How to Perform Lying Machine Squat

1. Adjust the leg machine to a height that will allow you to get inside it with your knees bent and the thighs slightly below parallel.
2. Once you select the weight, position yourself inside the machine face up with the knees bent and thighs slightly below parallel to the platform. Make sure that the knees do not go past the toes. The angle created between the hamstrings and the calves should be one that is slightly less than 90 degrees (since your starting position requires you to start slightly below parallel). Your back and your head should be resting on the machine while your shoulders are pressed under the shoulder pads.
3. Place your hands by the handles and position your feet slightly pointing out at a shoulder width position. This will be your starting position.
4. While pressing with the balls of the feet as you breathe out, make your whole body erect as you squeeze the quads. Hold the contracted position for a second. Tip: Since you are starting below parallel, you can opt to use your hands to help you up by pressing on your thighs only on the first repetition.
5. Slowly squat down as you inhale but instead of going all the way down to the starting position, just stop once your thighs are parallel to the platform. The angle between your hamstrings and calves should be a 90-degree angle.
6. Repeat for the recommended amount of repetitions.

1. Calf Press

78.7% Match

Calves Machine Beginner Isolation

How to perform this exercise

1. Adjust the seat so that your legs are only slightly bent in the start position. The balls of your feet should be firmly on the platform.
2. Select an appropriate weight, and grasp the handles. This will be your starting position.
3. Straighten the legs by extending the knees, just barely lifting the weight from the stack. Your ankle should be fully flexed, toes pointing up. Execute the movement by pressing downward through the balls of your feet as far as possible.
4. After a brief pause, reverse the motion and repeat.

2. Calf Press On The Leg Press Machine

78.7% Match

Calves Machine Beginner Isolation

How to perform this exercise

1. Using a leg press machine, sit down on the machine and place your legs on the platform directly in front of you at a medium (shoulder width) foot stance.
2. Lower the safety bars holding the weighted platform in place and press the platform all the way up until your legs are fully extended in front of you without locking your knees. (Note: In some leg press units you can leave the safety bars on for increased safety. If your leg press unit allows for this, then this is the preferred method of performing the exercise.) Your torso and the legs should make perfect 90-degree angle. Now carefully place your toes and balls of your feet on the lower portion of the platform with the heels extending off. Toes should be facing forward, outwards or inwards as described at the beginning of the chapter. This will be your starting position.
3. Press on the platform by raising your heels as you breathe out by extending your ankles as high as possible and flexing your calf. Ensure that the knee is kept stationary at all times. There should be no bending at any time. Hold the contracted position by a second before you start to go back down.
4. Go back slowly to the starting position as you breathe in by lowering your heels as you bend the ankles until calves are stretched.
5. Repeat for the recommended amount of repetitions.

3. Dumbbell Squat To A Bench

74% Match

Quadriceps Dumbbell Beginner Isolation

How to perform this exercise

1. Stand up straight with a flat bench behind you while holding a dumbbell on each hand (palms facing the side of your legs).
2. 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.
3. Begin to slowly lower your torso by bending the knees as you maintain a straight posture with the head up. Continue down until you slightly touch the bench behind you. 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.
4. Begin to raise the bar as you exhale by pushing the floor with the heel of your foot mainly as you straighten the legs again and go back to the starting position.
5. Repeat for the recommended amount of repetitions.

4. Chair Squat

72.4% Match

Quads Machine Beginner Isolation

How to perform this exercise

1. To begin, first set the bar to a position that best matches your height. Once the bar is loaded, step under it and position it across the back of your shoulders.
2. Take the bar with your hands facing forward, unlock it and lift it off the rack by extending your legs.
3. Move your feet forward about 18 inches in front of the bar. Position your legs using a shoulder width stance with the toes slightly pointed out. Look forward at all times and maintain a neutral or slightly arched spine. This will be your starting position.
4. Slowly lower the bar by bending the knees as you maintain a straight posture with the head up. Continue down until the angle between the upper and lower leg breaks 90 degrees.
5. Begin to raise the bar as you exhale by pushing the floor with the heels of your feet, extending the knees and returning to the starting position.

5. Box Squat

69.4% Match

Quadriceps Barbell Intermediate Isolation

How to perform this exercise

1. The box squat allows you to squat to desired depth and develop explosive strength in the squat movement. Begin in a power rack with a box at the appropriate height behind you. Typically, you would aim for a box height that brings you to a parallel squat, but you can train higher or lower if desired.
2. Begin by stepping under the bar and placing it across the back of the shoulders. Squeeze your shoulder blades together and rotate your elbows forward, attempting to bend the bar across your shoulders. Remove the bar from the rack, creating a tight arch in your lower back, and step back into position. Place your feet wider for more emphasis on the back, glutes, adductors, and hamstrings, or closer together for more quad development. Keep your head facing forward.
3. With your back, shoulders, and core tight, push your knees and butt out and you begin your descent. Sit back with your hips until you are seated on the box. Ideally, your shins should be perpendicular to the ground. Pause when you reach the box, and relax the hip flexors. Never bounce off of a box.
4. Keeping the weight on your heels and pushing your feet and knees out, drive upward off of the box as you lead the movement with your head. Continue upward, maintaining tightness head to toe.

6. Box Squat With Chains

68.7% Match

Quadriceps Barbell Intermediate Isolation

How to perform this exercise

1. Begin in a power rack with a box at the appropriate height behind you. Typically, you would aim for a box height that brings you to a parallel squat, but you can train higher or lower if desired.
2. To set up the chains, begin by looping the leader chain over the sleeves of the bar. The heavy chain should be attached using a snap hook. Adjust the length of the lead chain so that a few links are still on the floor at the top of the movement.
3. Begin by stepping under the bar and placing it across the back of the shoulders. Squeeze your shoulder blades together and rotate your elbows forward, attempting to bend the bar across your shoulders. Remove the bar from the rack, creating a tight arch in your lower back, and step back into position. Place your feet wider for more emphasis on the back, glutes, adductors, and hamstrings, or closer together for more quad development. Keep your head facing forward.
4. With your back, shoulders, and core tight, push your knees and butt out and you begin your descent. Sit back with your hips until you are seated on the box. Ideally, your shins should be perpendicular to the ground. Pause when you reach the box, and relax the hip flexors. Never bounce off of a box.
5. Keeping the weight on your heels and pushing your feet and knees out, drive upward off of the box as you lead the movement with your head. Continue upward, maintaining tightness head to toe.

7. Box Squat With Bands

68.1% Match

Quadriceps Barbell Intermediate Isolation

How to perform this exercise

1. Begin in a power rack with a box at the appropriate height behind you. Set up the bands on the sleeves, secured to either band pegs, the rack, or dumbbells so that there is appropriate tension. If dumbbells are used, secure them so that they don't move. Also, ensure that the dumbbells you are using are heavy enough for the bands that you are using. Additional plates can be used to hold the dumbbells down. If more tension is needed, you can either widen the base on the floor or choke the bands. Typically, you would aim for a box height that brings you to a parallel squat, but you can train higher or lower if desired.
2. Begin by stepping under the bar and placing it across the back of the shoulders. Squeeze your shoulder blades together and rotate your elbows forward, attempting to bend the bar across your shoulders. Remove the bar from the rack, creating a tight arch in your lower back, and step back into position. Place your feet wider for more emphasis on the back, glutes, adductors, and hamstrings, or closer together for more quad development. Keep your head facing forward.
3. With your back, shoulders, and core tight, push your knees and butt out and you begin your descent. Sit back with your hips until you are seated on the box. Ideally, your shins should be perpendicular to the ground. Pause when you reach the box, and relax the hip flexors. Never bounce off of a box.
4. Keeping the weight on your heels and pushing your feet and knees out, drive upward off of the box as you lead the movement with your head. Continue upward, maintaining tightness head to toe. Use care to return the barbell to the rack.

Why You Might Need a Lying Machine Squat Alternative

You may swap the Lying Machine Squat due to joint pain, unavailable equipment, or specific training goals. Knee or low-back issues often require less spine-compressive or more unilateral options; for example, choose a leg press to reduce lumbar load and keep knees tracking over toes to maintain quad torque. Preference for unilateral strength or balance makes Bulgarian split squats useful because they increase knee flexion and single-leg quad activation. Facility limits or travel may force bodyweight or kettlebell substitutes; use a goblet squat with a raised heel to increase knee moment arm and quad recruitment. Adjust range of motion and stance width to manage patellofemoral stress and target specific quadriceps heads.

How to Choose the Right Substitute

Select a substitute based on joint tolerance, available load, and desired muscle emphasis. If you need heavy, low-back-friendly loading, pick the horizontal leg press and cue pushing through the mid-foot to emphasize knee extension torque. For unilateral strength and balance, choose Bulgarian split squats and keep the torso upright with the front knee tracking over the foot to increase quad strain. If you lack load but want hypertrophy, use slow eccentrics and pause reps on goblet squats to raise time under tension. Consider ankle mobility and adjust stance or use an elevated heel to preserve knee travel while minimizing compensatory hip flexion.
