I'm not ticking right

[johnbench110]

Dear Mr. Kurz,

to improve aerobic fitness I run twice a week for around 40 minutes on the day after my strength training day.

According to column #19 my heart-rate value (180-age+5) should be 155.

I have been running for a good 7 years but bought a puls watch only 2 months ago.

The puls watch is supposed to be as accurat as a Doctors ECG but I' m having a hard time to maintain

a constant puls. I tried breathing in and out for 2 steps each and for 4 steps but my puls goes either to

high or to low.

Now I'm wondering if it is possible to run for 30 to 40 minutes w./ a certain puls and how to do that?

Try this: Run two or three days after your strength workout, or even take a week or two off your lifting weights and then do a few running workouts. See what happens.
