When you think of Grinder, you think of running, right? Lots and lots of Beast Mode running…like you check your watch at the end and realize you’ve done three and a half miles, mainly hills, in the past 45 minutes running. Not what you think when you think of Grinder? Best sleep in Monday, then. But, if you are ready to reimagine who I am, what you can be and challenge (perhaps even surprise?) yourself, then come out to the Silo Monday. It’ll be you v you and no man will be left where we found him.
