When you get go for a run on the treadmill, do you have problems burning calories? Yesterday I went on the treadmill for 45 minutes. These were my stats: My average speed was 9.6 km/h, my distance was 6.85 km and I shed 520 calories. I was also on a bit on an incline I think it was 2.0. Now I'd say that's not a lot of calories for a 45 minute jog on the treadmill, but it's probably because of my size, I only weigh around 126 pounds. So it's a bit hardy for me to shed those calories. Thoughts?
