FAQ

The number molded into the inside of each dumbbell head represents the pound (lb) equivalent of the weight. This is helpful for accommodating different user preferences, ensuring quick identification, and making transitions between sets smooth and efficient. 
When it comes to finding the best dumbbells, urethane and rubber dumbbells 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 functional strength training workouts. 
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. 
Our 4-Sided dumbbells cannot be customized at this time.
