Could somebody give me an idea of how to figure out the number of calories I'm burning on a stationary bike?
The bike I'm using is a cheap Pro Fitness magnetic bike from Argos (http://www.argos.co.uk/static/Product/partNumber/9237386.htm), and it comes with a digital readout of speed, distance, pulse, calories, etc. but the calories stay the same no matter what setting I ride on.
In other words, if I do 45 minutes at 30 kph on setting 1 (extremely easy), the calorie readout will be the same as if I do 45 minutes at 30 kph on setting 8 (around 200!). Obviously this cannot be true.
I've been using this site (http://prod.bicycling.com/training-nutrition/training-fitness/cycling-calories-burned-calculator) to get an estimation of my calories, and the calculator says I will burn about 750 calories for a 45 minute ride at 30kph, but the calculator is for bicycles and not stationary bikes.
Are there any guidelines or info for stationary bikes only?
