I still find it hard to believe the amount of sets that some guys are doing. Even going as far back as the eighties the great Lee Haney said that you should only do enough to stimulate the muscle NOT annihilate it! Even Dorian Yates who was the first to take mass building to the current freakish level, did so, despite average genetics using H.I.T. with only one working set per exercise to total failure! IMO it makes perfect sense cos the more we learn about the body and how it works the more we realise how easy it is to overtrain and that we should work smarter not harder which is why virtually nobody does two hour workouts anymore!
I personally only work out three times a week ie. Shoulders and Arms, Chest and Back and Legs with only three sets per bodypart using compound exercises and maybe an isolation exercise as a pre-exhaust and I'm in and out in under an hour! But there are some massive guys in my gym some of which only work out twice or even once a week, their reasoning being that because they are stronger their workouts are more intense and so the body needs more recovery time and believe me the results speak for themselves! Their opinion of people who workout five times a week are that they are adrenalin junkies!
