I have issues with my neck - pinched nerve, and I have to not jar things around too much.
I run 7 days a week and lift 3 times a week, and stopping cold turkey is hard.
So, I turned the treadmill to 10 degrees and 4.3 mph, that's as fast as I can go and still be walking instead of needing to break into a trot.
I was happy to see that I could get my heart rate satsifyingly high that way - after 45 mins I was at 174 bpm, and my max is around 185 or 190, so that's a decent sweat for me.
Anyway, if I run for 45 mins and I shoot for 170 bpm, I am breathing hard.
With this workout, I wasn't breathing nearly as hard as if I were running at the same pulse rate. I didn't feel as tired either, but I was sweating roughly as much, I think - that's sort of hard to tell for sure.
Why is that? Shouldn't my resp rate be pretty linked to my pulse rate regardless of whether I am walking briskly up a hill or running over flat ground?
