I personally think your fine. I'm relatively conditioned so I'll try the treadmill if my recent knee injury isn't feeling that bad, and see what my heart rate is, I can comfortably run/jog for about 45 minutes. I never really check my heart rate because the machine chastises me for doing so while running but I know it's reached around 160 at max running speed although that was a few years ago, resting is 50-high 60's, although it did reach around 70 recently but I wasn't really rested. I'll try it tonight if it makes you feel any better.
You aren't reading my posts, ive told you two times what my resting heart rate is.
usually 80's, so it goes up to 120's walking. Normal or no?
Sorry, I edited my post after I read yours again. Just back, resting HR at this exact moment is 73. Anyways.....
I was walking for about 5 minutes just to check it out, it sad my heart rate was around 120. I checked myself, counted for 15s x 4, it was 96. I started jogging [9min/mile pace], 30 minutes into it the HR monitor reached 180, I let go of the metal sensors, it reached 210 without my hands on it. I had trouble checking my heart rate manually while jogging/running.
Ask your PCP to refer you to a cardiologist if it makes you feel better, s/he'll probably do what mine did, as me why I was there since everything's normal, but hey maybe not. Best of luck!
