Squats are one of the most popular exercises in the fitness world. Not only do squats help you build a strong lower body, but they also work several muscles in your body. When done correctly, squats can target your glutes, quadriceps, hamstrings, calves, and even your core.

It’s no wonder why squats are often referred to as the king of exercises. They’re a compound movement, which means they involve multiple joints and muscles groups in the movement. This makes them highly effective for building strength, improving balance, and increasing muscle size and tone.

In this article, we’ll take a closer look at the muscles involved in squats and how you can get the most out of this exercise to achieve your fitness goals. Whether you’re a beginner or an experienced lifter, understanding the muscles worked in squats can help you optimize your workouts and build a stronger, fitter body.

The Benefits of Squats

Increased Muscle Mass

Squats target multiple muscle groups in the lower body, including the quads, hamstrings, glutes, and calves. By engaging these muscles, squats can lead to increased muscle mass and strength in the legs and hips.

Better Balance and Stability

Squats are a functional exercise that mimic movements we do in our daily lives, such as getting up from a chair or squatting down to lift something off the ground. By improving your squat form and building strength in your lower body, you can improve your balance and stability in everyday activities.

Improved Athletic Performance

Squats can help improve your athletic performance in sports that require strong lower body movements, such as sprinting, jumping, and lifting. By targeting the muscles used in these activities, squats can increase power and explosiveness, helping you perform at your best.

Decreased Risk of Injury

By strengthening the muscles in your lower body, squats can help decrease your risk of injury to your knees, hips, and lower back. Improved balance and stability can also help prevent falls and other accidents.

Increased Metabolism and Fat Loss

Squats are a compound exercise that work multiple muscle groups at once, making them a great calorie-burning exercise. By building muscle mass and increasing metabolism, squats can help you burn fat and lose weight.

  • Tip: To maximize the benefits of squats, be sure to use proper form and start with a weight that is comfortable for you. Gradually increase the weight as you build strength and confidence.

The Primary Muscles Worked in Squats


The main muscles targeted during squats are the quadriceps, or the muscles located in the front of the thighs. These muscles comprise four smaller muscles: the rectus femoris, vastus medialis, vastus intermedius, and vastus lateralis. The quadriceps are responsible for extending the knee joint and playing an important role in standing up from a sitting position – an action that is similar to the motion of squats.


The glutes, or the muscles located in your buttocks, are also activated during squats. Specifically, the gluteus maximus is the primary muscle utilized when performing this exercise. The glutes play an important role in extending the hips and supporting the body during the upward phase of a squat.


In addition to the quadriceps and glutes, the hamstrings are also engaged during squats. These muscles are located in the back of the thighs and play a supporting role. Specifically, the hamstrings help to stabilize the knee joint while also assisting in balancing the body throughout the exercise.

  • The gastrocnemius and soleus muscles in the calves are also utilized during squats, helping to stabilize the ankle joint and provide support to the entire body.
  • Other secondary muscles worked during squats include the erector spinae, which support the spine, and the abdominals, which play a key role in maintaining posture and balance.

All in all, squats are a highly effective compound exercise that target multiple muscle groups at once, making them an incredibly efficient way to build strength and muscle mass throughout the lower body.

The Secondary Muscles Worked in Squats

1. Glutes

While the primary muscle worked in squats is the quadriceps, the glutes are also significantly engaged. As you lower yourself down into a squat, your gluteus maximus, medius, and minimus are activated. During the ascent, these muscles help to propel you upwards, which is why many people consider squats to be a great exercise for building a more toned butt.

2. Hamstrings

The hamstrings, located on the back of your thighs, also play an important role in the squatting movement. Specifically, the semitendinosus, semimembranosus, and biceps femoris muscles are activated during the lowering phase of the squat, and then contribute to the pushing phase as you rise back up. Strong hamstrings are important not only for aesthetics, but also for preventing injuries to the knees and lower back.

3. Calves

Although the calves are not as heavily involved in squats as the quads, hamstrings, and glutes, they still play a role in the movement. The gastrocnemius and soleus muscles, located in the back of the lower leg, are activated as you push yourself up from the lowest point of the squat. This can help to strengthen and tone the calf muscles, which can be beneficial for athletes who rely on explosive movements such as sprinting or jumping.

4. Lower Back

Finally, the muscles of the lower back can also be considered secondary movers in the squat. As you lower yourself into the squatting position, the erector spinae muscles of the lower back work to keep your spine stable and prevent rounding or curving. This is especially important for people who have a history of lower back pain or injury, as proper form during squats can actually help to alleviate discomfort and improve mobility.

The Importance of Squats for Building Leg Muscles

The Importance of Squats for Building Leg Muscles

Enhances Lower Body Strength

Squats are one of the best exercises for building leg muscles. They work the muscles in your thighs, hips, and glutes, making them stronger. The increased strength in your lower body muscles can help you perform everyday activities with greater ease.

Increases Muscle Mass

Incorporating squats into your workout routine can help you build muscle mass. Squats work large muscle groups in the legs, which promotes the growth of lean muscle tissue. As you increase your muscle mass, you will burn more calories and enjoy a faster metabolism.

Improves Balance and Stability

Squats require a high level of balance and stability. As you perform the exercise, you engage the core muscles in the abdomen and lower back, which helps you maintain proper form. Over time, this improved stability can translate into better balance in other areas of your life.

Boosts Athletic Performance

Adding squats to your exercise routine can help you improve athletic performance. The increased lower body strength and muscle mass can improve speed, agility, and power, which is essential for sports like running, basketball, and tennis.


Squats are a highly effective exercise for building leg muscles and improving overall lower body fitness. Incorporating them into your regular workout routine can help you gain muscle mass, strengthen your core and legs, improve balance and stability, and enhance athletic performance.

The Benefits of Squats for Strength and Endurance

Strength Training

Squats are one of the most effective strength-training exercises you can do. They are a compound exercise, which means they work multiple muscle groups at the same time. Squats primarily work the glutes, quadriceps, hamstrings, and calves, but they also activate the core, back muscles, and upper body. By doing squats regularly, you can increase your overall strength and power, which can improve your performance in other exercises and activities.

  • Builds muscle mass in the legs and glutes
  • Strengthens core and back muscles
  • Improves balance and stability

Endurance Training

Squats can also be used to improve your endurance. By doing high reps of squats with lighter weights, you can increase your muscular endurance, which means you will be able to perform physical activities for longer periods of time without getting tired. Squats are also an effective cardio exercise, as they increase your heart rate and stimulate the cardiovascular system, helping you to improve your overall fitness level.

  • Increases muscular endurance

  • Burns calories and promotes weight loss

Experts say, incorporating squats into your workout routine can have a variety of benefits for both strength and endurance training. By regularly doing squats, you can strengthen your lower body, improve your overall fitness level, and enhance your performance in other exercises and activities.

How to Perform Squats for Maximum Muscle Engagement

Proper Form

To engage the maximum amount of muscles during squats, it’s crucial to perform the exercise with proper form. Begin by standing with your feet shoulder-width apart, keeping your toes pointed slightly outward. Engage your core, and keep your chest up and your shoulders back. As you squat down, keep your knees aligned with your toes, and aim to lower your hips until your thighs are parallel to the ground. Come back up by pushing through your heels and squeezing your glutes at the top of the movement.

Engaging the Glutes

To focus on engaging your glutes, try adding some weight to your squats. You can either hold a weight in front of your chest, or place a barbell across your shoulders. As you lower yourself into the squat, focus on driving through your heels and imagining that you’re driving your hips forward. This will help you engage your glutes more effectively.

Working the Hamstrings

To engage your hamstrings during squats, aim to keep your weight shifted back towards your heels. This will help you work your hamstrings more effectively as you push yourself back up to standing. Additionally, you may want to try adding some Romanian deadlifts or glute-ham raises to your workouts to specifically target your hamstrings.

Engaging the Core

To engage your core during squats, it’s important to maintain proper form throughout the exercise. Keep your core engaged by actively squeezing your abs and glutes as you lower yourself into the squat. Additionally, you can try contracting your core even more strongly by adding some anti-rotation exercises to your routine, such as plank variations or Pallof presses.

  • Remember to start with a weight that’s appropriate for your fitness level, and to increase the weight gradually as you get stronger.
  • If you experience any pain or discomfort during squats, stop and consult with a qualified trainer or healthcare professional.


Squats are an effective way to engage multiple muscles in the body, including the quads, glutes, hamstrings, and core. By focusing on proper form and adding weight to your squats, you can maximize muscle engagement and reap the benefits of this versatile exercise.
