What's your max HR?

[Eden]

I read something a while back about people whose resting HR was below 40, needing to take caffeine to keep their resting HR at a level that will supply enough oxygen to the heart and brain tissues. That's not me... I don't know my true resting value, but when I just lay around for a while it's in the mid to low 50s... but I think I'd worry if mine got TOO low.

Heck no - my husband's resting rate is waaaay low - sometimes his polar monitor shuts off because it thinks its not getting a signal, so it may even get into the 20's sometimes (polar shuts off under 30......) He can be sitting and talking to someone and be in the 40's - it kind of freaks them out somtimes when he gives blood, but its totally natural for him.

Miguel Indurain (famous cyclist from the 90's) had a resting rate of 25!

I was just thinking - I'm not a runner so I don't think about running max much, but my cycling max is 211- so concievably (I've never run until I wanted to puke....) since your running rates are possibly 10 beats higher than your cycling rates I could get a legitimate reading of 220....
