Rubber hex dumbbells are the workhorse of a home gym, and these are PRx Performance's own. Six sided rubber heads protect your floor and stop the roll, chrome plated knurled handles keep your grip secure, and pairs run from 3 lb all the way to 100 lb so you buy exactly the weights you train with.

Genuine PRx Performance
Synergy Custom Fitness is a PRx Performance retail partner. Every PRx free weight on our site is the same gear PRx sells directly, fulfilled and shipped to your door by PRx itself.
Six Sided, Stays Put
The hex shape is not decoration. Set the dumbbells down mid circuit and they stay exactly where you put them instead of rolling toward your ankles or under equipment.
Floor Friendly Rubber
Rubber coated heads take the sting out of every set you put down. They are quieter than bare iron and far gentler on garage concrete and gym flooring.
A Grip That Works
Slightly arched, chrome plated, knurled handles follow the natural line of your palm. Handle diameter is 25mm through 12 lb and 34mm from 15 lb up, with a 5 inch grip length.
Every Weight, Sold in Pairs
Twenty weight options from 3 lb to 100 lb, each sold as a pair. Start with the weights you actually use today and add heavier pairs as you get stronger.
Genuine PRx, Shipped Direct
