calories burnt doing bicycle crunches

How long does it take you to do them?

There's a website called FitClick that has a application that computes out that exercise and a list of others.

It shows that if you're weight is at 100 lbs and you did 150 crunches in 10 minute session (1 every 4 seconds), you'd burn off 28 calories over your normal metabolic rate.

Hi, thanks for the reply and help, it takes me 1 minute to perform 70 bicycle crunches, how many calories would this burn per minute, thanks,
Kelly.

Did you click on the webpage link that I provided? The answer from the charts are there to provide exactly those answers.

Hi, yes it said that i only bunt a few calories in 2 minutes, but i heard that doing 70 bicycle crunches in 1 minute burnt about 20 calories in 1 minute as it has a met value of 20, is this correct, thanks,

Unless you are only 3 feet tall, a 100 pound 27 year old need not be so focused on how many calories you are burning via exercise.
