- I guess that we have a difference of opinion on what exactly it is that
- constitutes the anaerobic threshold..... oops, silly me, I just answered
- my own question :-). That line in my previous post should have read
- something like:
-
- Mind you, these folx must stay below THE POINT OF ANAEROBIC FAILURE
- during a workout (or a race, for that matter), because if the legs
- pump up, the legs will quit. (also, if you go too deep into oxygen
- debt, then you will have to quit)
