GSU competition rule. Athlete Classification category.
The addition of intermediate kettlebell weights is the key differentiator between GSU and its parent IUKL system. Standard IUKL uses 16/24/32kg for men and 8/16/24kg for women. GSU adds 20kg and 28kg for men, and 12kg, 20kg, and 28kg for women. This allows athletes who are not ready for the next standard weight to still compete and rank at a weight that challenges them, promoting development and retention.
