Just got myself a fitbit
I can't seem to get in the "cardio zone"
I am 50, 6ft, bmi 24. Resting heart rate around 60, when I run it goes up to 120
but it does not really peak over 130
So fitbit tells me I'm not doing cardio, but am in fatburning zone at best, even though I FEEL as if I'm doing cardio (heart pumping, breathing heavier, sweating a lot
)
Am I just not trying hard enough, am I just a bit slow or do I just have a kind of slow beating heart, even in exercise?
What is everyone else's heartrate after running, say 20 mins? After 20 mins running my heart rate was 115 today
I have a feeling i may just not be as fit and active as I think haha
