p.s. I re-read your original message and it leaves me wondering if the HR data from anaerobic exercises (lifting weights, doing squats, running 100m, etc.) should be interpreted differently than that of aerobic exercise (cycling and running at "normal" pace). We need an exercise physiologist here!

And, by the way, if you doc told you "you have the heart of an old woman" at age 35 THAT would be a problem. I'll take a juvenile heart any day.
