Why do we hate to STRETCH?

Have you ever gone to a fitness class and half of the class leaves before they STRETCH at the end?  Why do we put so much emphasis on pounding our bodies, trying to get in shape, without STRETCHING?

STRETCHING is the most important aspect of your workout, if you are stretching properly.  I was introduced to a new technique called ACTIVE-ISOLATED STRETCHING (AIS)  several years ago which has changed my life.  Unlike traditional stretching, holding the stretch for 10-15 seconds, AIS holds the stretch for 2 seconds, repeating the stretch for 8-10 repetitions.  Research is finding that after 2 seconds the muscle you are trying to stretch actually goes into a contraction.  So why are we trying to stretch a contracted muscle?

Research is also finding that holding the stretch longer than 2 seconds constricts blood flow. The AIS technique is like a pump, pumping fresh blood and oxygen into the muscle. So why do we continue to static stretch which constricts blood flow?  

Why do we hate to STRETCH?  Could it be that traditional static stretching doesn't work?  If you are trying to get in shape and want to feel good doing it, I highly recommend ACTIVE-ISOLATED STRETCHING with your next work-out.
