Since I got up late this morning and didn't have time to workout I decided to do it this afternoon. I worked out 30 minutes on the treadmill and it said I burned 170 calories, so I thought that was great. Well when I got on here and logged in treadmill 30 minutes for cardio it came up has burned 90 calories. I don't get it which one is right the treadmill or spark?
