My record is an hour walking on an incline, burned about 500 calories. Did that a couple of times. When I was running on it I burned 250 to 300 calories but I don't remember the exact times, it was under a half hour though. My biggest gym accomplishments were cardio related. I went to an chain gym and there only one bench that was in use 99 percent of the time so I got to bench only the bar once for a couple of reps. Most of my strength training consisted of dumbells, machines and fix barbell bars, had so much fun and it was fit to boot!
