Squats are a highly effective compound exercise for targeting multiple muscle groups in the body. While the primary muscles targeted are in the lower body, the core muscles and muscles above the waist are also engaged during the movement. The specific muscles worked can vary depending on the type of squat performed, such as bodyweight squats, back squats, or jump squats, each offering unique benefits and challenges.

What You'll Learn
Quadriceps
Squats are a fantastic way to target and build muscle groups, burn calories, and enhance power, strength, and endurance. They are considered to be one of the most effective exercises for building lower body strength, improving athletic performance, and promoting overall fitness.
The quadriceps, or quads, are one of the primary muscle groups targeted by the squat movement. The squat exercise activates all four heads of the quadriceps: the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.
The squat movement involves hinging at the hips, bending at the knees, and lowering the body while keeping the back straight, chest up, and core tight. This movement pattern specifically targets the quadriceps as they are responsible for knee flexion, which is the action of bending the knee joint.
To focus on building quadricep strength through squats, it is recommended to keep the squat depth to less than 90 degrees. Additionally, performing different variations of squats, such as jump squats, back squats, or bodyweight squats, can help target the quadriceps from different angles and increase the challenge.
Overall, incorporating squats into your workout regimen is an excellent way to strengthen and tone the quadriceps, as well as improve lower body strength and overall fitness.

Hamstrings
The hamstrings are made up of three muscles: the biceps femoris, the semitendinosus, and the semimembranosus. They cross two joints, the hip and the knee, and can therefore perform actions at both joints. When the hamstrings contract, they bend the knee backward, which is known as "knee flexion". They also help to thrust the hips forward, which is called "hip extension".
During squats, the hamstrings are only slightly active, helping to stabilise the knee and transmit forces. This is because, during a squat, the hamstrings do not change in muscle length, and so the stress and tension on them are very mild. Research has shown that training muscles in a long and stretched-out position leads to more muscle gain than when trained in a shorter muscle length.
The hamstrings are only recruited near the top of the squat to assist the hips from extending up and forward. They are most active during the first stage of the descent into a squat, when you first begin to bend your knees (120 degrees or less of) knee flexion. After this, they are not used much at all.
According to a study in the European Journal of Applied Physiology, researchers measured how much the hamstrings were activated during the leg press, an exercise that closely mimics the squat. They found that the hamstrings were only 25% as active during the exercise as the quadriceps.
Therefore, if you are looking to target your hamstrings, exercises such as leg curls, stiff-legged deadlifts, and good mornings are more effective than squats.

Glutes
Squats are a great way to target and grow specific muscle groups, burn calories, and enhance the power, strength and endurance of lower-body muscles. They are also an effective body-resistance exercise that works the lower body and can help with daily tasks such as sitting in a chair or bending down.
The glutes are a primary mover in the back squat, and the exercise targets the gluteus maximus, gluteus medius, and gluteus minimus to enable hip extension. The gluteus medius, or side butt muscle, is often overlooked, but it can be targeted by tilting the torso forward at a 45-degree angle with hands clasped in front of the chest, stepping out with the left foot, and then the right, repeating the pattern, and reversing the movement to return to the start, staying low throughout.
The back squat is often considered the gold standard for enhancing athletic performance, as it requires the coordinated interaction of numerous muscle groups. It places an emphasis on the glutes and hips while still targeting the quads.
To target the glutes, a basic squat can be performed with a dumbbell held at chest height, with feet a little wider than hip-width apart, and toes pointed out. The shoulder blades should be pulled toward the spine, with eyes forward and a neutral head posture. The glutes should be squeezed, and the movement is completed by pushing the feet apart and descending as though sitting into a chair, before returning to the starting position.
For a more challenging HIIT workout, a jump squat can be performed, which is a plyometric move that requires the muscles to be exerted to their maximum potential in a short period of time. This variation puts more stress on the joints, so it is important to have healthy knees, hips, and ankles.

Calves
The calf muscles, also known as the gastrocnemius, soleus, and plantaris, are crucial during the squat movement. These muscles are responsible for plantar flexion, which occurs when you point your toes downward. During a squat, the calves are recruited isometrically to stabilise the ankle and foot and keep the lower legs stable.
The gastrocnemius has a medial and lateral head, which can be seen right below the knee on the back of the leg. The soleus is in front of the gastrocnemius, and both muscles run down to the Achilles tendon.
If your goal is to build muscle or strength in the calves, the barbell squat is particularly useful. Jump squats, which involve performing the squat motion and then jumping as high as you can, are another exercise that directly targets the calves.
The calves also help with knee stabilisation. You use your calves when pushing from the lowest position of a squat.

Core
Squats are a great way to strengthen your core and improve your overall fitness. They are a compound exercise, meaning they work multiple muscle groups at once, including those in your lower body and core muscles.
The core muscles targeted by squats include the rectus abdominis, obliques, transverse abdominis, and erector spinae. By strengthening these muscles, you can improve your balance, ease lower back pain, and maintain better posture.
To ensure you are engaging your core during squats, it is important to maintain proper form. This involves keeping your back straight, chest up, and core tight as you hinge at the hips and bend at the knees.
Additionally, you can vary the type of squat to target your core muscles differently. For example, the back squat adds resistance to the shoulders with a barbell, while jump squats increase your heart rate and target the glutes, quads, hips, and hamstrings.
By incorporating squats into your fitness routine, you can effectively engage and strengthen your core muscles, leading to improved stability, balance, and overall physical performance.

Frequently asked questions
Squats target a wide range of muscles in the body, with an emphasis on the lower body, including the quadriceps, hamstrings, glutes, calves, and core muscles.
The back squat, for example, works the upper back and shoulder muscles. Other variations of squats, such as the overhead squat, also target the arms, chest, and back.
Targeting these muscle groups can improve your balance, ease lower back pain, enhance athletic performance, and make everyday movements like standing up and sitting down easier. Additionally, squats can help build bone density and improve flexibility, which is especially important for older adults.
While squats are highly beneficial, performing them incorrectly or overtraining without proper recovery can lead to injury. It is important to focus on proper form, maintain a balanced workout routine, and allow for adequate rest days.
