The Active Isolated Stretching (AIS) method of muscle lengthening and fascial release is a type of Athletic Stretching Technique that provides effective, dynamic, facilitated stretching of major muscle groups, but more importantly, AIS provides functional and physiological restoration of superficial and deep fascial planes.

Active Isolated Stretching allows the body to repair itself and also to prepare for daily activity. The Active Isolated Stretching technique involves the method of holding each stretch for only two seconds. This method of stretching is also known to work with the body’s natural physiological makeup to improve circulation, decrease inflamation and increase the elasticity of muscle joints and fascia.

Active Isolated Stretching is beneficial for reducing pain, stiffness, chronic musculoskeletal conditions, and limited range of motion. It is an excellent system to integrate into a fitness program to continue to find joy in movement.
