Just two size requirements

Your dumbbell handle length must be at least 4.5” long to accommodate the width of the Hyperbell Bar clamps. (Most are 6”.) Lastly, the diameter of your dumbbell handle can be no bigger than 1.5” at its thickest point.

Easy to use

Innovative adjustable clamps easily convert dumbbells into a barbell. Attaches quickly, allowing a moment to recover while resetting between sets.

Maximize the gear you already own

Like all Jayflex products, the Hyperbell Platform is intentionally designed to take up very little space, and to maximize the gear you already own, saving you from buying a bunch of big, bulky equipment that clutters up your home and takes a bite out of your wallet.

While giving you a substantially more varied workout than your dumbbells alone can provide. (Pro tip: Challenge yourself even further by adding Hyperbell Resistance Bands to your Hyperbell fitness regimen.)

Too expensive

Too expensive for what it is.
I got a box that was obviously a return from someone else. The box was ripped open and taped back together. Too lazy to a return.

Clamp lock

When I first got the curl bar I love how it look! I was so excited to get started. I have the boflex dumbbell and it was a challenge holding down the clamp to screw the lock. By the time I got it to secure my hand was in so much pain. Then I realize I was setting up for tomorrow work out! If it weren’t for the hard to secure I would have gave it 5 star.

Great invention

Perfect for a small condo gym that doesn’t want to buy a ton of equipment. Now I can do what I need to do.

Worth the purchase!!

Fits multiple dumbells. It is tight and secure. It is versatile, and I highly recommend it.
