Active Isolated Stretching (AIS) is a technique that helps people maximize the effectiveness of stretching without causing the sort of discomfort that keeps a lot of us away from it.

AIS is a specific stretching program developed by Aaron Mattes over 30 years ago. Mattes is a registered Kinesiotherapist and Licensed Massage Therapist who has dedicated his practice to helping both professional and amateur athletes become more agile and less injured. His technique uses four basic principles:

Isolate the muscle to be stretched.
Repeat the stretch eight to 10 times.
Hold each stretch for no more than two seconds.
Exhale on the stretch; inhale on the release.

After a long hike, walk, or run, what are the problems that pop up and keep you from going out again? For most of us, it's the same patterns: sore muscles, old injuries, and new injuries. These things make it hard to go out and have fun while training.

If you could take a pill that would keep your muscles from being as sore, improve your ability to recover, and decrease the likeliness of injury?do you know what they'd call it? AIS. Whether you're an exercise enthusiast or a competitive athlete, Active Isolated Stretching can help your training and recovery become more efficient and more fun.
