One of our largest clients asked us to make a ball that would take abuse of hitting j-cups on a rig and not rip open. Well, we've done it. Additionally, we've used the same RAGE Fitness quality standard of over stuffing our ball so it doesn't soften over time and roll testing each one to ensure its balanced during use. Rest assured this ballistic medicine ball will be a staple fitness item in your home, club or studio for years to come.
