Squat (Smith Machine)

The Smith machine squat is a lower body exercise performed on a fixed vertical or near-vertical bar path, targeting the quadriceps and glutes. It suits lifters who want additional stability during squats or need to train around balance limitations.

How to do the Squat (Smith Machine)

  1. Set the bar at upper chest height and position yourself under it so the bar rests on your upper traps, feet shoulder-width apart and slightly forward of the bar.
  2. Unrack the bar by standing up and rotating the hooks out of the catches.
  3. Inhale and descend by bending at the hips and knees simultaneously, keeping your chest up and core braced.
  4. Lower until your thighs are at least parallel to the floor or as deep as your mobility allows while maintaining a neutral spine.
  5. Drive through your midfoot and heels to stand back up, exhaling as you reach the top.
  6. Rotate the bar back into the catches when finished with your set.

Form tips

  • Keep your feet positioned far enough forward that your knees stay behind or at your toes at the bottom to maintain proper shin angle.
  • Maintain three points of contact with the bar on your upper back throughout the movement to prevent the bar from rolling or shifting.
  • Push your knees outward in line with your toes during the descent and ascent to engage the glutes and prevent knee valgus.

Common mistakes

  • Placing feet directly under the bar like a free weight squat: this forces an unnatural forward knee travel due to the fixed bar path.
  • Rising with the hips first while the chest stays down: this shifts the load forward and reduces quadriceps engagement.
  • Bouncing out of the bottom position: this relies on momentum rather than muscular control and increases joint stress.

Sets and reps

For strength, perform 3 to 5 sets of 3 to 6 reps with heavier loads; for hypertrophy, use 3 to 4 sets of 8 to 12 reps with moderate weight.

Frequently asked questions

Should my feet be positioned differently on a Smith machine squat compared to a barbell squat?
Yes, your feet should be positioned several inches forward of the bar on a Smith machine to accommodate the fixed vertical path. This allows you to sit back into the squat without the bar path forcing your knees excessively forward.
Is the Smith machine squat easier than a barbell squat?
The Smith machine squat removes the need to balance the bar, which can allow you to lift heavier loads or focus purely on leg drive. However, it does not train stabilizer muscles to the same degree as free weight squats due to the fixed bar path.
Where should the bar sit on my back during a Smith machine squat?
The bar should rest on your upper trapezius muscles in a high bar position, similar to a traditional back squat. Avoid placing it on your neck or too low on your rear deltoids, as the fixed path works best with a more upright torso angle.
