What is AIS?

The Active Isolated Stretching (AIS) technique was developed by Aaron Mattes over the last 4 decades. His technique provides assisted stretching of major muscle groups, this means the practicioner provides gentle pressure to aid in the stretch. It is effective because it is dynamic, not static. Static stretching can trigger the body's natural protective stretch reflex, and fights the stretch. Dynamic stretches provide greater benefit because the body doesn't see the stretch as a traumatic event, so it will relax and allow the muscle to lengthen. This will improve overall elasticity and blood circulation.                                                                                                               
This stretching method is active, meaning the client is working one muscle group to allow it'sopposing muscle group to relax and lengthen. The muscles are stretched in a particular order, as they are layered upon each other within the body. This order allows a deeper release of the next muscle. Each muscle group is worked at multiple angles to obtain maximum flexibility through the all the fibers in the muscle. Sometimes the protocol for a particular body part may need to be done more than once for the fullest benefit, basically, baby steps. Clients come away from a session feeling "worked" yet flexible.
