An instructor asked “One of my students asked me why he burns more calories when he rides outdoors than in Spin class”. This is an important question, and may not be the answer you expected! In fact, this might have each and every one of you paying a little closer attention to your indoor cycling workout… ICA member Nancy sent me this question:
One of my students asked me why he burns more calories when he rides outdoors than he does in Spin class.
This is an excellent question because I think a lot of people have probably wondered something similar!
However, there really isn’t one answer because there are so many variables and so many potential reasons that this is happening. So many that I don’t believe it’s possible to compare energy expenditure indoors to outdoors.
The first question I would have is what is he using to measure caloric expenditure, a heart rate monitor (HRM)? They are notoriously inaccurate.
