Same old warm up? Try this random technique, now drill and let's roll. Is this the best way to learn? Probably not. Even though every Jiu-Jitsu coach has a different approach to teaching technique, the current state of BJJ classes is a tired old formula.
But what is the best way to teach BJJ?
If you are struggling with remembering what is taught in class you need to find the best way for you to learn. Once you identify what works this it will accelerate your BJJ dramatically. The way the class is taught is outside your control so don't depend on it, be intentional and own what you are learning.
