The again squat, universally hailed the king of leg workout routines, holds a timeless place within the realm of energy coaching. It’s a primary barbell motion that challenges not solely your bodily energy, however psychological energy as effectively.

The explanation it’s such a tricky train to beat has to do with not simply muscular energy, however muscular coordination, as effectively. (1) While you carry out the basic barbell squat, you’re recruiting a number of muscle teams on the similar time, from head to toe, whereas coordinating your effort amongst the bodily and technical calls for of the train.

Whereas many workout routines can have their place in a leg exercise, in the event you’re in search of to reinforce the muscular density and energy of your decrease physique, the again squat is the undisputed champion. It places your muscle tissues to the check, because it calls for a degree of metabolic dedication that’ll set off a spike in progress hormone that performs a job in stimulating hypertrophy. (2)

Take a better look and concentrate on the mechanics of the squat, the muscle tissues recruited, and a few easy and efficient variations that may make it easier to get essentially the most out of the time-tested again squat.

What Muscle tissues Do Squats Work?

Find out how to Do the Squat— A Method Information

The barbell again squat can seem deceptively easy at first — put the bar in your again, squat down, and arise. Nevertheless, there are numerous particulars to this carry that may usually be neglected, comparable to particular bar placement, hand and foot place, and the posture of your head and neck.

Right here’s a step-by-step information to performing the squat, together with some tricks to turn out to be a greater squatter. Security is essential. Be certain that to use all of those steps for each particular person repetition to not solely get stronger, however to coach smarter, too. 

Step One — Set the Barbell Peak

Set the barbell at shoulder-height in a squat rack. While you grip the bar, place your arms parallel to the bottom, making certain a snug grip width that fits your shoulder mobility. Beginning with a shoulder-width grip is beneficial, however regulate to your particular person stability of mobility and stability.

Coach’s Tip: In the event you encounter difficulties along with your shoulder mobility, carry out an intensive upper-body warm-up earlier than beginning your leg exercise to enhance your shoulder and chest mobility.

Step Two — Place the Bar and Create a Shelf

Select between utilizing both a excessive bar or low bar placement. What deciphers between a excessive bar or low bar place is whether or not the barbell is above your rear deltoids, or on high of (or under) your rear deltoids.

A high-bar squat tends to emphasise the knee joint which might recruit extra quadricep dominance than a low-bar squat, which might place the burden nearer to the hip joint to recruit the glute muscle tissues. Choose the bar placement that aligns along with your coaching targets.

“Constructing a shelf” helps to create an area for the barbell to take a seat comfortably on the higher again to squat. To construct a shelf, retract your scapulae (shoulder blades) and tighten your higher again to create a steady shelf for the bar to relaxation on.

Guarantee your elbows are positioned beneath the bar, additional securing it and selling higher posture. In case your elbows aren’t below the bar or close to perpendicular to the ground, your higher again may lose tightness and trigger your backbone to bend ahead. 

Coach’s Tip: To assist preserve your elbows beneath the bar, discover your grip width on the bar. The broader the grip, the extra mobility your shoulder must help this side of your squatting efficiency.

Step Three — Unrack the Weight and Set Your Stance

Elevate the barbell off the J-hooks and take two steps again. In the event you’ve set your barbell top appropriately, it must be comparatively simple to unrack the burden. When stepping again, preserve the preliminary step small, because the second step is primarily used to regulate your stance. Keep away from stepping too far again, as this may make it tougher to re-rack the burden later.

Your stance considerably influences muscle engagement. For a extra quadriceps-focused squat, go for a better stance along with your toes ahead or barely outward. Athletes ought to preserve their ft ahead to imitate the stance of their particular sport. (3)

In case you are in search of most squat energy, angle your toes barely outward to verify your knees keep outward in a extra advantageous place. If you wish to have interaction your hips extra, stand wider and switch your toes outward — a way usually utilized by powerlifters and strongman opponents. 

Coach’s Tip: The strongest and comparatively greatest muscle tissues of the physique are your glutes. If you wish to maximize energy, you need to use a extra “glute-dominant” variation of the squat. Be certain that your ft are a little bit wider than a standard stance, along with your toes outward. Think about using a low-bar place, as effectively.

Step 4 — Head Place

To take care of a flat and inflexible backbone all through the squat, ensure you place your head barely down at roughly a 45-degree angle. This head placement helps flatten the cervical backbone — the vertebrae of your neck — which helps affect the remainder of your backbone to stay steady through the carry.

Coach’s Tip: In the event you battle to have good posture, begin off along with your head barely going through down, however, as you carry out the squat, preserve your head barely ahead till you hit your sticking level shifting upward. When you hit that sticking level, tilt your head up and ahead to assist affect your backbone to “get taller.” This could put you in a greater place and enhance your squat. 

Step 5 — Time to Squat

After the detailed means of organising in a great place, it’s time to carry out the squat itself.

  • Preliminary Section: Earlier than starting the descent, brace your core by taking a deep breath by your stomach, growing stress inside your belly cavity. This method enhances decrease again rigidity and total posture. Think about using a lifting belt for added help. To maintain the brace in your core, breathe by your nostril, and don’t enable your shoulders to rise throughout your preliminary breath. 
  • Descending Section: As you decrease into the squat, guarantee your hips transfer downward and barely again to distribute the burden evenly throughout your mid-foot. The aim is to keep up correct alignment between your knee and hip joints. Purpose to succeed in a snug depth, along with your thighs close to parallel to the bottom or barely decrease.
  • Ascending Section: Through the ascent, take note of potential “sticking factors” because the load will get heavier. When your energy will get challenged, method turns into essential. The higher your method is from begin to end, the extra probably you’ll be able to battle by that sticking level to finish the carry. Return upright to a full lockout.

By following every of those steps and sustaining correct type all through the motion, you’ll maximize head-to-toe muscle engagement and scale back the possibilities of frequent errors, making certain a profitable and efficient squat.

Muscle Recruitment Throughout Squats

Time to dig deep into the anatomy of the barbell again squat, exploring the first muscle tissues and secondary muscle tissues required to carry out the motion.

The barbell again squat recruits a mix of main and secondary muscle tissues, with the quadriceps and glutes taking the lead in knee and hip extension, respectively. Correct engagement of those muscle teams, and the help of secondary muscle tissues, is essential for executing a protected and efficient squat.

Main Muscle tissues

A main muscle is the primary focused muscle used throughout an supposed motion. The muscle tissues are usually the bigger muscle tissues of the anatomy, particularly throughout a compound motion which includes shifting at a number of joints — within the squat, you’re shifting on the hips, knees, and ankles. The first muscle tissues of the squat are the quadriceps and the glute maximus.

  • The quadriceps are a gaggle of 4 muscle tissues situated on the entrance of the higher leg. 
  • The first operate of the quadriceps is knee extension, which is essential through the ascending section of the squat. They play a pivotal position in straightening the knee joint as you carry the burden.
  • The quadriceps are closely engaged when an athlete depends on their knee joint to maneuver the burden. The knee joint is perhaps prioritized throughout a high-bar squat, a squat to full (under parallel) depth, or when the athlete’s knees start to interrupt far in entrance of their toes. 


  • The gluteus maximus, the most important of the gluteal muscle tissues, types the majority of the hip joint. 
  • The glutes are chargeable for hip extension, which is essential for rising from a squat place. They supply the facility wanted to straighten the hips.
  • The gluteus maximus is closely engaged when an athlete begins to rely extra on their hip joint to drive the burden up. The hip joint is perhaps prioritized when an athlete performs a low-bar squat, field squat, or when the athlete has “vertical shins,” which implies they’re placing extra weight on their heels than their toes. 

Secondary Muscle tissues

A secondary muscle tends to be a comparatively smaller muscle group that aids the first muscle(s) with executing an train. The secondary muscle tissues that present help and stabilization through the squat are the hamstrings, calves, decrease again, and core muscle tissues.

  • The hamstrings are situated in the back of your higher leg, operating out of your hips to you knees.
  • Whereas primarily chargeable for knee flexion (like leg curls), the hamstrings help in hip extension (straightening your higher leg according to your torso). Your hamstrings assist management the descending section of the squat, performing as stabilizers.


  • The calves are comprised of the gastrocnemius and soleus muscle tissues, and are situated behind your decrease leg.
  • The first operate of the calf muscle tissues is the extension of the ankle joint — “pointing” your foot down. Whereas indirectly concerned within the squat, they assist stabilize the ankle joint, particularly when pushing by the mid-foot. If you wish to have an ideal squat, you need to preserve your ft flat throughout every rep, that means you want nice ankle mobility, which depends on versatile calf muscle tissues. 

Erector Spinae (Decrease Again)

  • The erector spinae muscle tissues run alongside your backbone’s size, supporting and stabilizing your decrease again, particularly. 
  • The erector spinae muscle tissues are chargeable for spinal extension, serving to to keep up an upright torso place through the squat.


  • Your core contains muscle tissues such because the rectus abdominis, obliques, and transverse abdominis.
  • Core muscle tissues present stability to the torso, serving to preserve correct posture and stopping extreme spinal flexion or extension. They work along side the erectors, as effectively.

Find out how to Emphasize Key Muscle tissues

As talked about earlier, the first muscle tissues used to squat are the quadriceps and the glutes. Nevertheless, to emphasise one muscle group over the opposite is dependent upon adjusting your setup and motion, together with foot placement, stance, depth, and barbell placement. (4)

Maximizing Quadriceps Recruitment

For these in search of to develop and strengthen their quadriceps, begin by positioning your ft nearer collectively, both at shoulder-width or barely narrower. This narrower stance magnifies the involvement of your quadriceps through the squat, intensifying their engagement.

To additional emphasize quadriceps recruitment, favor a high-bar placement with the barbell in your higher again. Putting the bar increased in your again shifts your heart of gravity ahead, making certain that your quadriceps take the brunt of the load.

This strategic bar placement is a key component in successfully focusing on and strengthening the quadriceps, particularly for these in a hypertrophic (muscle-building) section of coaching. 

One other trick towards quad-dominance goes under a parallel depth. This elevated depth tends to trigger the shins to lean ahead, placing the ankle inside an ideal vary of movement (often known as “dorsiflexion”) which is able to put extra pressure on the knee joint. This causes the quadriceps to be extra activated.

Maximizing Glute Recruitment

In case your goal facilities on maximizing glute engagement, widen your stance past a shoulder-width place and level your toes out. This may affect your shins to remain upright, redirecting the main focus to your glutes and intensifying their involvement.

You must also use a low-bar place to shift the burden distribution at your hip joints. This helps you get a greater hip hinge, which accentuates glute recruitment. Putting the bar decrease in your again ensures that the glutes play a extra dominant position within the squat.

For many who battle with feeling glute recruitment, attempt together with a “pause” within the backside place, and even use a field squat variation, because the field enforces the cue to push your hips backward as a substitute of down. That’s a key level— in case your hips transfer additional again, your glutes might be extra engaged.

Squatting straight down pushes your higher thighs ahead as you descend, inflicting your knees to be extra recruited, which might trigger a extra quadriceps-dominant motion.

Squat Variations

There are a number of different squat variations that can be utilized to additional emphasize recruitment of both your quadriceps or glutes. By making modifications to the bar place or, in some instances, avoiding the usual barbell fully, you’ll be able to pressure your physique to recruit totally different muscle tissues whereas performing the identical elementary squatting motion.

Entrance Squat

On this variation, the barbell is positioned on the entrance of your shoulders moderately than throughout your higher again. To attain this distinctive place, you’ll be able to both cross your arms over one another to carry the barbell or use an Olympic weightlifting-style “rack” place that places your arms parallel to one another along with your arms bent and the bar close to your fingertips.

The defining characteristic of the entrance squat is its demand for a extra upright torso posture. That is what would make the motion extra quadriceps-dominant than glute-dominant, much like a high-bar squat. 

The entrance squat promotes improved posture and spinal alignment. It strengthens your higher again whereas decreasing the chance of forward-leaning tendencies usually related to the basic barbell again squat.

SSB Squat

The SSB (security squat bar) is a specialised barbell that has pads and forward-pointing handles that maintain the burden on high of your shoulders and higher again. The burden distribution creates a forward-leaning higher physique angle in comparison with a regular barbell , which considerably impacts the mechanics of the squat. This makes it a extra quadriceps-dominant variation.

The SSB squat is a perfect alternative for people who could have mobility limitations in sure areas just like the shoulders. Moreover, the SSB squat locations a considerable focus, not solely on the quadriceps, but additionally the higher again and the posterior chain. It delivers an ideal problem to not simply quadriceps energy, however postural energy as effectively. 

By way of muscle engagement, the first goal through the SSB squat is your quadriceps. Nevertheless, the angled handles additionally deliver your higher again and posterior chain into play. This shift in muscle emphasis units it aside from the basic barbell again squat, which primarily targets the quadriceps however doesn’t have interaction the higher again and posterior chain to the identical extent.

Belt Squat

The belt squat is in contrast to the entrance squat or SSB squat. As a substitute of inserting a barbell in your higher physique, you put on a belt round your waist connected both to a specifically designed platform or to a barbell on the bottom set in a landmine unit. The belt distributes weight throughout your hips, which makes it a glute-dominant variation of the barbell squat.

The belt squat affords an efficient technique of difficult the decrease physique with out inserting weight in your torso and backbone, making it significantly appropriate for people coping with again points.

Moreover, the belt squat targets your legs with little to no higher physique involvement. This may be an ideal train for these with particular limitations, together with poor shoulder mobility, spinal compression points, or an incapability to carry a barbell with one or each arms.

Time to Squat

The barbell again squat is a high train that engages a number of muscle teams and delivers huge advantages, from growing energy and energy to constructing extra muscular legs. Total muscle recruitment throughout squats is a vital variable that may be manipulated by your stance, motion, and bar place. Regardless of the way you do it, the squat is an iconic carry that may enhance anybody’s success in constructing measurement, energy, and athleticism.
