Active Isolated Stretching (AIS) is one of the most popular methods of stretching utilized by today's athletes, chiropractors, physiotherapists, massage therapists, personal/athletic trainers, and professionals. AIS allows the body to repair itself and also to prepare for daily activity. The AIS technique involves holding each stretch for only two seconds.
This method of stretching is known to work with the body's natural physiological makeup to improve circulation and increase the elasticity of muscles, joints and fascia.
Aaron L. Mattes, creator of Active Isolated Stretching (AIS) has developed this method of proper athletic stretching over the past 35 years, working with thousands of patients, doctors, and health professionals.
