HRM

sonjasmith26

I bought a cheap ( like around 30 bucks) HRM from Walmart, its a sport line i do believe its a F7 but not to sure..... does anyone out here have one of these, b/c i just got done doing 78 mins of P90X shoulders & arms and Ab Ripper X and with both numbers combined together it says i burned over 900 calories..... i was just seeing if anyone has one of these and how accurate they are..... Also i need to add in that i am a heavy set person like in the 270's range, and again just seeing how accurate you think that is or not

I had one, and returned it 2 days later. i thought the numbers it was giving me seemed very high. I then bought a Polar for $65 (I believe), did the "same" 45 minutes of cardio and felt that it was MUCH more accurate.
