A workout “split” is a method of dividing training sessions throughout the week, assigning specific muscle groups or movement patterns to different days. The Push Pull Legs (PPL) split is a popular and effective training methodology that organizes exercises based on the mechanical action performed. This approach simplifies programming and is widely used by individuals seeking muscle growth and strength development.
Structuring the Push Pull Split
The Push Pull Legs split divides all major muscle groups into three distinct training days based on the type of movement they perform. This structure is centered around the natural biomechanics of compound movements. The logic behind this grouping is that muscles that assist each other during a movement are trained together on the same day.
The “Push” day involves muscles used to push weight away from the body, primarily targeting the chest, the anterior and medial deltoids of the shoulders, and the triceps. Common exercises include the bench press, overhead press, and triceps extensions. This grouping ensures that all primary movers and secondary synergists for pushing movements are stimulated in one session.
The “Pull” day focuses on muscles that draw weight toward the body, including the large muscle groups of the back, the biceps, and often the rear deltoids. Exercises like rows, pull-ups or lat pulldowns, and various bicep curls form the foundation of this workout. Finally, “Leg” day is a comprehensive session dedicated to the lower body, including the quadriceps, hamstrings, glutes, and calves, with exercises such as squats, deadlifts, and lunges.
Mechanism of Effectiveness
The effectiveness of the PPL split for promoting muscle growth, or hypertrophy, stems from its ability to maximize training volume and optimize recovery management. Hypertrophy is strongly correlated with the total volume of work performed (sets, repetitions, and load). By grouping related muscles, the PPL split allows for a high total volume per muscle group without requiring excessively long individual sessions.
The strategic grouping also manages muscle fatigue efficiently by allowing indirect muscle groups adequate rest. For instance, after a demanding Push day, the triceps are fatigued, but they receive a complete rest during the subsequent Pull day, which instead taxes the biceps. This separation prevents overlapping fatigue, ensuring that each muscle group is fresh and capable of performing maximally when it is directly targeted again.
The PPL structure naturally allows for a high training frequency, which is a major factor in stimulating muscle gains. Research suggests that training a muscle group at least twice per week is more effective for hypertrophy than training it only once. The three-day cycle of the PPL split makes it simple to implement a twice-per-week frequency by running the cycle twice, such as in a six-day training week.
Implementing the Split for Different Frequencies
The PPL split offers significant flexibility, allowing it to be adapted to different weekly schedules and experience levels. The most basic application is the 3-day PPL split, where each of the three workouts is performed only once per week. This model is well-suited for beginners or individuals with limited time, as it ensures a full week of recovery for each muscle group before it is directly trained again.
For intermediate and advanced lifters, the 6-day PPL split is often preferred, as it maximizes the training frequency. This involves performing the entire PPL cycle twice in a week, typically following a schedule of Push, Pull, Legs, Push, Pull, Legs, followed by one rest day.
The 6-day structure is demanding but aligns with the principle of training a muscle group two to three times per week. Variations also exist, such as a 4-day rotating split, where the three workouts are performed over four training sessions. This adaptability makes the PPL split a viable option for nearly any individual.
Suitability Compared to Other Training Routines
The Push Pull Legs split is considered a highly effective routine for intermediate and advanced lifters who can handle a higher training volume and frequency. It provides a more structured approach than a Full Body routine, which targets all major muscles in a single session, often limiting the total volume dedicated to any one area. Full Body workouts, typically performed two or three times per week, are better suited for true beginners seeking to establish movement patterns and build foundational strength.
Compared to traditional Body Part Splits, which dedicate an entire session to a single muscle group, the PPL split offers better training frequency. Body Part Splits typically train each muscle only once per week, which is suboptimal for maximizing muscle growth. The PPL split, especially in its 6-day format, allows for each muscle group to be trained twice weekly, aligning better with the frequency required for consistent gains.
The PPL routine also manages the fatigue of synergist muscles more effectively than traditional splits, preventing issues like training shoulders the day after a heavy chest workout. Its functional grouping by movement pattern makes it a logical and sustainable program for those focused on muscle hypertrophy and strength development. As a result, the PPL split serves as an excellent progression for individuals who have outgrown beginner Full Body routines.
