I just wanted to show you that the cardio machines we use are not accurate. I never rely on the cardio machines to tell me my caloric burn or heart rate. This picture is from my Saturday morning workout. My polar FT4 watch told me I burned 394 calories and this treadmill told me I burned 542 calories ( a 148 calorie difference) without even asking my height, weight, heart rate zone, if I was male or female etc.... All of those factors play an impact on calculating accurate numbers.
This treadmill had no idea if I was a track athlete which made this run a breeze to complete with minimal effort ( low heart rate ) or if I have never worked out a day in my life and It was a major struggle to complete it ( high heart rate ). ALSO, the treadmill had no idea when I rested my feet to the sides to take some drinks and catch my breath a little…..hmmmmmmm!!!
I love my polar watch. It knows everything about me and that makes it close to accurate. It actually has a band around my chest that is catching the beats from my heart. It knows when I am working hard and when we are resting. It knows my height, weight and knows I am a girl. I would recommend a heart rate monitor watch to anyone. Particularly this polar FT4. It is not expensive and very easy to use. I got mine from Amazon.
