Jiu jitsu is all about the little guy defeating the big guy but nobody can turn away when a 300 lbs powerlifter starts training in the academy…
In the past, there have been many instances where strength athletes, whether bodybuilders or powerlifters, have tried training Jiu-Jitsu and have rolled with the instructor to test themselves:
Bodybuilder Has an Intro Class Then Takes On a BJJ Black Belt
Another one that comes to mind was when a BJJ practitioner and a bodybuilder tested each other in a specific strength competition:
Bodybuilder & BJJ Practitioner: Specific Strength Competition
In this instance we 2 have two marines that are grappling on concrete. On one side, we have a 140 lbs BJJ blue belt who happens to learn online from Gracie University and a 205 lbs Marine wrestler.
