Develop strength and coordination with this slam ball for beginners and familiarize your students to traditional medicine balls with a great introduction. 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 designed specifically for beginners allow students to get a great grip to perform 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. The 7” dia fits well in smaller hands, and paired with the lighter weight (just 6 lb), gives students confidence as they focus on proper form.

Sand-filled slam balls shift and create instability in a student’s hand. The simplicity of this equipment, yet the effectiveness of its training options, makes it a wonderful introduction to strength training and coordination. Students will need to engage their core to maintain each movement.


  • 7" dia, 6 lb ball effectively introduces students to strength training with brightly-colored equipment, designed just for them.
  • Laminated activity guide shows 6 slam ball exercises to use with beginner students. No research is required to provide thorough instruction to your students! Exercises focus on strength and body awareness, as well as coordination.
