Now that you have found your "trouble area," you need to work it every day until it is no longer your trouble area. If you don't yet know how to work through the muscles in that area, click here to download the SMR Introduction. You will get your best results by applying gently increasing levels of pressure to the tightest knots in your muscles for at least 30 seconds. Autogenic inhibition takes at least 20 seconds, but can take much longer. It is the physiological response that causes your muscle knots to relax.
It takes your muscles at least 3 weeks to remodel the number of sarcomeres (the smallest functional units within the muscles) so that the tight and shortened muscles stay lengthened and allow more functional movement, so STICK WITH IT!
