Important lifts aren't always impressive.
In fact some of the most important work in the gym looks really boring or goofy.
If you're a bro that likes to bench Press or overhead Press or do lots of tricep and chest work, you NEED to do lots of rear delt work.
Not only will it give you a more balanced looking physique, but it will also help keep your shoulders healthy and safe. That way you can bench for decades and not just years!
