One Diameter, Nine Weights
Every ball is 14 inches across, whether it weighs 6 lb or 30. Scaling up changes the challenge, not the mechanics of the catch. Consistency is the feature.
Built to Stay Round
High quality construction holds shape through daily impacts against walls and floors, instead of slowly turning into a lopsided bean bag. Shape retention is the whole game.
A Grip You Can Trust
The textured surface holds firm through sweaty high rep sets, keeping your throws accurate and catches confident deep into a conditioning piece, right when it matters most.
Core Work and Cardio
Wall balls, slams into throws, twists, weighted sit ups, partner passes. One ball covers strength, stabilization, and lung burning conditioning at once. One tool, many jobs.
