I'm a 29 year old woman. Not in the greatest shape sinse I had my baby and hysterectomy. At rest my heart rate is between 85-100. I know when you excersise you want to get your heart rate up, but how much? I want to start doing some running again and more arobics. I have never pushed myself too hard before, so my heart rate never got that high. But I feel ready to kick up my routien a notch or two. What happens when you get your heart rate up too high?
thanks everybody
