The vast majority of issues arise from lack of movement and secondarily some kind of injury. It is important to move regularly, stretching and strengthening through activities like walking/hiking, yoga, pilates, swimming, and dance. Even a small increase in movement throughout the day will make a difference. Move in as many different ways as possible, particularly ones that explore and utilize your new range of mobility. If you work a sedentary job or physically demanding one, take lots of breaks, explore dissimilar movements and stretch in the opposite position when not working.
