To perform an overhead squat with a clean grip, start by standing with your feet shoulder-width apart and holding the barbell overhead with a shoulder-width grip, as used in the clean. Keep your arms fully extended and your core engaged. Squat down by bending at the hips and knees, maintaining a straight back and keeping the barbell stable overhead. Lower until your thighs are parallel to the ground or lower, then push through your heels to return to the starting position. Focus on balance, stability, and controlled movement throughout the exercise.
