Forms may be integral to SOME martial arts, but they are not integral to all. And I'll go back to my own forms. There isn't a deeper level to them. I linked together some movements to give folks an exercise they can repeat to work on fluid movement, balance, light cardio, etc. They aren't deep teaching tools. If someone removed them entirely from the system, it wouldn't leave a gap of any kind, assuming they help people in those areas with other exercises.The problem with this ideology is that there are schools that do not train in application. They train on how to use form and sparring technique for best use in competition.
Do you learn the form? Yes.
Do you learn to spar? Yes.
Do you learn to protect your self or a loved one in the event of an attack? Assuming average strength and no other training, Unlikely.
Do you learn avoidance or situational awareness? No
Do you learn philosophy or historic value? Unlikely
Forms are integral to MA and Must include application to have value beyond the improved physical condition benefit.
