Another gym post

This was a long enough workout that, eating lunch afterwards, I thought "I hope that proved whatever I was trying to prove." One possibility: demonstrating my elbow had recovered from the diagnostic stuff the physical therapist did yesterday. That said, I was cautious: I spent almost two hours at the gym (including time to shower and such, but significantly longer than usual) but emphasized lower body and core stuff.

After today's cardio exercise, I am wondering about target heart rate: at what point, if at all, do I look at the machine's measurement of my heart rate and say "this is too high" and ease off? As far as I can tell, there are two questions here. The first is whether there is a "too high" and if so, what it would be in my case. The second is, are the monitors built into the gym's cardio bikes accurate enough to do anything with? (Numbers under cut tag.)

Also, the Mid-Manhattan Library is a reasonable walk from the gym, so an okay place to have the library system send me books. (I had been having them sent to Science, Industry, and Business, which is three blocks from my old office.)
