One of best ways to see this principle in action is to do a set as you normally would with your normal grip for about 10 to 12 reps. When you can’t do any more reps, switch to grip as explained above. You should be able to get a few more reps out.

When using this grip you should also find that you can use a little more weight than you usually do for reps.

The reason this trick works is that having your arms straight removes your biceps as limiting link in exercise. It transfers force through your stronger back muscles instead, resulting in instant increased strength!

We will now do a rep with shoulder drop movement. Start in stretched position with your shoulders up by your ears. Drop your shoulders down, lean slightly back then do a pulldown. Be sure to keep your lower back arched and your chest puffed out to meet bar on way down. You should feel your lats working harder than usual.

Squeeze hard as though trying to touch your shoulder blades together as you come to bottom then let weight back up slowly. You can repeat shoulder drop movement at start of every rep or you can simply keep your shoulders down and locked in that position throughout set.

Dropping your shoulders down like this serves to lock lats into movement and helps to minimize biceps involvement in pulldown. You should find that you get a much more effective lat workout using this technique.
