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.
