The landmine split jerk is a rotational movement training (RMT) exercise, which means that it helps to develop the ability to generate and transfer power through the core through spinal flexion, extension, and rotation. 

The landmine split jerk develops a strong core to maintain balance and stability throughout the movement. A strong core is foundation for all movement. 

Lower body strength: The landmine split jerk also works the muscles in the lower body, including the quadriceps, hamstrings, and gluteus muscles. 

Coordination and balance: The landmine split jerk is a complex exercise that requires a high level of coordination and balance, which are important for all types of physical activity, including sports, exercise, and everyday activities.
