Then building training zones around the LT number is very straight-forward - for example, you can train in a zone that's 80% of your LT, or 90% or whatever you choose for your goals. This is the method used by Joel Friel and others of ultrafit - a pretty respected coaching outfit in the US.
Would you please explain how this works? I am quite interested because using my HRM, I am almost always working above my 85% MRH-and honestly am not winded. (I am using the 220-age formula). I sort of get what you are saying, but I would prefer to understand so I do it correctly.

TIA!
