How many calories are burned during one hour bike spinning?

That totally depends on your weight, the terrain (are you riding uphill, flat street, or downhill) and how much effort you put into the cycle. In addition, what resistance (if any) are you going to...

In about an hour of spinning i burned arounf 570 calories.

about 360

It depends on your weight, your speed and the distance you walked but the average calorie burn for about a 130 pound person would be about 180 calories.

I would say walking for one hour at a medium pace would burn 200 calories.
