Do you have links to similar sites for Carmichael's and Friel's Zone calculations?
Friel:

Find the row where the number in bold is your LTHR.
Karvonen method:

Can't remember where i last saw Carmichael's.
Note the large differences between these methods and the %HRmax method from the original post, especially in the low zones (1 & 2). The descriptions of the zones, however, tend to be similar. This is clearly not an exact science.
