Section 4.2: The Push Press

The push press is the second movement in the CrossFit overhead press series. It builds directly upon the mechanics of the shoulder press but introduces a dynamic leg drive to assist in moving the load overhead. By utilizing the larger, more powerful muscle groups of the lower body (quadriceps, glutes, and hamstrings), the push press allows an athlete to lift approximately 30% more weight than is possible with a strict shoulder press. For the CrossFit Level 1 Trainer, the push press is a primary tool for teaching the core-to-extremity principle, demonstrating how power generated in the hips can be transferred through a rigid midline to the upper extremities.

Setup: The Active Rack

The setup for the push press is nearly identical to that of the shoulder press, with one minor adjustment to the arm position to accommodate the dynamic nature of the movement.

• Stance: The athlete assumes a hip-width stance. The feet are positioned directly beneath the hips, with the weight balanced on the heels.
• Grip: The hands are placed slightly wider than shoulder-width with a closed, hook-less grip, thumbs wrapped around the bar.
• Elbow and Rack Position: The barbell rests on the anterior deltoids and clavicles. However, the elbows are positioned slightly lower (closer to the body) than they would be in a front squat or clean rack, but still slightly in front of the bar. This compromise allows the barbell to remain supported by the torso during the dip, while keeping the hands and forearms in an advantageous position to press the bar once the leg drive is complete.
• Midline Setup: The core is aggressively braced, the glutes are tight, and the pelvis is held in a neutral position. The spine must remain neutral throughout the entire lift.

Execution: The Dip-Drive-Press Sequence

The execution of the push press is defined by three distinct, continuous phases: the dip, the drive, and the press.

1. The Dip (The Deceleration Phase)

The dip is the descent that stores elastic energy in the lower body.

• Vertical Torso: The athlete bends at the knees and hips, descending straight down. The torso must remain perfectly vertical. If the chest leans forward or the hips slide backward, the power of the leg drive will be directed forward rather than vertically, causing the bar to travel away from the athlete.
• Heels Down: The weight must remain firmly on the heels. Lifting the heels during the dip shifts the load to the quadriceps and knees, reduces stability, and disrupts the vertical drive.
• Shallow Depth: The dip is a shallow, rapid movement, descending only 2 to 3 inches (approximately 1/5 of a squat). A dip that is too deep loses speed and transitions into a squat, which diminishes the elastic rebound effect.

2. The Drive (The Acceleration Phase)

The drive is the explosive reversal of the dip.

• Explosive Extension: The athlete aggressively extends the hips and knees, driving through the heels. This must be an explosive, violent contraction.
• Transfer of Momentum: As the hips and knees lock out, the upward momentum is transferred through the rigid spine to the barbell. The bar will actually fly off the shoulders.
• Heels Grounded: The heels must remain in contact with the ground until the hips and knees are fully extended to ensure maximum force transfer.

3. The Press (The Finish Phase)

The press is the upper-body finish that guides the bar to lockout.

• Late Pressing: The arms do not begin to press the bar until the hips and knees have reached full extension. The legs do the majority of the work; the arms simply finish the lift.
• Lockout: The athlete presses the bar to a fully locked-out position overhead. The head is pushed through the window of the arms, the elbows are locked, and the shoulders are active (shrugged). The hips and knees remain fully extended.

The Core-to-Extremity Principle

The push press is a textbook application of CrossFit’s core-to-extremity rule. In human movement, force is maximized when it is initiated by the large, high-power muscle groups of the core and pelvis (the hips and thighs) and then transferred to the smaller, lower-power muscle groups of the extremities (the shoulders and arms). Attempting to press the bar before the hips have finished extending violates this principle, overloading the shoulders and reducing the total weight that can be lifted.

Common Faults and Corrections

Coaches must identify and correct three primary faults to preserve the efficiency and safety of the push press:

• Mute Hip: Characterized by hips remaining flexed or pushing forward during the drive, rather than extending explosively. This is corrected by cueing the athlete to squeeze their glutes and stand up fast.
• Leaning Forward (Chest Drops): Characterized by the chest pitching forward and hips sliding back during the dip. This is corrected by cueing the athlete to keep their chest up and dip straight down, as if sliding down a wall.
• Early Press: Characterized by the arms beginning to press the bar before the hips and knees are fully extended. This is corrected by cueing the athlete: "Legs, then arms!"
• Pause in the Dip: Characterized by the athlete stopping at the bottom of the dip, losing the stretch-shortening cycle. This is corrected by cueing a fast transition: "Down, up!" or "Bounce!"

Level 1 Progression for the Push Press

To teach the push press, coaches should guide athletes through these steps:

1. Dip and Hold: Focus on heels down, vertical torso, and shallow 2-3 inch depth.
2. Dip-Drive (Slow): Dip, then stand up slowly to establish control.
3. Dip-Drive (Fast): Dip and drive explosively, keeping arms relaxed and letting the bar float off the shoulders.
4. Push Press: Add the upper-body press, ensuring the press only begins after full hip extension.

Biomechanical Mechanics of the Dip-Drive

The dip and drive phases rely on the stretch-shortening cycle (SSC), which is a key concept in explosive training. During the rapid dip, the quadriceps and gluteal muscles undergo an eccentric contraction, stretching the muscle fibers and storing elastic energy. The rapid transition from the dip to the drive (the amortization phase) must be virtually instantaneous. If the athlete pauses at the bottom of the dip, this stored energy is dissipated as heat, and the mechanical advantage is lost. The subsequent drive then relies purely on concentric force, which is significantly less powerful.
