"The body will become better at what ever you do, or, don't do. You don't move, the body will make you better at not moving, by locking the tissues together. If you move, the body will allow you more movement." Ido Portal

That's my favorite quote from this video because it's been my experience. After more than 30 years with TOS, that's what happened to me. If your muscles are in spasms for years, over time, they don't move anymore. They get locked together, just like he says. I've been working on mobility for more than three years now but it's very hard to get back. That saying, "Move it, or lose it" is very true.
