Here what I got:
So apparently my heart rate only hovering within 150-160 range. Not even sure if I'm in my target zone or not. Btw, if our heart rate is high when we're exercising does that mean a good thing or bad? For example, our heart rate is not that high but you burn lots of calories versus higher heart rate and burning the same amount of calories. This matter still confuses me.
Also when I was jogging, I saw this middle age man, jogged at similar pace or even faster than me. I couldn't really pass him but I wasn't that far behind him either. Man, I gotta increased my endurance more.
