I really want to do intervals at the gym on the treadmill but I feel really self-concious. I used to do it at our old apt gym because I was by myself. I know I shouldnt feel like that because we are all there for the same reason but I just feel really wierd. Anyone else feel like this when you first started? I just feel self-concious about everything ( classes, running, weights) but I feel even more like that towards running.
