My gym has a few stationary bikes with heart rate
monitors built into the handles.. I never did any pulse
rate readings before, so I thought I'd try it.
I can't get my pulse above 145 bpm. It takes about
4 minutes to raise it there, then it gets stuck.
Yesterday, I glanced at a couple of girls beside me,
they were at 170, same bike.
What's going on?
