Active Isolated Stretching (AIS) is a dynamic stretching technique that restores mobility, releases tension, and helps your body move the way it's meant to — without the drawbacks of old-school static stretching.

For decades, the standard advice was to hold a stretch for 60 seconds. But prolonged static stretching actually restricts blood flow, causing tissue irritation and increasing injury risk. AIS takes a different approach: short, repeated stretches that work with the body's natural response instead of against it.
