| low heart rate My usual heart rate for running 10k would be between 158 - 168.
Lately I ran a very good time at 154 so I thought this would mean I
could go faster at the higher heart rate. But this is not happening.
I just cannot get my heart rate into that zone anymore. Today I was
doing some repitions and I felt as though my chest would burst and
even my arms were going sort of numb yet my HR stayed stubbornly at
145!! My legs were aching too. This has been happening most of this
year so its not an isolated incident.
Any suggestions?
Thanks Jaja |
