Hold a barbell with both hands shoulder-width apart, palms facing towards your feet, and extend your arms straight above your chest.
Slowly lower the barbell towards your forehead by bending your elbows, keeping your upper arms stationary and perpendicular to the ground.
Pause for a moment when the barbell is just an inch or so above your forehead, ensuring you're controlling the weight and not letting it crash down.
Push the barbell back to the starting position by extending your elbows, contracting your triceps at the top of the lift, and repeating the process for your desired number of repetitions.
Pro Tip
Controlled Movement: As you lower the barbell, do it slowly and in a controlled manner. Your forearms should be the only parts moving. Keep your elbows tucked in and your upper arms stationary throughout the exercise. The barbell should be lowered to the forehead or just above the forehead, hence the name "skull crusher". Avoid the common mistake of moving your elbows or shoulders, as this can lead to injury and reduces the effectiveness of the workout on your triceps. Mind Your Elbows: A common mistake is to flare the elbows out to the sides. This not only reduces the effectiveness of the exercise
