So now it is chin ups instead of pull ups?
As some guys have wrote train both variations.. you might just have to do pull ups which are harder for most people. I have always been stronger in pulling movements than pushing. I lift my body up to a sternum chin. It´s different to a normal chin up or pull up.
Yes, according the article. Doesn't make a huge difference.
It does as the biceps are much more involved, in lat training you can bring your elbows further back (sternum chins) & this is why Dorian yates did supinated Barbell rows for lower lats although I don't believe in isolating any part of a muscle. Chins in my opinion are better for me as a lat builder.
I'm sure you have that back to front mate.
Yes supination is inner hand facing as a chin up. I remembered this as eating soup palm inward hence supination when doing my trainer licence..lol.
Also this notion that a wide grip will give "wide" lats is not true, what it will give is a shorter range of motion. I never use much more than shoulder width sometimes less.. more. range of motion thus TUT, time under tension. More time under tension is more stimulation. Ex-Pongo is fully correct in what he wrote so knows his training. Well, he's a Scot what can I say?
