I have a question for everyone....When working out and doing cardio, what is your heart rate normally? Yesterday I noticed mine was in the 160-170's and Rick's was only at 130. I pointed it out to him, and he said that mine was way to high and it was bad. What's going on here, why is mine so high, and is it bad? I think we've all seen the charts on the cardio equipment that show the ideal heart rates for the fat burning zone and cardio zone, I am above the cardio zone, I'm a little worried now. An example of my typical workout is the elliptical for 30 mins, and this usually equals 250 calories burned and 2.30 miles....is this normal? Thanks in advance for any advice!
