Active Isolated Stretching (AIS) is one of the methods of stretching most used by today’s athletes, massage therapists, personal/athletic trainers, and professionals. It allows the body to repair itself and also to prepare for daily activity.

This method of stretching is also known to improve circulation and increase the elasticity of muscle joints and fascia. It provides functional and physiological restoration of superficial and deep fascia planes.

There are two primary principles that provide the basis for how AIS works. The first one involves your nervous system and in the process, re-educates the muscles how to function properly and how to utilize and maintain full range of motion. The second principle is to hold the stretch for 2 seconds - relax - repeat.

This method was developed by Aaron Mattes over 35 years of close collaboration with patients, doctors and health professionals.

AIS works best for people who want to learn to be more flexible by learning how to do stretches as part of their daily routine. Athletes benefit largely from this method of self-improvement.
