Is it just me or is my exercise bike busted??

Hey, I'm 13...5'6 107 lbs

i tried working out on the exercise bike my parents bought recently...the problem is that no matter how fast i go i burn only about 12 calories in 25 minutes!

i used to workout on the treadmill before and burned 150 calories in the same time...

i think there's something wrong with the bike...coz i go pretty fast and it takes forever just to burn 1 calorie...strange

At what speed do u usually workout on ur bike and how many calories do u burn??

i seriously think something is wrong with the bike...or is it just me going too slow?

dang...seriously busted. check under activities>>conditioning exercise and select stationary biking, general for the REAL amount of calories you're burning (according to your weight).

Perhaps you're not seeeing the calories but something else? (speed, resistance, distance, etc) that used to happen to me with another bike...

One of the things I realized with these bikes is that you really have to do one of two things to burn the calories... 1. turn the resistance up a lot, or 2. pedal pretty fast.  Still, I think 12 wayyy off.  I usually burn like 37 or so in 7-8 minutes but that's not going very fast.  I took a few spinning classes and a great thing to do is either "mountain climb" which is turning up the resistance, peddling, then up again.. until you get to as hard as you can go, and then go back down.  Another thing was "sprinting".. put the resistance at about your own personal level 5 (about half as hard as you can go) and then do 10-30 second intervals with slowing peddling in-between.  These should help burn more calories than just straight peddling.  But I would definitely get the real calorie count.  I would guess its more around 200 or something.

A lot of exercise bikes display a ton of information. It's possible you're looking at calories burned PER MINUTE rather than total calories burned. Simply change the selection dial (or whatever your bike has) and you should get the total calories burned per session.

When I use a recumbent stationary bike on the lowest difficulty, I often burn 200 calories in 30 minutes. So if a slug like me can burn almost 7 calories a minute, your more atheletic frame could burn 12.
