HOW IT WORKS
1. SETUP & CYCLE MODE
Put the AirBands on your upper arms or legs and start our patented Cycle Mode, where gentle, rhythmic pressure safely increases blood volume in the limb without heavy effort.
2. FULL-BODY RESPONSE
That change in blood flow sends a signal to your entire body that stimulates hormones and growth factors tied to repair, circulation, and muscle development.
3. MULTIPLE BENEFITS
This response lets you rebuild tissue, strengthen muscle, and support cardiovascular and metabolic health with minimal joint stress and far less mechanical load.
4. KAATSU FOR ALL
KAATSU uses patented AirBands and algorithms that optimize blood flow without cutting off arterial circulation, making it safer and usable across ages, conditions, and goals.
