Dorian Yates trained 4 times a week and won Mr Olympia 6 times in a row. You donât need to train the same muscle every single day.

These people are not only genetic freaks but also on a lot of drugs. It's not just steroids and testosterone but also drugs to stimulate hunger for growth. It doesnt make sense to compare their results to natural people with ordinary genetics. Mike Mentzer only trained twice a week and that was enough for a drugged up freak like him. Without steroids and crazy genetics, ordinary people simply need to workout properly and get sufficient time to recover.
I knew someone would jump in with this bs and waste my time again. Itâs like you live your whole life on âAcktchuallyâ mode, always needing to chime in based on picking and choosing keywords for âgotchasâ, which in this case, arenât even relevant.
âAnd get sufficient time to recoverâ is the point here, which you didnât even address.
YOU CANâT TRAIN THE SAME MUSCLE EVERY SINGLE DAY
