Some people say you need to be physically fit before you start taking martial arts classes (i.e. Karate), but some people say you take martial arts classes to become physically fit. There are many schools of thought. One thought believes that martial arts instruction should be up to the individuals’ desire to seek deep martial arts instruction, so the group classes are conducted with vigorous physical fitness exercises with small elements of martial arts techniques. The other school of thought believes that it is up to the individual to take initiative to conduct physical fitness training on their own time and that attending martial arts classes is for the main purpose of learning martial arts techniques. I think that both views are valid, what do you think?
