The dumbbell, a type of free weight, is a piece of equipment used in weight training. It can be used individually or in pairs, with one in each hand.

How much weight can you put on adjustable dumbbells?

These highly versatile adjustable dumbbells can be set at 5 to 50 pounds per hand. When you're ready to advance further there are add-on kits to increase the weight to 70 and 90 pounds on each dumbbell.

Standard (1-inch center hole) plates are commonly available in 2.5, 5, 10, 25, 35 and 50 lb denominations, with 1.25, 7.5, 12.5, 20, and 100 pound plates less commonly seen.

Each handle is compatible with any standard 1-inch weight plate and can accommodate weight plates of 2.5 to 40 lbs. Each bar measures 14 inches long, 3 inches wide, and 3 inches high.
