How to Perform

  1. Step under the barbell and rest it across your upper trapezius muscles while gripping the bar firmly with both hands.
  2. Unrack the weight by extending your legs and take two small steps back to establish a shoulder-width stance with toes slightly pointed out.
  3. Inhale and brace your core as you lower your hips by bending at the knees and sitting back until your thighs are parallel to the floor.
  4. Keep your chest upright and maintain a neutral spine throughout the descent to ensure proper weight distribution.
  5. Drive through your mid-foot to extend your hips and knees until you return to the initial standing position.
  6. Exhale at the top of the movement and reset your breath before beginning the next repetition.
