I've been going to the rec center 2 - 3 times a week since the beginning of the year. I go upstairs to the walking track. I walk a lap, run a lap, walk a lap. Then I use the hydraulic weight machines, running one and walking one lap in between each machines. I do 15 reps on each machine. The running track takes 16 laps for a mile. With eight machines and two laps between machines, I always get to a mile and a half, and most of the time to 2 miles. I want to run longer, do more resistance on the machines, and add more laps, but it feels good to be making progress. Weight Update: 3/23/11 206 pounds
