Some grapplers think that getting stronger will help their BJJ while others think that it doesn’t make much of a difference. The real question is, which group is right? Theoretically, being stronger should allow you to carry out moves more effectively in Jiu-Jitsu. However, common practice has showed that instead of focusing on proper technique, stronger grapplers try to “overpower” their opponents.
In some cases, they might even win a few matches or dominate at their academy simply by knowing a little technique and being the strongest. However, in the long run, this grappler will run into some problems when they move up in ranks and start grappling against higher belts. As you progress up the Jiu-Jitsu rankings ladder, strength becomes less and less important. By the time you’re a brown or black belt, it doesn’t really matter at all.
