I did my 45 minutes as usual today on the treadmill and then out of curiosity I changed only the computer on the machine from female to male. Nothing else changed. On average for 15 minutes at 1.5 mph for a female, it is 36 calories burned. The same 15 minutes at the same speed for a male is 56 calories.
I think that the computers on these machines are based on an average weight unless the weight is actually asked for on the settings. If this is true then I am probably closer to the weight for an average man than for an average woman so I would be burning more than the machine says I am.
Do you think my theory stands up? LOL! At least it makes me feel better!
PS My curiosity also got in 15 more minutes on the treadmill too. So today I did 1 hour instead. Yay, me!
