IKLF competition rule. Competition Format & Structure category.
In BOLT, athletes choose their own kettlebell weight for competition. This is a fundamental difference from traditional Girevoy Sport, which prescribes kettlebell weights per rank level and gender. Any kettlebell weight can be used, but a minimum kettlebell weight is required for each rank level. Heavier kettlebell choice results in a higher base volume score.
