Recognize that the way you exercise has significant influence over your function and fitness, and your dysfunction and pain. Training like what you see in the mainstream gym culture likely produces the same results- decrepit posture, lower back pain, a knee brace, etc. Movement that replicates the mechanics of the way the human body moves day to day, has carry over to life outside of the gym. Ergo, pain free recreational activities and sports, no joint stiffness or muscle tightness, and an overall freedom to move!
