i didn't do anything i shouldn't have. just got on it(after 30 min on treadmill), worked for 5 mins, and got off. no accidents. according do Elizabeth, my dr, this is quite a common injury from using the stairmasters. seems the pressure causes the knee cap to chip or crack. I won't be using either machine again. i'll stick tot he coross trainer which is zero joint impact.
