Calories Burned is not matching

vintageprop

Hello I was wondering if someone could shed some light on this as I'm entirely confused.

I used a stationary bike for 40 mins and the machine said I burned 75 calories. I input my weight at the beginning which is 117.

Online when I input 40 mins of vigorous stationary biking with my weight, it says I burned about 400 calories. That just doesn't feel right.

How do I know which one is more correct? Should I just buy a heart monitor calorie counter watch or something?

if you just sat and stared hard at the bike for 40 minutes you could burn 75 calories

400 is more likely if you broke a sweat

More likely, it's somewhere in the middle. The only real way to know is to get a HRM that tracks your calories burned.

A heart rate monitor is a good investment. I use a Polar F6 when I'm on my elliptical the difference is always higher on the machine, so I wish it were the right one. :happy:
I burn an average of 100 calories per 10 minutes of sweaty, vigorous exercise. Sounds the 400 is a better estimate than 75 but then again even 400 could be high for you (you're only 117 lbs, heavy people usually burn more calories doing the same thing).

LOL! Nice... I agree with Dave that 400 is closer to being accurate.

yeah, you're right, 75 does sound a bit ridiculous seeing as how I did sweat a lot. Thanks guys
