    I'm surprised there's no thread on this:

    Apparently, only 60% of the subjects made gainz to 12 weeks.

    But I see it looks like they only gained but a few kilos of body weight.

    Can not ANYONE, DTFP? jeesh!

    Yeah, they fucked with John's protocols to the extent that the study was standard ExFizz nonsense. Not his fault, I assure you.

    Looks like by allowing participants to ignore The First 3 Questions. Participants were told to eat as they normally would, determine on their own their rest between sets, and determine their load progression. Participants also determined training frequency, and I may have missed it but I also didn’t see sleep/rest mentioned, other than the note about minimizing other sports stuff.

    The one person who dropped out from injury did so because of medial epicondilytis. Couldn’t that have been from a bad arm position in the squat? Should the study have mentioned either that the coaching/form observance ruled that out or at least allowed for the possibility that it was related to/caused by this person squatting? Am I wrong about the injury?

    "choices regarding rate of linear
    progression, frequency of training (2 or 3 non-consecutive d·wk
    -1
    ), and rest between sets were
    left to the discretion of the subjects"


    That said, I thought it was interesting that the subjects that chose the higher rate of progression were NOT less likely to fail out...
