I have always enjoyed hitting the gym. Since my high school days the majority of my work outs have consisted of lifting, lifting, and more lifting. I would often skip stretching and anything to do with core and/or cardio. That is, until about five years ago, when I was swinging a golf club and threw my back out. For about two weeks, I was on the proverbial shelf. After a tip from a friend I set an appointment with a physical therapist.
