Weight weenies don't like triples but if you have knees over 40 those high non-hammerin' RPMs on a climb are good to have.

ha ha! thanks for the explanation. I already know I have bad knees and I'm only 25. When I was 16 and working at a grocery store I couldn't squat down very to load the lower shelves... My dad has had fake knees for years and I played a lot of catcher on my baseball teams so I attribute my sucky knees to my father and baseball.
