That's the best drill in the world for learning control. My kids and I study aikido and having them pounce on me en masse is a great way to work locks and make sure the technique is correct. If the tech is off I'd have to try to muscle it and they would get hurt, if the technique is correct I can get it locked in with just enough pressure to stop their motion. At the same time they are allowed to use as much energy on me as they want just to show them that strength/force does not always equal proper technique.I wouldn't say that...have you ever been attacked by 5 kids at once? There is definitely improvement there in your MA abilities. Try suppressing all of them at once, without hurting them! Quite a chore
