4-Sided Rubber Dumbbells

Length: 5.8in (147mm)
Diameter: 1.25in (32mm)

When it comes to dumbbells, rubber and urethane dominate for a reason—but there’s a difference in performance. Urethane stands out with unmatched durability, resisting abrasions and maintaining its look through intense use and time. While it comes at a higher price, urethane delivers premium performance, built to handle the grind of elite training environments and the toughest workouts.

Yes, our Dumbbells all have a warranty.  See the warranty page for specifics.

New dumbbells may have a light protective oil coating to ensure they arrive in top condition. This coating will naturally wear off after a few weeks of use, but you can speed up the process by wiping them down with a dry rag. Rest assured, they’re ready to perform from day one.

Rubber dumbbells naturally have a slight odor, unlike urethane, which is virtually odorless. However, Hammer Strength uses premium rubber materials designed to minimize smell without compromising durability or quality, ensuring a top-tier training experience.
