bro split
A type of weightlifting routine performed by uninformed bros. It consists of separate days for separate body parts. The focus is typically on biceps and chest because those are the only muscles that matter to bros. A typical bro split might consist of Monday (Back/Biceps), Tuesday (Chest/Triceps), Thursday (Shoulders), Friday (Legs (often skipped by bros)). The bros often just do a machine circuit not really having any clue as to what or how they are training. Good form is often hard to find.
Going back to the University gym after the holidays is going to suck with all the frat guys doing terrible bro splits for their new year's resolution, but it should die down after Martin Luther King Day.
