Study Notes

Introduction to the Jerk

The jerk is the final phase of the clean and jerk, lifting the barbell from the shoulders to overhead.
The actions are similar to the snatch and clean, with the interaction between the lifter and barbell being key.
Force is initially generated against the platform by the lower body to elevate the barbell.
The lifter then moves under the barbell to establish the overhead receiving position.
Learning the jerk involves a collection of specific positions and movements, though the underlying principles are similar to other lifts.
An empty or light technique barbell is used for practice drills, as a PVC pipe or dowel will not allow proper rack position establishment.

The Receiving Position for the Jerk

The receiving position is essential for efficiently and safely lifting heavy weights.
Common jerk styles include the Power Jerk, Squat Jerk, and Split Jerk.
The split jerk is a popular competitive style, while the power jerk is commonly used in training.
The squat jerk is less common but progressively gaining popularity in lighter weight classes.

Types of Jerks and Their Receiving Positions

Power Jerk (Push Jerk): The barbell is received with the feet in a squat-width stance, thighs above parallel.
- Easier to learn, with simpler foot movements.
- Challenges include bar elevation and stability, necessitating precise bar path.

Progression Overview

Grip Placement: The optimal grip width balances stability, pressing strength, and bar path efficiency. Typically similar to clean grip width, around half a fist width outside the shoulders.
Overhead Position: Mirrors the snatch position, but with a narrower grip, shoulder blades retracted and rotated upward, bar path directly above the base of the neck.
Split Position: This stance maximizes balance and bar stability, determined by stances (leading foot position, width, rear foot position) and tested by walking lunges or similar.
Jump to Split: This exercise develops precision, speed, and posture without added complexity of a barbell, building fundamental footwork and positioning.
Important to avoid common mistakes, like uneven foot contact and torso lean to achieve optimal stability and control.

Learning the Jerk

The progression builds from basic movements using light barbells and incorporates complex elements gradually.
Jerk Rack Position: The barbell is directly connected to the trunk for efficient force transfer to the legs during upward movement. Critical elements involve shoulder posture, grip, elbows (should be lowered and spread outward), and arm position.
Stance & Dip: The stance mirrors the snatch and clean, feet slightly wider than hip-width, toes turned out. The dip involves only knee flexion, no hip hinge.
Press: Develops upper body mechanics required to push the bar overhead, ensuring the bar path is correct.
Push Press: Combines the press with a leg drive dip and drive, strengthening overhead strength, good form and maintaining correct mechanics.
Tall Power Jerk: Isolates the action of pushing under the bar after a leg drive. Action involves a punch under the bar and synchronised movement with feet hitting the floor.
Split Jerk Behind the Neck: A variation that simplifies the bar path by starting with the bar behind the neck.
Jerk Balance: This helps with footwork and bar path control to minimize forward leaning.
Split Jerk: This is the final step, integrating all previously learned elements to optimize a complete form, and maximize balance and control.

Safe Jerk Misses

Forward Miss: Front leg steps back and pushes the bar forward.
Backward Miss: The bar is guided backward while moving the body forward.

Squat Jerk (Advanced Style)

This a rarer style involving a full squat with a narrow grip, utilizing extreme mobility and strength due to reduced bar elevation.
It reduces the bar required elevation, suitable for lifters with exceptional mobility and squat strength.

Understanding the Jerk

The jerk is a demanding lift combining explosive power and technical precision, mirroring elements of the snatch and clean, incorporating a dip, a driving, and a push.
Starting Position: Drive stance and rack position, focusing on balance, trunk stability, and proper foot alignment (feet slightly outward).
Rack position is key, connecting the barbell securely to the trunk and not the arms, allowing for fast elbow lockout.
Grip width, thumb position, and trunk pressurization are critical too

The Dip, Drive & Push-Under

Dip: A controlled descent using knees, loading the legs for elastic tension for the drive.
Drive: Explosive leg drive to accelerate barbell upward. The bar path should ideally be vertical or slightly backward.
Push-Under: Moving the body downward while locking out the arms overhead, similar to the third pull in snatch or clean. Receiving position is crucial to maintain stability overhead.

Bar Path Analysis

Successful jerk lifts generally involve a vertical or slightly backward bar path, with minimal horizontal movement.
The bar should be positioned over the lifter's neck with the upper body fully locked. Correct barpath helps with stability and minimizing forward/backward leaning and movement.
