Yeah, that's what I said ~ "Do you feel a little "uptight," or stiff and crickety these days?  We've all been there.  Research shows that exercise is the best medicine for your joint stiffness.  According to Prevention magazine, "…exercise is the best thing for tender joints.  It builds muscle, stabilizes joints, promotes flexibility, and keeps your weight down."  For every extra pound of weight you carry, it exerts roughly 4 pounds on each knee!
