Active Isolated Stretching was created by world renound kinesiologist Aaron L. Mattes. AIS is currently being used by therapists, trainers, athletes at all levels and people who just plain want to feel better. This Video is intended to teach you how to effectively stretch yourself out and prepare your body for running. Whether you are a weekend warrior or Olympic athlete you need to properly warm your muscles up and prepare them for activity. In this Video you will see that you are using one muscle group doing the active movement to help stretch the opposite side muscle group while only holding the stretch for 1 ½ to 2 seconds. You will only want to use 3-4 ounces of assistance by either your opposite hand or a stretching rope. The video will take you from one stretch to another allowing you to work along with the model. If you have any more questions on the theory or uses of AIS please visit our web site at stretchingusa.com. Now please enjoy this video and get flexible!
