Jason C. Brown is a pretty smart coach by the way, and this product may very well be worth it.

This is a high form of exercise. It is wave dynamics which means you will be able to do contraction and expansion simultaneously unlike point line motion.

On the martial side, wave motion amplifies the aspects of speed (distance over time)and power (speed times mass).

The local university doesn't offer judo.

where are you?

Shijiazhuang, Hebei.

I see.

Some old teachers of mine have a school at YanTai. Maybe I can ask some friends if there is a college in between there with Judo club.

if you could afford the train, i know that Beijing, TianJin and Taiyuan are probably only 3-4 hours away.

Beijing University of Physical education is where a lot of the higher level San Da fighter and Judo competitors train, but I never saw their Judo practice myself, so I could not comment.
