@goliathliftzz: Before, we had “more sets = more muscle” and the whole system believed in that. Then, a completely different philosophy appeared, saying the complete opposite. Heavy duty training is known to be the one that separates strong and weak. Perfect form, absolute maximum intensity, until complete muscular failure. If you thought you were done with your set, think again. Forces reps, brutal intensity and discomfort from experiencing it. Few bodybuilders could actually endure it. Do you think it works or do you believe more sets are better? #trainhardorgohome #mikementzer #oldschoolbodybuilding #bodybuildinghistory #hardcoregym
