With head coach Mike Krzyzewski busy preparing Team USA for the 2016 Summer Olympics and a long, grueling summer of off-season workouts coming to a close, Duke basketball decided to step outside the box for some conditioning work. Instead of running suicides or sprints, the guys did something totally different: launch red balls at each other as hard as they could.

Objectively, dodgeball is one of the best in-the-gym games athletes can play. It has legitimate conditioning benefits. It requires quick reaction time—the ability to move laterally to avoid being hit in the chest and having your wind knocked out of you, and the ability to stop on a dime. If your heart rate isn’t up when the game is finished, you’re definitely that kid who hides in the corner until everyone else is eliminated. No one likes that kid.

Since Coach K hates fun, dodgeball will probably end once he returns from Rio. But for now, Duke has managed to knock conditioning a little further down the list of worst workouts ever.
