Back in the bad old days I used to have to choose between swinging swords and working. Every time I picked up a sword, my wrists would swell up and my hands would be useless. It was hell.
Then I met a kung-fu instructor, Num, who in 20 agonising minutes fixed my wrists. And in the next 20 minutes, showed me how to keep them fixed.
Since then I have taught this system to hundreds of my students, and successfully treated many of them for tendonitis problems that were getting in the way of their training. The biggest cause of the problem is computer use. It promotes poor posture, and it forces the small muscles that control your hands to work at low intensity for hours at a time. No wonder things swell up and stop working.
I have had videos of forearm exercises and massage techniques up online for years now, but most people find a properly structured course easier to follow so I have shot and edited one, and uploaded it to the Swordschool Online teachable platform, here.
This course is entirely free; I view this kind of essential maintenance training as part of your birthright as a human being. Please share this with whoever you think might benefit from it.
