318/365 Online Calorie Counting Calculator

Friends and Fitness Enthusiasts,

My coworker Libby and our intern Maddy have the same Polar FT7 watch/heart rate monitor/calorie counter which they were persuading me to buy. The only difference between theirs and my Polar heart rate monitor is that theirs has a built in calorie counter. I thought to myself, certainly it's just using some formula based on heart rate and age since it can't sense the heat you emit, the steps you take, and how fast you move like a bodybugg does. So I used my googling powers and found this website. By typing in your gender, age, weight, avg heart rate during exercise, and the duration of your exercise, the site figures out how many calories you burned. We tested this against what their watches said when they exercised and there was a margin of error of about 50 which is a lot I know but it's helpful when you're doing a group ex class, running outside, spinning, etc.

In health,

Lauren
