One of my very first blog posts featured those pull ups along with this classic video
Both got online hate at the time, and both are worth appreciating that, when these folks say “chins/pull ups” and THIS is what they do…why would we do them differently than this?
From a competitive bodybuilder’s perspective the one whose scapula has great movement necessary for a good lat spread is difficult to criticize.
They ended up transitioning from powerlifting into bodybuilding. It was a fun journey to follow.
Yeah, but compared to like The Hulk or something, he’s kinda twerpy.
Or horses. Horses are pretty jacked and they can’t do any pullups.
KK is a legendary icon… RIP.
“This is my fucking belt”
Obviously full range of motion isn’t needed for muscle growth. Jay Cutler didn’t use full ROM on several exercises.
I consider the form and reps in these videos inefficient though they are effective. There are things out there worth hating; others’ exercise form isn’t one of them. Lol.
I don’t know if it’s wise to mimic the elite in all examples. (As an aside, Kroc said numerous times he has piss-poor genes yet no one with piss-poor genes can have his accomplishments.)
I prefer a full ROM and added weight, moderate reps (5-8) on pullups and chinups, as I do on most exercises, because I like the way those feel, and they’re efficient. Plus I feel cool on the occasions when I decide to take my lower chest almost to the bar and lean back slightly with a hollow-body position. 
It feels awesome.
This seems a bit “no true scotsman” for me.
I prefer a full ROM
Speaking of philosophy…
What if what we’re seeing IS a full ROM: just of a different exercise? For example: I use elevated deadlifts in my training. One could say that I am doing partial ROM deadlifts, but am I not, instead, doing full ROM partials? Or, in turn: doesn’t that mean that the deadlift ITSELF is a partial movement, because I could always stand on an elevation and make the ROM even MORE fuller.

An excellent point: what you’re describing is the Vince Gironda “sternum pull/chin up”, and, in turn, doing the full ROM of that. Which would mean a traditional full ROM chin up is actually just a partial sternum chin up.
Which is why I say it’s worth seeing what these dudes are doing and wondering WHY they’re doing them.
In that sense, yes.
You’re right.
Everyone has been doing lengthened partials this whole time!?
+1 for the nerds?!
It’s like when I would cheat at Dungeons and Dragons when I would play a half-orc, where the other half was orc.
“Isn’t that just a full orc?”
“No you idiot: it’s two half-orcs. I get twice the bonuses!”
