Function of the lats: extend the humerus, and draw it towards the midline of the body.Lats originate along the spine, and insert in armpit.Many published studies on EMG show different fibers activate depending on the angle of the pull relative to the torso position to the resistance. So you can't activate, maximally, all lat fibers using one angle of pull. You need vertical pulling as well as horizontal pulling to activate all lat fibers and fatigue them. The "Yates row" has its part in a program just as the wide-grip pull-up. Different lat fibers are called into play. Just because fibers fire on an all-or-nothing principle, doesn't mean an entire muscle does. Angles of push/pull call different fibers into play. There's overwhelming amounts of scientific proof in published studies to believe any differently.Also poorly known, is that heavy deadlifts actually activate more peak and mean involvement of lat fibers in some areas of the back than rows or pull-ups. So complete lat development requires deadlifting for the average guy (note: Yates, Coleman, Haney are not average).
Well, maybe not dumbbell rows, but I always feel tbar rows more in my mid back. I feel like I can get a better squeeze when I use a narrow grip.And you might be correct about barbell rows being the only thing you need. However, realistically speaking, people would get bored only doing bb rows. I do them every workout, but I surmise people do other exercises to offset boredom. That's probably the main reason why.
So by your logic, since Gates was a college drop-out and later became a multi-billionaire and one of the world's most successful entrepreneurs, everyone should drop out of school and expect riches? Care to invest in my start-up? You can be an VC for just $100,000 - I promise ROI! Just because Levrone, one of the most genetically elite bodybuilders of all-time, did something, doesn't mean you can do it, nor can you rest your case. Unless you like losing.
For a good back.
