Depends whether you're learning martial arts or going to knitting classes (j/k) Some classes have a high degree of discipline. Nothing wrong with doing pushups either. Most students are paying to learn - many kids are sent along to learn discipline. Its important for the instructor to have a variety of behaviour-management strategies. In any case, pushups work well for adults too. Discipline helps focus and maximises the learning process. Remember as well that most attackers will not be in a joking mood, so its probably a good thing to train under some degree of duress. Yes indeed. Some of them prefer squat-kicks, sumo stance or burpees.. :D:D
