SP calorie burn or a heart rate monitor?
When I first started out on this journey I used SP's fitness tracker and took what they said I burned in calories as being correct. However, I just got a HRM for Christmas and I've been using it to calculate my calories burned (darn thing doesn't actually TELL me, I have to figure it out on my own...ugh).
Well, this morning I decided to compare the two. SP said that 20 minutes of low impact cardio burned 230 calories. Where as with my HRM and my average heart rate...I burned 120 calories.
Say what? That's a 110 calorie difference!
Now, I lost a lot of weight when just doing the SP thing...so how wrong CAN it be if I was losing weight on it? Which should I trust more? SP or my own heart rate? Do you guys use HRMs? Are they a waste of time? I just don't know anymore. Ugh.
I'm starting back up on this journey and I want to be as accurate as possible with this. So does anyone have any experience with using a HRM? Mine's a Mio Motion HRM.
