Chris Robinson demonstrates an insanely intense complex of exercises on the Cadillac, aimed at building mental stamina. It's a physical challenge like this one that Chris carefully develops over time in the athletes he trains with the goal of helping them perform under pressure. You'll see that even as the series becomes more and more difficult, Chris works to maintain a calm, steady state and to not freak out. Keeping your mental state calm and disconnected from chaos is something we can all use more of, try it out! Visit Chris at S6 Fitness.
