For Jiu Jitsu, 3 days a week is maintenance and training more is for improvement. The reality is you can probably take 3 hours out of your 168 hour week to train. If you work 40 hours, sleep 56 hours and train BJJ 3 hours a week that still leaves you with almost 70 hours for other things. So if your goal is to be better at grappling, is what you’re doing with your extra 72 hours serving that goal? If you come in and say I want to be better at this, I can do that, if you put the work in. I can’t help you reach your goals, if you’re not putting in the effort. Minimal effort in BJJ is 3 days a week, that’s training as a hobbyist and the long road to a black belt. These 4 year black belts might have been talented, but they also lived in the gym, they were dedicated to only getting better at Jiu-Jitsu. You can’t hold yourself to that standard and you can’t hold your coaches to that standard. If you’re in the gym 5-6 hours a day, every day, all year round, that’s when you are measuring yourself against those people correctly. There is no immediate gratification in BJJ and there’s even less so when you’re not putting in the effort to match your expectations. There’s two ways to go with that information, either lower your expectations of yourself or raise your standards for yourself.
