I'm not sure how long it takes actually. I'd say for the set of 12 about a minute, and maybe even similar for the 20 reps as the weight is lighter. However, I can't say actually. It doesn't really feel that long as time ceases to exist to me in those moments. I should film to check but I just started at my new gym, and it's a bit crowded. I don't want to have to worry about someone stepping in front of my phone during a set, or have to be rude and be like "hey people, who've been going her longer than I, everybody watch out I'm filming".
As for breaths, it's usually one until the last few reps. With the 20 rep squats, I usually slow down to a few breaths at 15 reps and with the 12 rep squats, usually at 9 reps it seems. So about 75 % into the set. I think part of the benefit of high rep squats, is the length. Holding the bar on your back may "help" you recover for the last rep, but you're also usually gasping for air...with a considerable amount of weight on your back. I think this was the "secret" in old time bodybuilding you refer to. That "breathing" under a load with a posture that back then was a little more pretty, as the squats they recommended for 20 rep squats were usually with no more then BW on the barbell and a higher bar position. Usually, the breaths would be large long inhales and exhales, and this was thought to "expand" the ribcage, along with pullovers done between sets. I'm sure it has some pretty profound effects on lung strength, as you are not merely catching your breath but taking in large inhales.
True, holding the bar on the back may allow us to grind more, but in the deadlift it's better....we get to use the floor! And in the press, our shoulders like a front squat with considerable less weight or at arms length in the bench. Alas, smaller muscle groups are responsible for the latter two lifts and the press/dl don't get the benefit of stretch reflex, at least for the first rep for presses. I don't bounce my deads.
I also note the when I do pretty heavy/low rep sets, I tend to take my time between reps, as do many other powerlifters I've trained with. they'll hit one grueling rep, breath and rest at the top for a moment, hit another slow grind and after I assume they're about to re-rack, they'll stand there for moments...breathing...waiting...jeopardy theme...and hit one last all out rep. So in essence, the last few reps of my high rep sets aren't so dissimilar to a regular set of heavy 3's or 5's. In my case, I think I get more tired in the lungs, then in the legs. I have a loooong squat, and I think I'd shortchange myself the strength gains by allowing my breath to be the limiting factor.
I also think another benefit of 20 rep squats is not only TUT, but the mental toughness aspect. It's quite grueling. I think the lower body seems to respond better to high rep work for some reason as well. I won't get into fast/slow twitch stuff, but high rep lower body work has been working pretty well for me. Also, one can't discount how hard the core and back must work throughout this whole thing, even at the top at "rest".
Sounds like our ways around the high rep squats are pretty much alike.
McCallum, the man, writes about the load: "You've got to work up into the 300 to 400 pound range for anything really spectacular.". I love a clear cut challenge like that.
The hard 20 rep squats really do build character. Everything's a breeze after them.
