Has anyone tried Active Isolation Stretching (AIS)

I’m thinking about starting this stretching program and wondered if anybody had tried it
.

I plead ignorance. What is it and what is the website?

It is great. I have been doing it with my massage therapist for about 3 years. I am not as diligent as I should be, but it definitely feels great. I think it does much more for ROM than regular stretching and is less painful. Definitely buy the book.

What is it? and can it help with tightness. If there is a book what is the name of it? I’m looking for a good program to start this off and carry over to next season.

I’ve used it on and off. Not nearly as diligently a I should. It seems to work better, for me anyway, with certain muscle groups than others. Doesn’t seem to do anything for my calves, but helps the hamstrings alot.

All in all I mix it in with other stretching and rolling etc.
