Just started running today for the first time in about 15 years. Started at a mile and I did it in 9 mins and 30 secs and feel like Im gonna die. lol. Im 34 weight about 210 and Im 6-1. Usually lift around 4-5 times a week and Im a Letter carrier so I walk (At a brisk pace for about 3-4 miles a day 6 days a week). Im just looking to shred a few lbs and get into better shape. I can walk around the world if I had to but when it comes to jogging or running ah not to good. Any suggestions? Should I keep with the mile for about a week then jump up to 1 1/4 next week and keep jumping up every week? Thanks
