A “bro split” refers to any workout routine (or “split”) that trains different body parts (or muscle groups) on different days. For instance, training arms one day, chest another, shoulders another, and so on.

Why do they call it a bro split?

The Origin of Bro Splits

When Eugen Sandow and the first great wave of physical culturists helped ignite interest in gym cultures in the early 1900s, they did so largely on the back of full-body workouts. That is, as the name implies, when you train your entire body each session.

What's better PPL or Bro split?

The PPL split is great for making your whole body grow, but if you specifically need to improve shoulder caps or biceps or triceps, you may well be better off incorporating the bro split for those areas.
