Thanks. I for one found the clip helpful. Naturally, I was paying most attention to where I think I'm making my mistakes- for me- the legs. I'm having trouble learning this pushing. We have a similar safety set up on a wall in our dojo. We have an internal martial arts instructor that comes in and teaches us, mostly black belts from a more karate hard style. He says we are making progress but I for one feel that on these pushing exercises and push hands exercises, that I'm getting no where.
The older I get, the better I was!
