I run two miles a day twice a week and walk the two miles three days a week. I used to run the two miles 5 days a week, but I was found to have some kind of anemia, so the doctor limited my running. I never liked running until I was in the Marines and there you learn to like it because you get to do plenty of it. Walking is OK, but it has much to be desired. My wife walks and she also carries dumbbells (not me). I try to get my heart-rate over 120, but stay under 155. I sometimes where a heart rate monitor to measure my pulse.
Just as a clarification, I
do not run like a jogger. I run like a 67 year-old man. Faster than walking, but slower than my 41 year-old neighbor does when he runs. When we leave at the same time and we run the same course, he is usually finished ahead of me by 2-3 minutes.
All of this running has caused me to have a slow resting heart beat, which every doctor has told me is good, so long as it is due to being a runner. My doctor just wants it to stay above 50.
I also have PMR, which is painful, but I make the sacrifice. The doctor says if I can stand the pain it's OK because I am not causing any additional damage by running, except more pain. But like they say, "No Pain, No Gain." I take two Alieve and two Tylenol (4 pills) together, if the pain gets too bad, especially if I run before bedtime. Prednisone works the best, but it has too any possible side effects.
