Well I like to be more accurate than gauging my aerobic activity level by how much I sweat. Aerobic activity is characterised by achieving a heartrate between 60-80% of your recommended maximum heart rate (which is usually 220 minus your age) for at least 15-20 minutes. Don't you think that gauging your aerobic activity level by how much you sweat is quite inaccurate because of ambient temperature? If you are in a nice cool gym at 70 degrees running on a treadmill you are going to sweat less than if you are running outdoors in 95 degree heat? But you still are burning about the same amount of calories. How about running in the dead of winter versus running in the summer. I think you can understand how inaccurate using sweat as a measure of aerobic activity is now.

True the only way to really gauge body fat percentage is by water displacement or skin calipers but for the most part I can tell if someone is skinny, average, or obese once they put their height and weight down. It is usually obvious like if someone is 6 feet 160 pounds that would be skinny versus someone 6 feet 185 who would be average and someone 6 feet 210 who would be slightly overweight and then someone 6 feet 235 who is obese.
