So I was jogging on a treadmill today, as part of Couch-to-5k. Based on my age (30), my max heart rate is 190. I used to start to feel yucky at around 180 (my chest would get sore, and I would immediately slow down). But today I was up at 185 for a few minutes and felt fine.
So.....
What happens if I hit 190? Will I like, self-destruct??
Do you think it's okay to work at nearly 100% if I feel okay?
Please understand, I am not *trying* to overwork or max out or anything like that. It's just that I can't keep jogging without my HR climbing "too high".
BTW, it goes back down to a nice 120 after a couple minutes of walking. And I use a Polar HR monitor that goes around my chest, so I think it's pretty accurate.
Thanks!
