Active Isolated Stretching: Is assisted stretching performed on a massage table.
AIS is a specific stretching program developed by Aaron Mattes over 30 years ago. Muscles are isolated and the assisted stretch is held for 2 seconds and repeated 8-10 times. AIS maximizes the effectiveness of stretching without causing the sort of discomfort that keeps a lot of us away from doing it. It is a wonderful diagnostic tool to pin point injures or imbalances so that health can be restored.
