Off to go for my walk, thankfully the sun is out this morning. When the sun is out all is well in my world

how much walking is going to be cardio and not just movement is going to depend on one’s shape .
walking for most fit people isn’t going to improve cardio much as like any muscle the heart only responds to what it doesn’t do efficiently yet or what it is NOT used to .
like i said my blood pressure was high , my sugar high and my cholesterol high even after decades of bike , walking and elliptical.
the measurable differences didn’t happen until i went outside my efficiency zone .
what was interesting was after my wife and i were hospitalized for two weeks with delta covid and on oxygen in the hospital we required no rehab or even oxygen after we were released .
within a week we were back to our routine doing our photography and walking hills and miles .
however while i could do all the things in life i typically could , i couldn’t run .
my heart rate would shoot up in minutes and i felt winded ….
i was concerned so i saw the pulmonologist i was assigned when i was released from LIJ hopital .
they saw nothing so they sent me to the northwell cardiology center .
they did an echo stress .
First thing they said to me was are you a runner? i said yes i was running 3 miles every other day up to covid .
they said they can tell by the pumping and flow rate of my heart which was high for my age .
stress tests use a standardized scoring system .
it runs from 1 to 12 ….8-10 is normal .
i breezed thru ten and they had me try 11… 11 was no problem .
they didn’t bother with 12 since they already saw i was way above normal..
they said that the intense cardio grows everything so much that i lost that excess capacity….
they said stick with the running and it will come back .
sure enough it took 9 months to grow everything back to where it was prior to covid .
today i have broken all my previous records.
so don’t confuse what is movement, what is exercise and what is cardio growth.
they are all different levels of heart rate where you work at
anyone seeing heart rates in the cardio workout range walking better see a good cardiologist
