Gary, you would have to explain to me what you mean by body conditioning. Health is one form. Fitness is another. Suppleness is another. What conditioning are you referring to?
If one was wanting to run a 2:10 marathon...... the body needs to be conditioned to carry the spirit and the mind on the run.....otherwise it won't happen..... To do do any Aikido the body has to be able to carry the spirit and mind.....
