This set of dumbbells can be combined into a barbell in one step using a connecting rod; no additional purchase is required. Adjustable cast iron dumbbells can be used with a weight bench for shoulder and chest training. 

Extended Strength Training

A adjustable dumbbell set can meet family needs and different weight needs from children to parents. Our adjustable dumbbells with a dumbbell connector offer great versatility and interchangeability. You can easily tweak your training levels or switch between working out with dumbbells or barbells. 

Craft Manufacturering

The box dumbbells piece adopts the casting process and is integrally formed, resistant to falling and durable. The electroplating process makes the cast iron dumbbells less rusty and more durable.

Unique Design

Our iron dumbbells are smaller and heavier than concrete dumbbells. A thicker nut and an upgraded nut lock design are used, making it more compact and reducing noise. The handle adopts an ergonomic design and non-slip particles, which is more comfortable to use and non-slip.
