I'm going to run a 12k in Oct. I haven't worked out since my gallbladder surgery in Feb. I think I'll need a couple weeks of walking on the treadmill before I actually start running. I admit I am out of shape. I have a jiggly mommy belly, flabby arms and too much chunk in my trunk. I know I'm not far away from being in decent shape, I just don't know what steps to take to get there, especially now that I've committed to a 12k (the farthest I've ever run is 10k). In the past, I've never trained properly before a race but now that I'm 38 and flabby, I know I'll need to do it right. Does anyone have any suggestions?
