A workout split refers to how you divide your training routine throughout the week, typically focusing on different muscle groups or movements on different days. The most common workout splits include full-body workouts, upper/lower splits, push/pull/legs splits, and body part splits. Each split has its advantages and is tailored to individual goals, preferences, and training experience.

The best workout split ultimately depends on your fitness goals, schedule, and preferences. For beginners, a full-body workout split done 2-3 times a week can be effective for building overall strength and muscle mass while allowing for adequate recovery. More advanced lifters may benefit from splits that target specific muscle groups or movement patterns, such as push/pull/legs or body part splits, allowing for more volume and intensity per muscle group. Experimenting with different splits and adjusting based on progress and recovery is key to finding the best fit for your goals and lifestyle.
