Set safety pins so thighs are parallel in the squat position. Load barbell and position it on the pins. Stand under the bar, upper back positioned, feet shoulder-width apart. Engage core, grip firmly. Drive through heels to lift, extending hips and knees. Pause at top, lower with control. Reset and repeat.
Maintain a strong core for stability. Lower the bar with a controlled tempo. Start with lighter weight to master form. Plant feet firmly and drive through heels. Keep chest up, shoulders back. Inhale before lifting, exhale on completion.
