The split jerk is a compound movement that works almost every muscle in the body. It involves lifting a barbell from shoulder height to overhead while splitting your legs into a split stance. This movement is commonly used in weightlifting competitions as it provides more stability and control, allowing weightlifters to lift heavier weights. The split jerk can be beneficial for those looking to build explosiveness for sports or thicker traps. It also helps to build core strength and stability, shoulder strength, and overall mobility in the wrists and shoulders.

What You'll Learn
Hamstrings, glutes, calves and posterior chain
The split jerk is an athletic lift from Olympic lifting that involves nearly every muscle in the body. It is a compound movement that requires a lot of steps to perform flawlessly. The movement involves getting under a barbell from a front-racked position, then dipping and driving more weight overhead. The feet placement is the key difference between the split jerk and the push jerk. From the dip, the dominant foot will jump forward, while the opposite foot will drive back, catching the bar overhead in a locked position, resulting in a split stance.
The split stance places more emphasis on the hamstrings, glutes, calves, and the entire posterior chain. The hamstrings, located on the back of the thigh, are responsible for knee flexion and hip extension, which are crucial for the dipping and jumping motions in the split jerk. The glutes, or the muscles of the buttocks, are also engaged during these movements, providing power and stability.
The calves, located at the back of the lower leg, are involved in ankle flexion and extension, which are essential for maintaining balance and stability during the split jerk. The posterior chain, which includes the muscles of the back, is engaged throughout the movement, providing support and stability to the spine and core. These muscles help to keep the body stable and upright during the split jerk, especially during the dipping and jumping phases.
Overall, the split jerk is an excellent exercise for building lower body strength and stability, as it targets the hamstrings, glutes, calves, and posterior chain muscles. It is a complex movement that requires practice and perfect technique to master, but it can lead to significant improvements in athletic performance and overall body strength.

Quadriceps, back and trapezius
The split jerk is an athletic lift from the sport of Olympic lifting. It involves a tremendous amount of compound muscle recruitment and activation, working almost every muscle in the body.
The quadriceps are crucial for the split jerk. The four quadriceps, namely rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius, are located on the front of the thigh and work together to extend the knees. A person's ability to get out of the split jerk is directly correlated to the strength of their quadriceps.
The back muscles, particularly the lats, are also engaged during the split jerk. They are essential for keeping the body in an upright position during the front squat and providing stability during the jerk.
The trapezius, or traps, are another important muscle group. They are targeted by the explosive nature of the split jerk and are crucial for achieving a stable overhead position. The traps also contribute to the overall stability of the movement.

Shoulder muscles, triceps and biceps
The split jerk is a highly complex, dynamic exercise that involves almost every muscle in the body. It is a full-body exercise that combines a dynamic lunge with an overhead press. It is a challenging exercise to master, requiring patience, skill and time.
The shoulder muscles are critical in the split jerk. The deltoids, or delts, are the major shoulder muscles that are targeted. There are three sets of deltoid fibres, or heads: anterior (front), medial (side) and posterior (rear). All three groups are involved in the split jerk, but the anterior is the most dominant, while the medial and posterior act as stabilisers. The shoulder muscles work isometrically to keep the weight from moving overhead.
The triceps, located on the back of the upper arm, are responsible for extending the elbows. During the split jerk, the triceps help to lock the arms straight. The triceps are considered part of the supporting muscles of the arms that work the hardest during the exercise, along with the biceps.
The split jerk also works the trapezius and rhomboids, which cover the upper back between and across the shoulder blades. Their main job is to stabilise the shoulder girdle by holding the shoulders down and back.

Core strength and stability
The split jerk is a complex, full-body exercise that involves a dynamic lunge with an overhead press. It is a compound movement that works almost every muscle group in the body, including the core.
The split jerk also targets the abdominal muscles, which are essential for maintaining a rigid torso and generating power during the lift. Additionally, the gluteal muscles, particularly the gluteus maximus, play a crucial role in hip extension and stability, preventing the knees from collapsing inward.
To improve core stability in the split jerk, athletes can focus on exercises that target the abdominals, obliques, and glutes. For example, ancillary lifts and resistance training can help build core strength and stability, which will translate to better performance in the split jerk and other weightlifting movements.
Furthermore, the split jerk itself can be modified to focus more on core stability. One variation involves pausing just after the dip in a shallow squat position to improve strength and stability in the bottom position. This variation can also improve shoulder flexibility and provide a different stimulus for the muscles.

Full-body strength and power
The split jerk is a full-body exercise that involves nearly every muscle in the body. It is a compound movement, meaning it actively recruits several muscle groups, conjoining secondary muscles, stabilizers, and joints. It is an explosive movement that requires strength and explosiveness.
The primary muscle groups that are engaged in the split jerk movement include the hamstrings, quadriceps, deltoids, triceps, trapezius, rhomboids, and core muscles. The hamstrings and quadriceps are responsible for extending the hips and knees, respectively. The deltoids are the major shoulder muscles, with all three groups of deltoid fibers (anterior, medial, and posterior) involved in the split jerk. The triceps help to extend the elbows and lock the arms straight, while the trapezius and rhomboids stabilize the shoulder girdle. The core muscles act as a weightlifting belt to stabilize the lumbar spine during the movement.
In addition to these primary muscle groups, the split jerk also engages the back muscles (lats) and the glutes. The leg drive is the primary source of the jerking motion, but the shoulders also play an important role in keeping the weight from moving overhead. The split jerk can be challenging to perform correctly, but it is a valuable exercise for building full-body strength and power.
The split jerk is a common exercise in Olympic weightlifting, where it is used to improve the ability to lift heavier weights overhead with greater stability and control. It is also beneficial for athletes looking to increase total-body strength and power, improve coordination and timing, and develop explosiveness for sports. The dynamic lunge and overhead press combination of the split jerk makes it a unique and effective exercise for those seeking to improve their full-body strength and power.

The split jerk is a full-body exercise that works out nearly every muscle in the body. This includes the quadriceps, hamstrings, glutes, calves, shoulders, triceps, core, upper back, and trapezius.
The split jerk is a variation of the jerk that is commonly performed in Olympic weightlifting and athletic training facilities. It differs from the squat jerk and power jerk in that the bar is received in a lunge position. This places more emphasis on the glutes, hamstrings, calves, and the entire posterior chain.
The split jerk improves shoulder strength, stability, and flexibility. It also improves core stability, overall balance, and coordination. Additionally, it helps build strength and power by challenging and engaging every muscle.
The split jerk can be performed as many times a week as needed to work on specific qualities such as strength, power, or speed. It is important to pay attention to recovery and rest to prevent injuries and allow proper muscle rest.
