How to set up (30s)

Three quick moves — on and ready in about half a minute.

1 Unscrew & open the clamps

Twist the knobs to release and fully open both sides. No tools needed — start with a clear, open clamp so loading is effortless.

2 Add your dumbbells

Slide each handle into place, then center them using the balance markers. Most common dumbbell handles fit — go for an even, comfortable feel.

3 Tighten the clamps

Turn until snug for a play-free hold. Do a quick shake test, then begin with conservative loads and build up as you get comfortable.

Why OJEXA vs a bulky barbell?

Space-smart by design. Get bar-style movements without dedicating a whole corner to a rack and full-length bar.

Fast to set up. Clamp, align, lock — you're training in seconds, not minutes.

Comfort & control. Steel lock collars, precision balance markers, and a cushioned grip keep lifts feeling secure.

Setup: Seconds

Once familiar, you're under the bar faster than with plates and collars on a long bar.

Compact Footprint

Ideal for apartments and small home gyms. Store it in a drawer or on a shelf.

Versatile Lifts

Bench-style, rows, curls, RDLs and more — without the full barbell overhead.

Aspect Traditional Barbell OJEXA
Setup time Longer (plates + collars) Seconds (clamp & lock)
Footprint at home Large (bar + rack) Compact (drawer/shelf)
Cost of entry Higher (bar, plates, rack) Lower (use dumbbells you own)
Exercise variety Excellent Bar-style variety, home-friendly

Notes: Always train responsibly. Max load depends on your dumbbells, assembly, and exercise selection.

From the founders

We're two friends who lift in small spaces. A full rack didn't fit our lives—and the "converters" we tried were slow, loose, or uncomfortable. So we built our own.

After months of prototypes, clamp tests, and false starts, OJEXA clicked: steel lock collars for a confident hold, precision markers to keep both sides even, and a cushioned grip you actually want to use. It sets up fast, stores small, and makes bar-style training possible at home.
