I have never trained on a Makiwara. I do not have one at either of our locations. I have been told the drilling with this tool does make your fists tougher and gives you instant feedback on proper alignment or lack thereof. It is on my to do list- for our Orlando Road location. Enjoy.
On a side note, I am back now posting several times per week. The end of summer was extremely busy with summer camps and my two little ones starting school. We had a great summer and this year is shaping up to be quite dynamic.
