Originally conceived by Aaron L. Mattes as a means of sports therapy more than 35 years ago, Active Isolated Stretching (A.I.S.) has long since established itself as a pragmatic, easy to understand and to apply means of relieving pain, imbalance in the muscles and postural problems.
The 4 Basic Principles:
- Isolate the muscle to be stretched.
- Keep the muscle 30% active during the move.
- Hold each stretch for no more than two seconds.
- Exhale on the stretch; inhale on the release.
Repeat the Active Stretch 5 to 10 Times
Active Isolated Stretching is not just an encyclopedia of useful stretches.
Most importantly it is a new way to approach stretching and muscle-activation. It is a way to reconsider what is possible and achievable through the use of range of motion.
