Street Workout Ultimate Battles (SWUB) started in 2017 in Spain, created by Jordan Bioco and his team. It runs as a 1v1 knockout tournament where athletes compete in dynamics, statics, and power moves, scored by a panel of judges.

Brackets go from a first round through quarter-finals, semi-finals, and finals. Judges score each battle on execution, difficulty, creativity, and variety. A women’s bracket was added at SWUB IV in 2022 and has run every edition since.
