Place a loaded barbell on the safety bar of the squat rack and stand upright with your feet shoulder-width apart in front of it.
2. Grab the barbell in an overhand grip with your hands just outside shoulder-width apart.
3. Use your hips, knees and ankles to pull the barbell up to chest height with an explosive movement.
4. Once the bar has reached your chest, quickly bring your elbows underneath the bar.
5. Now you have reached the starting point of a regular barbell shoulder press so just like that exercise, raise the bar vertically by extending your arms over your head and pressing through your palms.
6. Once your arms are fully extended, pause for a moment and lower the bar back on your upper chest and after that, lower the bar back to the starting position.
