Brazilian Jujitsu is an art that one can practice for hours, just playing with it. In Aikido practice, the defender usually knows what attack is coming. Once students learn the fundamental techniques, we tell them just to go for it - to try anything on us without holding back. That's why I said earlier that, if we want to introduce something into Aikido to give people a warrior spirit, we should do the grappling. It's a phenomenal workout.
