Step-by-step

  1. Position your feet 12 to 18 inches in front of the bar, shoulder-width apart, and unrack the Smith bar across your upper traps.
  2. Brace your core, keep your chest tall, and begin sitting your hips straight down as if lowering into a chair behind you.
  3. Descend until your thighs are parallel to the floor or as low as control allows, keeping your knees tracking over your toes.
  4. Drive through your full foot to press the floor away, extend your hips and knees together, and re-rack with a deliberate twist of your wrists.

Common mistakes

  • Letting the knees cave inward under load, which stresses the joint and kills power, so actively push your knees out in line with your second toe throughout the rep.
  • Placing the feet directly under the bar as you would a free squat, which forces the shins too vertical and limits depth, so walk your feet forward until the bar sits comfortably behind your center of mass at the bottom.
  • Relying on the Smith machine to hold your torso up by leaning back into the bar, which removes muscle tension and trains poor posture, so maintain active core bracing and treat the bar only as a guide not a crutch.

Pro tip — At the bottom of each rep pause for a full one-second count before driving up, this eliminates momentum and forces your quads to generate force from a dead stop, accelerating strength gains faster than continuous reps.
