It’s not uncommon to spend eight or more hours seated daily. This places undue stress on some muscles while others weaken from disuse. Add improper posture to long periods seated, and you have a recipe for chronic muscle pain and stiff, achy joints. If you’re dealing with chronic pain stemming from poor body mechanics, it’s not too late to correct the problem. A regular tai chi practice can help realign the body, balance muscle use and improve muscle and joint health.
