As a former personal trainer and survivor of the cubical farm, I understand and want to help you feel better.
The benefits of stretching are increased circulation, reduced stress (that is a biggie), increased flexibility and range of motion, reduction of back pain, improved posture and better mental focus. These are some of the benefits. The one I like best is it just makes me feel better.
Take a look at the stretching videos and try them. You will be amazed at what five minutes of stretching can do for you!
