I have a Polar hrm. I paid $90 for it and assume it is a pretty good one. It seems to match up well when I take my pulse the old fashioned way. Here is what I have noticed.
For example, I put on my hrm today because I was about to work out on my elliptical. I worked out....had a nice warm-up...got my hr up a little bit....cooled down. When I got off, I sat on couch for my dear husband to give me a little shoulder rub...got relaxed....went right down to my resting hr.
Then....I was still wearing it and noticed as I move from sitting to standing or vice versa...it shoots up (or down) about 20 points. Is this normal or is my monitor not working? It seemed to do just fine during exercise.
I want my gadgets to help me...not confuse me, you know? I am the world's best buyer of fitness videos,equipment..but am still trying to lose the same 20 pounds.
Would appreciate insight from anyone who uses a hrm.
