@ayn Depends upon which you can perform better. When I did #2 for the first time, I didn't feel my lats, rather mostly biceps, so I stuck with normal lat pull. Later on I learned the form for #2. It might be the same for you.
@jenfer yea today i did the #2 one and felt my biceps more so stopped after second set, the gym is usually empty when I go so I stick with exercises that I have grip on
@ayn Number 1 is what I meant by neutral grip pull-down.
But my intent of recommending this exercise is for you to target you lats which will not be the case if you do it like it is shown in the picture. You would want to keep your elbows closer to the body for better lat engagement.
