J.J., you are right. My cardiologist actually gave me the numbers of what he wants my heart rate at while exercising. That is exactly why I don't walk and do all my exercising in my own home on all my own equipment. I take my pulse rate at different intervals to be sure I am where he wants me to be. I know if I were to walk outside I would be talking to all the neighbors and never get that heart pumping and exercising as it should. On the other hand, the girls at work want to start walking at lunchtime. That would be fine so long as I don't stop my regular exercising at home as well.
