We, modern-day humans, have lost the need and ability to adeptly manipulate our body weight on the vertical plane. Regularly doing some pull-ups (or chin-ups) is a very effective way to regain that ability, not to mention that it will sculpt some great lats.
Don’t worry if you haven’t done a pull-up in years (or ever). I understand that starting this activity as an adult takes more than just simply buying a bar and doing it. That is why I suggest starting with some simple hanging “shrugs” before moving on to an eccentric (or lowering) movement before trying to do a full pull-up. I demonstrate all of those in this video!
