Kassy is wearing boxing wraps while Alyson is wearing gloves. They go at it to find out who can take more punches to the stomach.
These girls take it very seriously. They go at it hard, to the best of their ability. They take turns of throwing one or two punches and then brace for the incoming. As they tire they need more and more time to recover between punches. If they get on the ground the other can punch them freely until they get back up or quit.
