Key Movements and Concepts

Mastering the folding pass involves understanding key movements and concepts that enhance mobility and the application of weight. The shin slice is a fundamental movement where the shin cuts over the partner's shin, either to the outside or inside. To execute this effectively, point the toes and knees in the direction of movement, press the partner's leg down parallel to the mat, and transition from heel to knee. Once the knee passes the hand, the body's weight maintains the leg's position, allowing for a smooth shin slice.

The forearm club is another essential technique, particularly useful in butterfly or half guard positions with a knee shield. Instead of pushing the leg with the hand, which uses smaller muscles, employ the larger muscles of the back and chest. Use the meat of the forearm to club the leg down, combining the motion with a downward shrug of the shoulder to transfer the body's weight through the forearm.

The hip sag and shoulder shake are also crucial for controlling space and managing the partner's movements. Sagging the hips involves sprawling and directing one hip bone down towards the mat more heavily by chambering the opposite leg. This action is beneficial when countering butterfly hooks or when the partner attempts to hip escape. Rolling the shoulder forward while gripping the partner's back creates a clamp with the deltoid and palm, immobilizing the partner more effectively than simply pulling back the elbow.

These techniques are not only pivotal for achieving the folding pass but also for applying cross-faces and other controlling movements. Understanding how to use the body's weight and larger muscle groups will lead to more efficient and powerful transitions and controls.
