The Gross

The beauty of this workout is that you can adjust the intensity based on the level of pain you want to inflict. Pick 12 exercises and perform 12 reps of each. That’s 12x12=144, which is known as a Gross. This workout was first done by Barry Manilow and YHC to showcase the exercises we hate the most, all in one session. It’s guaranteed to generate fantastic mumble chatter.
