At work I did a standard Max O2 test on a stationary bike. In the hours after I didnt feel so good. Is this normal? If not, is it likely that I have a low tolerance for exercise? Or is it just that I am not very used to it? (Would it be the Biking or the intense exercise?.
Right now, I do not have a high fitness level, but my health is good. In the past, I feel I always have had problems with exercise, even when I was in good shape.
