Their small size, unintimidating feel, and bright coloring make them approachable, giving students the confidence to learn slam movements of all types.

Ideal for Beginners

Our only slam ball for beginners, students will easily get a great grip on these balls when engaging in drills such as overhead slams, med ball chops, or other slam-based movements. The cover features unique molded channels that make gripping and handling ergonomic and simple, allowing for more control during fast-paced slams, throws, and catches. It’s also extremely thick for additional durability in the face of uncertain handling by beginners.

The 7” dia size of balls is also great for smaller hands, giving students confidence as they learn the basics of training. Control will be steadier as new movements are introduced, building comfort with slam balls that will translate to future training with more advanced equipment.

Great Training Option
