Across the full range — 3kg, 4kg, 5kg, 6kg, 7kg, 8kg, 9kg, 10kg, 12kg, 15kg, 18kg, 20kg, and 25kg — each slam ball is designed with a diameter that grows progressively with its weight. The lighter balls maintain a compact, easy-to-maneuver shape ideal for speed work, while the heavier models feature a broader, more substantial diameter that enhances control during high-power slams. This gradual size increase ensures every weight feels balanced and ergonomic for its intended training intensity.
