What is a Bro split?

A "Bro split" in weight training is a type of workout routine where you focus on one muscle group per day. This approach allows for a high concentration on each muscle group and can be appealing due to the intensive "pump" that it provides, which feels satisfying and enhances muscle aesthetics more prominently than overall strength.

For instance, you might dedicate one day solely to biceps, another day to chest, and continue this pattern throughout the week, focusing on different muscle groups each day. While there are scientifically more efficient methods for strength training available today, the Bro split remains popular for those aiming for aesthetic improvements and who enjoy this focused approach to their workouts 1 .
