How to perform Barbell Squat
  1. This exercise is best performed inside a squat rack for safety purposes. To begin, first set the bar on a rack to just below shoulder level. 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 and lift it off the rack by first pushing with your legs and at the same time straightening your torso.
  3. Step away from the rack and position your legs using a shoulder width medium stance with the toes slightly pointed out. Keep your head up at all times and also maintain a straight back. This will be your starting position. (Note: For the purposes of this discussion we will use the medium stance described above which targets overall development; however you can choose any of the three stances discussed in the foot stances section).
  4. Begin to slowly lower the bar by bending the knees and hips as you maintain a straight posture with the head up. Continue down until the angle between the upper leg and the calves becomes slightly less than 90-degrees. Inhale as you perform this portion of the movement. Tip: If you performed the exercise correctly, the front of the knees should make an imaginary straight line with the toes that is perpendicular to the front. If your knees are past that imaginary line (if they are 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 as you straighten the legs again and go back to the starting position.
  6. Repeat for the recommended amount of repetitions.

Why You Might Need a Barbell Squat Alternative

You may need to substitute the Barbell Squat for practical or medical reasons. Common causes include lack of a squat rack or heavy barbell, acute or chronic low-back pain that makes loaded spinal extension unsafe, limited ankle or thoracic mobility that prevents a safe bar-path, or knee irritation requiring altered mechanics. Training priorities also drive choices: single-leg variants correct asymmetries and increase unilateral quad activation, while machines permit heavy loading with reduced spinal demand. Technical learning curve and safety concerns often favor goblet or machine options that preserve knee-extension patterns and allow progressive overload without risky technique breakdown.

Barbell Squat FAQ

What muscles does Barbell Squat work?

The Barbell Squat is a compound lower-body lift that primarily targets the quadriceps through knee extension and the glutes and hamstrings through hip extension. It also engages the adductors, spinal erectors, and core as stabilizers during loaded descent and ascent.

What is the best bodyweight alternative to Barbell Squat?

For most lifters the Bulgarian split squat is the best bodyweight alternative: it preserves knee-dominant extension, increases unilateral quad activation, and demands less spinal loading. Progress it by adding tempo, reps, or elevation before moving to weighted variations.
