Whatever you call it, it causes lots of issues: chronic neck and upper back pain, headaches, arm & hand tingling/numbness/achiness, creaky elbows and wrists, loss of range of motion in the shoulder, forward head posture and more.
When clients ask me, "Why do I feel like this? What can I do?," my answer is always the same, "You have to move! You have to counter the position you've been in." If you sit in the same position for more than 20 minutes you are depriving your muscular system of much needed and vital oxygen - you need to move!! So, get up, walk to the breakroom, or the filing cabinets, or down the hall to deliver something in person rather than via email - just move. If you can't get up or you have no where to go in the office, then try these simple yoga moves you can do at your desk.
