Um, no, dipshit, re-read what I wrote.
The angle and positioning of your upper body throughout the movement has a significant effect on how much you involve the lats relative to the bi’s.
Any good strength/physique coach (including those on this site) will tell you, when doing almost any type of lat exercise (rowing of various kinds, pullups, pulldowns, etc.) that, in order to try to target/isolate the lats as opposed to using the bi’s too much, you must arch the back and stick the chest out.
This is not in dispute. Doing the opposite WILL use the bi’s more and the lats less.
Perhaps instead of “lat” width builders I should’ve more broadly referred to them as “back” width builders because yes, they build the lats, and the lats do indeed grow outward (“wide”). This is as opposed to other back excercises, like certain types of rows, which perhaps target the lats themselves a bit less and the other muscles of the upper and inner back a bit more, which builds a bit more “thickness” in the back than width.
Wow, in one post you proved yourself to be both wrong and a complete asshole. Nicely done.
It depends how you do them. Likewise, dips on parallel bars can be tweaked to focus more on the tri’s or more on the pecs, depending on what you’re aiming for.
If you do your chins with a fairly close grip (shoulder width or closer) don’t arch your back much or stick your chest out much, and focus on using your bi’s and really squeezing them hard in the top position, then they target your bi’s a lot.
If, however, you use a shoulder width or slightly wider grip, focus hard on keeping your back arched and your chest stuck WAY out (especially as you near the top of the range of motion) and squeeze the lats hard at the top, trying to envision your hands merely as hooks and your arms merely as “connectors” and not “primary movers,” then you’ll target the lats much more. If you do them that way, they’re a great lat width builder – perhaps the best.
so your saying ‘squeezing’ your bi’s would really take the emphasis off the lats and place them on the bi’s?I don’t think so. A big back arch and a chest stuck out will not alter the emphasis between the lats,bi’s and forearms. Finally, I like the part you wrote about the style you described for pullups as being lat ‘width builder’. as opposed to pull ups being what else? for the most part, when the lats grow, they grow out wide. Besides width, back growth in this area of the back is attributed to other muscles undergoing hypertrophy ( ie. teres minor & major, plus the rhomboids).
To the other posters, the majority of the difference between pull-ups and chins has nothing to do with the lats, it’s basically a difference placed between the biceps and the muscles of the forearms.
