How to perform this exercise
  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.

How to perform this exercise
  1. This exercise is best performed inside a squat rack for safety purposes. To begin, first place a flat bench or a box behind you. The flat bench is used to teach you to set your hips back and to hit depth.
  3. Then, set the bar on a rack 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.
  4. 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.
  5. 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 as looking down will get you off balance 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).

Why You Might Need a Barbell Squat (on Knees) Alternative

You might substitute Barbell Squat (on Knees) for pain, limited equipment, or safety concerns. Knee-focused barbell variations can increase patellofemoral stress and spinal load; machines or unilateral moves shift forces and control range of motion. For example, the leg press reduces lumbar compression, whereas Bulgarian split squats let you target the quads with less axial load. When choosing a substitute, cue a neutral spine, active core brace, and knees tracking over toes to maintain quad-dominant torque and reduce compensatory hip-dominant patterns.

How to Choose the Right Substitute

Select a substitute based on your goal, available equipment, and movement tolerances. For hypertrophy choose exercises that allow high time under tension and progressive loading (e.g., front squat or leg press); for joint rehab favor machines or partial range-of-motion work. Prioritize movement patterns that emphasize knee extension: keep torso upright, cue knees to track over toes, and drive through the mid-foot to increase quadriceps activation. Also consider unilateral work to correct imbalances and always adjust volume if you limit ROM or experience pain.

Frequently Asked Questions

What muscles does Barbell Squat (on Knees) work?

Barbell Squat (on Knees) primarily targets the quadriceps via knee extension, with secondary activation of the gluteus maximus and adductors depending on torso angle. Keep your knees tracking over your toes and maintain an upright torso to emphasize vastus lateralis and medialis engagement.

What is the best bodyweight alternative to Barbell Squat (on Knees)?

The single-leg Bulgarian split squat is the top bodyweight substitute because it isolates the quads while reducing spinal load. Cue a slightly forward shin angle, keep your torso tall, and drive through the front mid-foot to maximize knee-extension torque and quadriceps activation.

Can I build muscle without doing Barbell Squat (on Knees)?

Yes — you can build quad mass with front squats, leg presses, hack squats, Bulgarian split squats, or sissy squats by applying progressive overload and sufficient volume. Emphasize technique cues like upright torso and full knee extension to ensure high quadriceps recruitment while avoiding compensatory hip-dominant patterns.
