I walk about 5 hours a day with my job. (Janitor) I can lift things sometimes and climb stairs, etc. My heart rate is weird though. When I’m resting it’s arround 53-56 bpm. I’m 29, 5’11 and about 155-160 lbs. thing is... just getting up it can spike to 90-110. So when I work. Walking going places to places it can go up to 130-140. The problem is when I climb a 3-4 flight of stairs, the thing can go as high as 160-170. I never really feel out if breath when I walk, but I do a little after climbing the stairs. It’s been like that for a little while now. I’ve had that job for years, been walking 4-5 hours for year, 5 days a week. Wondering if it’s “normal” or if something is or could be wrong. Also want to precise that I have a lot of anxiety and takes a small dose of medecine to help me with that. Thank you.
