NAC Trainer, Ryan Miller shows us:

Barbell Front Squat-
  1.  Stand tall in a shoulder-width stance with feet pointed out. Rest barbell on top of chest. Use an overhand grip to securely hold bar with fingers. Triceps will remain parallel to floor in order to support the weight of the bar.
  2. Inhale and slowly descend hips until thighs become parallel to floor, keeping weight stationary. Pause at the bottom of the squat and then quickly drive hips back to starting position.
