Back Mount Position Fundamentals
Establishing back mount requires first securing a modified mount position and using fundamental body mechanics to control the opponent. When the opponent attempts a knee-elbow escape, the instructor drives forward with his core, causing the opponent's knee to extend outward. This creates the opening needed to drop the attacking leg and establish the first hook for back control.
Solidifying Back Mount Control
Rather than remaining high on the opponent's back, the attacker lifts his feet underneath him and shifts weight onto his own base. By taking small steps backward while maintaining foot positioning, the attacker sinks his hips behind the opponent's hips, creating a much more structurally sound back mount position.
Defending Against the Choke Response
When the attacker begins digging at the collar for a choke, the opponent typically responds by dropping a shoulder to the ground to create a wall. This defensive movement creates a structural weakness in the opponent's turtle position, particularly in the gap between the calf and hamstring on the side where the shoulder drops.
Entry into the Compression Lock Position
The attacker drives his leg through the gap created by the opponent's shoulder drop, positioning his shin against the opponent's calf while maintaining control with the hooks. After stepping over the opponent's calf with his shin, the attacker transitions by dragging his upper body around and dropping his hips to the ground, reaching a modified reverse mount-like position with arms extended over the opponent's back.
Rolling to Isolate the Leg
To generate isolation on the trapped leg, the attacker identifies the opponent's weak base direction at approximately a seven o'clock angle and rolls in that direction. The attacker uses his back leg to push off the ground, rising to his knee, then executes a front roll over his shoulder while maintaining control of the opponent's calf, ensuring the opponent cannot use a base with that leg.
Final Positioning and Compression Setup
After completing the roll, the attacker traps the opponent's shin with his hand, creating strong isolation on the limb. If the opponent's hips settle on the attacker's chest, the attacker uses his laces to lift the opponent's weight momentarily, then slides his chest out to the side, repositioning for the compression lock application.

What are the key details for finishing compression lock?
To generate isolation on the trapped leg, the attacker identifies the opponent's weak base direction at approximately a seven o'clock angle and rolls in that direction. The attacker uses his back leg to push off the ground, rising to his knee, then executes a front roll over his shoulder while maintaining control of the opponent's calf, ensuring the opponent cannot use a base with that leg.
