Gotta agree that HFT is better for strength gains, have experienced it myself first hand.
For hypertrophy though, doesn't seem to be the case for me, not sure why though.
It does make sense though if you do a lift say 5 times a week - bench every day or multiple times a day or squat.... and you stay in the 75-85 % range and hit failure too often, that progress would be superior to smashing a muscle once a week , 200 plus bench or squat sessions in a year at moderate weight would give you better results than say 50 - 75 high intensity workouts a year - no ?
You want to get good at something, do it a lot- swimmers, runners ... sometimes train multiple times a day EVERY DAY, has to be something to it -right ?
