Feet positioned in an athletic stance just inside shoulder-width. Your knees are slightly bent and toes pointed straight ahead.
The core and glutes are braced and engaged with a neutral spine.
Your back is never arched.
Grip a barbell with a pronated grip inside shoulder-width.
Press the barbell overhead, your arms are fully extended and elbows in.
Imagine bringing your armpits forward. This will create a stable shoulder position.
Don't let your wrist roll back.
Begin by lowering the bar behind your head in a semicircular movement keeping your elbows relatively fixed.
Feel your triceps eccentrically loading.
Elbow do not flare excessively internally or externally.
Initiate the mind-muscle connection of creating and maintaining tension in the tricep throughout the exercise.
Your elbows can track behind you slightly.
Extend your arms to bring the bar back to the starting position.
Bar follows the same semicircular path as the eccentric.
*Tips*
Keep the weight light and aim for volume. Heavy weight can wreak havoc on your elbows if you perform the exercise incorrectly or attempt to progress too fast.
Don't let your back arch/overextend. Keep your core braced and glutes activated to prevent this.
