The whole body of the dumbbell is forged in cast iron. No plastic or fragile parts ensure the dumbbell does not break even if dropped from a height. The 50lb dumbbell set (each dumbbell: 11.2"L x 7.2"W x 7.2"H with a 6.8" handle) is adjustable — simply unscrew both ends to unlock, add or remove plates, and screw them back tight.
The Adjustable Dumbbell Set is ideal for fitness enthusiasts and strength-training beginners who want to start gradually and systematically increasing resistance.
