HRM math help please

Kate_UK

My HRM arrived this morning and I've just used it for my workout. I know I need to subtract the calories I would have burnt just sitting around doing nothing. But my question is how do I do this? Do I wear my HRM for a rest period and use this value? Or, do I use my BRM and work out my resting als from that?

Help please1

My blog post will tell you exactly how to calculate this!!

You can use your BMR or better yet your maintenance calories (anywhere in between would be fine) as you will not be in a coma if you did not exercise. Say your BMR is 1500 cals while your Maintenance is 1900 you would take that number and divide it by 24 to get cals/hour then divide by 60 to get cals per minute.

So if you HRM says you burned 300 calories in 30 minute you would enter somewhere between 260 (300-1900/24/60) and 269 (300- 1500/24/60). I would go with using maintenance calories, so you would enter 260 in the example above.
