What does split mean in gym?


If you’re new to the world of fitness or have recently started a gym routine, you might have heard the term “split” being tossed around. Split training, also known as a split routine, is a popular approach to structuring workouts in the gym. In this comprehensive guide, we’ll delve into the concept of split training, explain its benefits, provide examples of different split routines, and offer scientific insights into how it can help you achieve your fitness goals.

What Is Split Training?

Split training refers to a workout routine that divides muscle groups into specific training sessions on different days of the week. Instead of targeting all muscle groups in a single workout (known as full-body training), split training allows for focused and intense workouts for particular muscle groups during each session. The idea behind split training is to provide adequate rest and recovery time for each muscle group while optimizing training intensity.

Benefits of Split Training

Split training has gained popularity among fitness enthusiasts and bodybuilders for several reasons:

  1. Muscle Recovery: By targeting specific muscle groups on different days, split training allows those muscle groups to rest and recover between workouts. This can reduce the risk of overtraining and injury.
  2. Greater Training Intensity: Focusing on fewer muscle groups per session allows you to exert greater effort and intensity on those muscles, potentially leading to more significant muscle growth and strength gains.
  3. Variety and Focus: Split routines provide variety in your workouts and allow you to pay closer attention to specific muscle groups or weaknesses.
  4. Customization: Split routines can be customized to align with your fitness goals, whether you aim to build muscle, increase strength, or improve endurance.
  5. Time Efficiency: Some people find that split routines are more time-efficient because they can complete targeted workouts in less time compared to full-body workouts.

Types of Split Training Routines

Several types of split training routines exist, each with its own focus and structure. Here are some common examples:

1. Push-Pull-Legs (PPL):

  • Push: Targets chest, shoulders, and triceps.
  • Pull: Focuses on back and biceps.
  • Legs: Concentrates on lower body muscles, including quads, hamstrings, and calves.

2. Upper-Lower Split:

  • Upper Body: Divided into two days, one for chest and triceps and the other for back and biceps.
  • Lower Body: Two separate days for leg muscles.

3. Body Part Split:

  • Each day is dedicated to a specific muscle group or body part, such as chest, shoulders, back, legs, and arms.

4. Three-Day Split:

  • Divides the body into three sections, often focusing on upper body, lower body, and a day for core and cardio.

5. Five-Day Split:

  • Targets specific muscle groups or body parts each day, allowing for in-depth training and recovery.

Scientific Insights

Split training aligns with the principles of periodization, a scientifically-proven approach to training that involves varying workout variables over time. Periodization can enhance muscle adaptation, strength gains, and overall performance. Split routines also promote the concept of progressive overload, where you gradually increase resistance or intensity to stimulate muscle growth and strength development.


Split training is a popular and effective approach to structuring workouts in the gym. By targeting specific muscle groups on different days, it allows for optimal recovery and training intensity, contributing to muscle growth and strength gains. The type of split routine you choose should align with your fitness goals and preferences. However, it’s essential to remember that consistency and proper nutrition play crucial roles in achieving your desired fitness outcomes. Always consult with a fitness professional or trainer to ensure your split routine is tailored to your individual needs and abilities.
