I'm very new to running and quite out of shape. I get winded walking up a flight of stairs...I finished week 2 but I just didn't feel like my breathing or muscles were where I needed them to be. I was winded constantly and my leg muscles were tired and I could hardly move. I decided to start again at week 1 and am improving that way. I also use run keeper so I can track my distance and I know my pace is improving. My plan is to continue with week 1 until I feel like my breathing is under control and then progress more. Is that a good idea? I'm scared to try we 3 because if I'm not able to complete it (and I truly do not feel ready) I worry that I might just give up, which I do not want to do. Any advice?
