I have no idea what you guys are talking about regarding acid baths or whatever. All boxers run different and all types of running seems to work. Duran and Tyson for example ran long slow runs. Duran had great stamina all of his career. Jake LaMotta hated running, but used to spar 8 four-minute rounds with only 30 seconds inbetween rounds. And Jake had great stamina. Ali also did long slow runs and he too had great stamina. I am not sure this is one right way to run. Norton used to mix wind sprints into his running.
