BOLT's volume-based scoring (IVSS) rewards total work capacity rather than just rep count. An athlete who chooses a heavier bell and does fewer reps may score higher than one who uses a lighter bell with more reps. This encourages progressive overload and rewards strength alongside endurance. Traditional Girevoy Sport scores purely on repetition count with prescribed kettlebell weights.
