Perfectly balanced and durably constructed, our Elite Power Med-Balls are guaranteed to maintain their shape. Perform traditional medicine ball exercises, bounce them against a wall or floor, or pass them to a partner or rebounder. The textured surface, of these medicine balls, ensures superior grip and handling. Incorporate them into any group fitness, sport-specific, or rehabilitation movement for added resistance. Hollow synthetic rubber construction allows med balls (aka medballs or medicineballs) to bounce. 3-year limited warranty.
