My believe is completely the opposite.Further to that by sparring early, because begginers dont know how to move, dont have the right reflexes, strength, speed etc. They can develop bad habits, wrong reactions which end up being a set back later on when you do learn to apply it all correctly.
I had my sparring in very early stage. Our sparring was one person played offense while another person played defense. While I was playing defense, I had to
- move my head to dodge my opponent's punches.
- use footwork to control the distance.
I had learned "head dodging" and "footwork" in my sparring during the first day. I have seen many of my classmates who didn't spar early. They had built "bad habit" by "not knowing" how to
- move their head away from their opponent's punches, and
- use footwork to move their body out of their opponent's attacking path.
The funny thing was when I started to train forms, I just could not find any form that has "head dodging". Can you learn "head dodging" through solo form train? I don't think you can.
