While doing Power 90 today, I glanced at my watch to check my heart rate and it was over my max. Not a lot, it was 176 and my max is 174. I stopped what I was doing until it came down a bit but is there a way for me to program this to beep or something when I go over? Also, is there a more accurate max heart rate predictor than 220-age?
