Eric Roberts shows why pulling the lat pulldown bar too far down past your chin kills the exercise. It rounds your shoulders forward and shifts work from your lats to your biceps. Stop at chin level and drive your elbows down toward your hips instead.
If I was in the gym and I saw you doing lat pulldowns like this, I would absolutely help you out and correct you. And the mistake you are making is you are pulling this bar way too far down. And what happens when you do this is you round your shoulders forward and it causes you to bring your elbows too far back, which ends up working more of your bicep and less of your back muscles. So next time I want you to stop right when this bar gets below your chin. Level. And I don't want you to think about driving your elbows back. I want you to think about driving your elbows down to the top of your hips instead.
