★★★★★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 dial feels like a watch crown — there’s a satisfying click between each setting.

★★★★★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.

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.

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.

Questions

What everyone asks.

Will the 25 lb top end ever feel light?
For most people doing 20-minute strength sessions at home — no. The 25 lb top end paired with tempo, time-under-tension, and pause work is enough stimulus to keep building muscle for years. Heavy lifters who want progressive overload above 25 lb should look at our forthcoming 50 lb stack.
How loud is it on a hardwood floor?
Quiet. The threaded steel collar locks the plates flush against each other — no rattle mid-rep, no clack between sets. Most customers say it’s quieter than setting down a coffee mug.
What if it breaks?
We replace it. Forever. One email, no receipt needed. Made in Columbus, Ohio with a steel-only load path so there’s very little to fail in the first place.
How is it $149.99 when the others are $400+?
We sell direct, batch-produce in small runs, and don’t pay retail markup or storefront rent. The price you pay is roughly 1.4× our cost, not 4×.
Can I try it first?
Yes — 30-day home trial. Use it for a month; if it doesn’t earn its space we send a return label and refund in full. No restocking fee.
Does it come fully assembled?
Out of the box and lifting in under five minutes. The handle, dial, and base ship pre-assembled. You just place the base wherever it’s going to live.
