Hi guys. I like to read a lot of theory about training and stuff like that, i find it interesting to know how our body works and how it reacts to training.
Anyway, yesterday i read something on a forum that i had never read anywhere else, they were saying that 1 hour of L4s training in a relatively untrained person would improve FTP by ~2 watts.
Is this true? if yes then someone who builds a good base would be able to improve at a faster rate and plateau at a higher level right?
