And lactate threshold isn't "real"....even doing it the "scientific" way with a lactate tester it's open to interpretation. You graph the results and look for where the slope changes.
ideally:
FTP is a measure of extrenal product of phisiological processes, or output.
LTHR is a measure of the phisiological work itself. its not a perfect measure, but i'm just asking if in the rush for new toys and new tech we might not be neglecting the value of listening to the body itself and not just the output?
