if you’re trying to emphasize your lats, keep your forearms perpendicular to the ground throughout the entire range of motion.
Yeah, after you posted this I mimicked my bent-over technique and where I come up to–right in between the pecs and abs–has my arms at a 90 degree angle. I guess when I posted I wasn’t really thinking from a mechanical, universal point of view, just what’s worked for my short arms.
So yea, your definition works considerably better from a universally relevant point of view. Sorry about that.
out of curiosity, how far forward to you bend? how low does the bar go <past your knees, near the ground, whatever>?
here’s an easy way to look at it, bend over and let your arms hang as if you’re about to start rowing, peep yourself in a mirror from the side. so now you’re bent-over in the starting position with your arms hanging straight down to the ground and peeping your setup in a mirror placed to the left or the right of you.
now contract your lats and pulls your arms toward your torso. are your forearms still pointing straight to the ground?
my position is that the forearms must always be perpendicular/90 degree angle to the ground. the angle between the forearm and the upper arm changes throughout the range of motion though, from a 180 degree angle at the beginning of the exercise , and then close to a 90 degree angle a the conclusion of the lift.
i also think it’s a good idea to do every repetition from the ground. that way you get a break at the end of every rep and minimize extra volume for the lower back.
if you prefer a shorter range of motion, you can also go in a power cage/rack and set the pins to wherever you want <i.e. near your knees> and row every rep from the pins.
hope that explains where i’m coming from.
