On this episode of the podcast, we are joined by BJJ Black Belts GW and John from “Grapple Science.”

GW and John are the co-founders of “Grapple Science,” a supplement company to help with performance for grapplers. GW and John discuss how they started in BJJ, how their BJJ games have evolved and changed since they have gotten older, the benefits of competition for older grapplers, why GW avoided training in the Gi when he first started BJJ to initially to now only training in the Gi, whether Gi or No-Gi is easier for older grapplers, how John and GW met and started working together at a company called “Kill Cliff,” the idea behind starting “Grappling Science,” the concept behind the “Grapple Science Cognition” nootropic for improved focus for grapplers, the feedback people have reported on the benefits of the “Cognition” supplement, and how caffeine can decrease performance.
