You have to get used to tapping out to learn Jiu Jitsu or you are going to pay the price in your joints and muscles. The first step to learning the art is to tap your ego. Remember the most important part of training is getting tapped out. You should always seek to train with people better than you who can tap you. Tap easy, tap often, and always say thank you and shake hands with your training partner after you tap in a roll session. Please don’t resist your training partner or be hard to tap when they are learning a move. When we are drilling and rolling we put on joint locks SLOWLY. It takes time to learn Jiu Jitsu; we need to keep ourselves and our training partners in the game long enough to get good. 

The way people learn the most effectively is starting off completely relaxed and just memorizing the position and doing repetitions of getting into and out of it, at first with no resistance, then very, very gradually increasing resistance from the training partner until they can do the move against live resistance. This is called “Progressive Resistance Methodology”.
