Does anyone know of a way to calculate this somewhat accurately? I really want a HRM with a calorie counter, but don't have the spare $$ for one right now. I do have a HRM watch, but that's all it does. I feel like I am burning more than what it says when I enter in my activity on Fitday.
For example: I walk/jog for 3.5 miles several times a week for 45-50 minutes. Fitday says that burns 260 calories. But I check my heart rate every few minutes and it is always around 160-170. I feel that since my heart rate is staying fairly high, I should be burning more calories.
Any thoughts? Suggestions? Thanks!!!
