    • Quads
    • Smith-machine
    • Intermediate
    • Compound
    How to perform this exercise
    1. To begin, place a flat bench 2-3 feet behind the smith machine. Then, set the bar on the height that best matches your height. Once the correct height is chosen and the bar is loaded, step under the bar and place the back of your shoulders (slightly below the neck) across it.
    2. Hold on to the bar using both arms at each side (palms facing forward), unlock it and lift it off the rack by first pushing with your legs and at the same time straightening your torso.
    3. Position your legs by placing one foot slightly forward under the bar and extending your other leg back and place the top of your foot on the bench. This will be your starting position
    4. Begin to slowly lower the bar by bending the knee as you maintain a straight posture with the head up. Continue down until the angle between the upper leg and the calf becomes slightly less than 90-degrees (which is the point in which the upper legs are below parallel to the floor). Inhale as you perform this portion of the movement. Tip: If you performed the exercise correctly, the front of the knee should make an imaginary straight line with the toes that is perpendicular to the front. If your knee is past that imaginary line (if it is past your toes) then you are placing undue stress on the knee and the exercise has been performed incorrectly.
    5. Begin to raise the bar as you exhale by pushing the floor with the heel of your foot mainly as you straighten your leg again and go back to the starting position.
    6. Repeat for the recommended amount of repetitions.
    7. Switch legs and repeat the movement.

    Sets and reps: 3 or 4 sets of 6 to 10 reps on each side.

    Why this matches
    • Primary muscle: quads, the same as the Barbell One Leg Squat
    • Equipment: a machine, not free weights

    3. Move one foot forward about 12 inches in front of the bar. Extend the other leg out in front of you, holding it off the ground. Look forward at all times and maintain a neutral or slightly arched spine. This will be your starting position.
    4. Maintaining good posture, lower yourself by flexing the knee and hip, going down as far as flexibility allows.
    5. Pause briefly at the bottom and then return to the starting position by driving through the heel of your foot, extending the knee and hip.

Why You Might Need a Barbell One Leg Squat Alternative

You may substitute the Barbell One Leg Squat because of limited ankle or hip mobility, knee pain, balance deficits, or lack of a stable rack. Single-leg barbell work demands high knee-extension torque and strong hip stabilizers; if you feel excessive valgus or pain, pick a less technical option. For rehab or load progression, reduce range with a box-assisted Bulgarian split squat (set back foot on a low box) and keep weight over the mid-foot to limit shear forces. If you lack a barbell, choose goblet variations to preserve quad activation while reducing spinal loading.

Barbell One Leg Squat FAQ

What muscles does Barbell One Leg Squat work?

The exercise primarily targets the quadriceps through knee extension torque and also recruits the gluteus maximus and hamstrings for hip stability. Deep core and hip-abductor muscles engage to control frontal- and transverse-plane motion during the single-leg stance.

What is the best bodyweight alternative to Barbell One Leg Squat?

A goblet pistol squat is the best bodyweight-focused option because it preserves a similar single-leg knee-extension pattern while lowering spinal load. Cue a tall chest, sit-back to a box if needed, and drive through the heel-to-mid-foot to emphasize quads and maintain balance.
