For the unbelievers

My calorie burn

For the folks out there that think a spin class is just hype – you know who you are – check this out! This is the stats from my heart rate monitor which I wore during class today. That’s 841 calories in just under an hour (of which, the last 10 minutes is stretching and stuff). That’s workin’. (The 30% is the percentage of calories that I burned from fat. Once you exceed a heart rate of about 165bpm, you’re burning the majority of your calories from carbohydrates. But the overall effect of frequent exercise at this intensity is that you’ll raise your metabolism, which means you’ll burn more calories while doing nothing!)

Still, I’ll admit that you can burn more Calories by doing the ordinary, everyday cycling, especially if you go riding with Bender.

Anyway, it got me thinking. 841 Calories converts to almost 1 kilowatt-hour. Presuming everyone in the class is working at approximately the same rate (which they weren’t!), and that there was about 30 people in the class, we collectively generated about 25 kilowatt-hours of energy. Why hasn’t someone come up with a way of harnessing that energy, and pumping it back into the power grid? Given the number of gyms in New York, and the number of spin classes they must run per week, and combine that with the regular cardio rooms that all these gyms have… that’s a lot of energy being wasted!

    Hey Guys,<br><br>Yes, I’m an avid reader of the blog and drop by often to catch up on the wacky adventures in the US of A :)<br><br>On the metabolism statement (how could I resist, mr personal trainer and all) there are a few more ways that you can raise it and burn your excess energy storage (or fat) more effectively. You can be male (sorry Kristy, but the male physiology naturally has a better metabolism), you can move to a cold climate (clearly you guys did just to improve your metabolism), eat more spicy foods (see you at enchiladas), exercise more (and you’re doing an awesome job) and move more.<br><br>On an interesting side note too… doing a 1/2 hour weights session gives the same metabolic and physiological benefit as a cardio session, obviously without the cardio benefit, and with less time, so keep that in mind if you’re in a rush, hit the weights and reap the benefits!!! And remember be safe with the weights, I don’t want to hear about any injuries :)<br><br>That is all :)
