1st question-Hey so I'm 18 and about 6'2 and 155lbs and I'd say I'm in decent shape. But I really want to be able to run 5k races and other stuff. I was wondering if anyone has tips for getting endurance up or how to run long distances because I can only go for maybe 1/4 of a mile and I feel like I can't run anymore. 2nd Question- I really want a pack of abs. I'm willing to work hard for it and I usually workout like 2-3 times a week but it doesn't seem to be doing me any good. Any suggestions as far as abs or just bulking up in general and getting muscular? By the way there isn't any motive behind this except for the fact that I'm very self conscious and would like to be in better shape. I come from a long line of diabetics and people with heart disease and it's better to start now and get in shape.
