Active Isolated Stretching
Active Isolated Stretching (AIS) is a widely used method of stretching used by doctors, therapists, and athletes to increase the body's potential to heal and increase performance.
Aaron L. Mattes is the creator of AIS, and has spent the last 33 years developing the Active Isolated Stretching Method (AIS).
AIS is the most gentle, least invasive, yet most effective method of stretching to increase flexibility and improve posture and performance.
