@Caleb Turner I agree conditioning should be its own thing. And that technique as in karate or wu shu teachnique should be separated when training. However, I am a firm believer in a martial art teacher teaching and correcting his students form when it comes to the exercises I showed pictures of. Not everyone is an athlete. And people take time away from their training. Or may get hurt. This is when having a teacher teach you these skills is key. Youtube videos are fine. And some students of martial arts may cross train at a weight lifting gym or health club. But it has been my experience most people cannot afford to pay to train at multiple places. So, they try to get the most out of training where they can. If this means skipping martial arts they will in favor of other exercise. So, in order to prevent that from happening why not have exercise as a part of the classes. Even if you have to set aside the first 20 minutes to teach stretches. Then go over conditioning exercises like push ups, jumping jacks, sit ups. This would help increase performance. And it would prevent injuries. As we all know lots of people hurt their necks when starting to do sit ups or crunches. This inclusion in martial art classes of the proper conditioning exercises would prevent that big time!
