“An active walk gets me to 120-130 and the slowest jogging possible gets me to 150-160.”
That’s strange.
Have you tried walking faster than your “active walk”?
Have you tried “running” slower thank your “slowest jogging possible”?
“I figured my Z2 is around 135-150 but I can’t get my HR to stay there!”
How have you determined this?
Was it just based on “220 – your age” formula or determined through some trial walks/runs?
I have a perception that for some people (e.g. for me) an error can be up to 20 bpm when using this formula.
For example, for how many hours:minutes can you run with your “slowest jogging possible” speed?
