I can't seem to get on with the ones in our gym at all. My knees get sore very quickly, I can't get into any rhythm. I have to stop after less than 5 minutes.
(I usually do 10 minutes rowing and 20 minutes running as well as some cycling, so I don't think it can be because I'm ridiculously unfit.)
Might it be because I'm 5'1? Anyone else had this issue.
