You know how stiff your body feels when you finally get out of a chair after hours of crunching numbers or going through email? Fortunately, it only takes a few minutes to stretch. Some stretches can even be done while sitting in a chair or standing in front of your desk. If you happen to have a yoga mat, take it with you on your break or your lunch hour to a private, peaceful area and do some stretches. You’ll feel rejuvenated, flexible, centered, and happier.
