When it comes to working out on the bar, you often see individuals performing complex moves that test the boundaries of human strength. However, you don't necessarily have to try anything quite as daunting to get amazing results.
It all boils down to the basics - muscle ups, dips, and pull ups. As demonstrated in this video here, if performed only a few times per week, this simple superset is sure to provide stellar upper body development. Once these become easy, there are many different variations you can attempt. Happy training!
