Somehow over the weekend, I injured my upper arm/elbow area.  It could have been the golf, P90X2 workouts or football tossing on this gorgeous weekend.  Whatever the case I will be taking a week off from the P90X2 to rest the arm.   I will not just be laying around though, instead of using my arms, I will use this week to concentrate on legs and ab work.   Plenty of walking, swimming, and ab exercises while my arm gets back to 100%.
