HI all

I'm a HRM Newbie. :bigsmile: I was just curious about the HRM w/strap (Sportline Duo 1010) and those of you that have one, any one. I went running yesterday and wore mine for the first time running, second time working out. The first was in the studio doing cardio. I made sure that I wrote my numbers down as I had already been doing Wii Boxing and Wii Tennis. This HRM showed that I burned 430 calories in a 20 min. run. In fact, I backed my pace down to keep my HR down.

Does this sound like an accurate amount? Everyone is different I know. I am not new to exercising, just the HRM! lol

Thanks!

(Sorry for typos I am on my sons computer and it's tiiiiny! lol)
