| I have bad knees from a skydiving accident that I continue to abuse in martial arts. The only time they really bother me though is when I am hiking a trail that requires jumping down or running on a treadmill. The eliptical has been a lifesaver, but I still prefer outdoor running. I dont deny that I will pay for the abuse in later years though. 
 An eliptical, swimming and trunk/ upper body workouts using one of those pilates balls are a great workout combination.
