I've developed a new theory about running -
I think it's important to monitor your heart rate while running.
I think you should have a running window. Not too fast and not
There is a "calculated maximum heart rate". It's supposedly the
maximum you should allow your heart to beat. It's (220 - age).
There are some problems with this. I think for people in their
twenties it give too high of a number and if you are over 60 it
gives too low of a number. At 74 my number is 146. I feel this
is too low. I find I work out around 155. This may be because
I've been running for 25+ years and am in pretty good shape. So
my running window is 150 to 165. It takes me about a half mile
or more to get up to 150 I then try to keep my heart rate below
165. Sometimes it goes higher if I sprint or run up hill. No big
problem but I do try to stay in the window.
I also think you should run at least 35 minutes and not much
over 40 minutes. I think this gives you a pretty good cardio
workout with few injuries or burn out.
