I have noticed that many people including myself have hard time moving slowly when we exercise. I so often have to remind my clients to slow their movement down many times.  I must admit that I had very very hard time to do that.  It took me a long time to learn that.  

I used to hate walking because it was too slow and boring.  I used to prefer running to walking. In the last few years I've learned the benefits of moving more slowly.  When we move fast, we access movement patterns that have been used many times, called habitual movement patterns.  We use the sub-conscious part of our brain, which responds very fast.  This is useful when we have to move quickly during emergency situations. However, when we're learning new movement patterns, we have to rely on different parts of our brain, conscious part of the brain, which acts much more slowly.  In order to allow us to access this part of the brain, we need to move much much more slowly.  If we move slowly, we won't bypass our sub-conscious part of the brain and inhibit habitual patterns.  This is one of the key principles in my movement re-education.  When someone keeps hurting because of their habitual movement patterns, they need to learn how to move differently.  If they try to move fast when learning to move in a different way, their habitual movement patterns keep interfering.  This is why it's a common practice for Tai Chi and Feldenkrais Method to move very slowly so they can pay attention to how they are moving and they can adjust their movements continuously.  I must tell you that this practice has completely changed the way I move and the way I work with my clients.  I've learned so much about how I move and definitely improved my movement quality.  By the way, the same mechanism applies to thinking, feeling, and sensing.  How we emotionally or intellectually react works much like our movements.  To break your habits, you'll need to SLOW DOWN.
