I only just started measuring heart rate on the bike and I'm reading Friel's book. I'm confused about the lactate threshold vs max HR thing. I did a ride today in the hills where my max HR on the computer was 180. Assuming I was going uphill at that point about as fast as I could have, would 180 be my *max* or would that be my "lactate threshold"? It matters because his zones are based on % of lactate threshold and other zones I find elsewhere are % of max HR. No, I'm not gonna use my age in the math.
Also, his zones don't take any account of resting heart rate. Isn't that important, since my resting HR will likely drop as I get more fit?
