The pullup is the #1 best exercise for building wide lats. In this video I’m going to show you the proper form to build cobra-wide lats. Just a note here, there are many pullup variants that have goals other than building really wide lats. I’m focusing here on the form you want to use if you want to target lats and build your lats as wide as possible for a great V taper.
If you cant do a single pullup, then please start with pullups for beginner in a previous post.
