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.)

Problem solver!

I had been working out with dumbbells only for a while but missed using an EZ bar for arms. I was just about to invest in one and some plates when I saw this ad for the Jayflex bar- problem solved! No additional weights to buy just clamp the dumbbells to the bar and go! Bar and clamping system work great. I’m thinking about getting the straight bar now..

Love it?

The curl bar and barbell are the perfect addition to my small home gym. I was considering purchasing a rack of weights before discovering your product. So glad I found the jayflex products first!
