She sent me this formula:
If you are 57, take 220-57=163 (max HR)
Low intensity cardio (start with ) 163x.65=106
Mid intensity (in a few weeks for 30 minutes) 163x.75=122
High intensity 163x.85=138
Never, never go over 163 for you. You are stressing your heart way too much and may precipitate a MI.
Sooooo, I'm rethinking my whole approach at the gym. Here I've been thinking that the more the better. This may be true in terms of length of cardio workout, but it definitely is not true in terms of intensity. So, in direct opposition to Emeril's standard advice, I'm going to
take it down a notch..or maybe a bunch of notches. I was so scared, that today I didn't go to the gym. Instead I went to the beach and swam around for about a half hour.
I'm going to try to go to the gym tomorrow and really pay attention to my heart rate. Like Goldilocks, Not too fast, not too slow, I'm going to be shooting for Just Right. And maybe start looking around at some of those weight resistance machines, whatever they're called.
