How to Do Bodyweight Squats to Build Power and Functional Strength

If you were stranded on a desert island and could only do one lower-body exercise for the rest of your life, the bodyweight squat would be hard to beat. It requires no equipment, can be done anywhere, and is a compound movement that works multiple muscle groups at once. Plus, the bodyweight squat is one of the most essential human movements—sitting down and standing up, which builds strength in the leg muscles you rely on every day.

Whether your goal is to boost performance, build muscle, or stay strong and active as you age, bodyweight squats deliver. Studies show they can increase lower-body strength, improve joint stability, and support better movement patterns from the ground up.

“Bodyweight squats are arguably the most relevant exercise we perform with benefits to strength, mobility, and athleticism,” says Wendie Green, LPTA and Clinic Director at Bethesda Physical Therapy.

In this article, we’ll cover what muscles bodyweight squats work, the benefits of bodyweight squats, how to do them correctly, and share the best variations to help you build strength, mobility, and athleticism.

How to Do Bodyweight Squats with Perfect Form

1. Stand tall with your feet about shoulder-width apart and toes slightly turned out.
2. Engage your core, keep your chest upright, and maintain a flat back.
3. Push your hips back first as if sitting into a chair.
4. Bend your knees and lower your body with control.
5. Keep your heels flat on the floor and your weight centered over your midfoot.
6. Lower until your thighs are parallel to the ground (or as deep as your mobility allows without losing form.)
7. Drive through your heels to return to a standing position.
8. Complete 3 to 4 sets of 10 to 20 reps. Rest for 60 to 90 seconds between sets.

“The most frequent error in this movement is knee valgus (knees caving in), which increases joint strain and kills glute activation,” explains Sautter. “To fix this, consciously drive your knees outward so they track directly over your toes.”

What Muscles Do Bodyweight Squats Work?

Research shows that bodyweight squats recruit nearly every major muscle in your lower body, while also engaging your core to keep your spine stable and support good posture.

“While often viewed as a leg day staple, the squat is actually a compound movement that recruits a massive amount of muscle mass. They primarily target the quadriceps (front of thighs), glutes (buttocks), and hamstrings (back of thighs). They also can be beneficial to your core, lower back, and calves,” says David Sautter, NASM-certified personal trainer and sports-conditioning specialist at Muscle Booster.

Here’s a breakdown of the muscles most involved:

• Quadriceps: Located at the front of your thighs, your quads drive the upward phase of the squat by helping to extend your knees as you stand back up.
  
• Glutes: Your glute muscles power hip extension, especially as you push through your heels to return to the standing position during a squat
  
• Hamstrings: These muscles support your glutes and help control during the lowering phase of the movement.
  
• Adductors (Inner Thighs): Your adductors (inner thigh muscles) stabilize your hips and help maintain knee alignment as you squat.
  
• Core and Lower Back: When squatting (with proper form), your ab muscles and spinal stabilizers are engaged to help maintain a neutral spine and prevent you from leaning forward and putting strain on your lower back.

Benefits of Bodyweight Squats

1. They Can Build Lower-Body Strength and Muscle

Bodyweight squats target your quads, glutes, and hamstrings, helping to improve strength and muscle endurance, especially when performed with higher reps or with a slow, controlled tempo.

2. They May Improve Mobility

Research suggests that moving your joints through a full range of motion under control can help maintain flexibility and joint health. Deep squats, when done with proper form, can enhance mobility in your hips, knees, and ankles.

3. They Can Boost Balance and Coordination

Because squats require your hips, knees, ankles, and core to work together, they improve neuromuscular coordination, which is an essential component of athletic performance and injury prevention.

4. They May Reduce Injury Risk

Strengthening the muscles surrounding your hips and knees helps improve joint stability. According to a 2025 meta-analysis, lower body strength is associated with reduced fall risk and improved functional capacity as you age.

“Leg strength is a measurable marker that is an indicator of longevity and directly correlates to a decreased risk of falling in aging populations,” says Green.

5. They Can Improve Performance in Other Lifts and Sports

Building strength through bodyweight squats creates a foundation that carries over to other essential exercises, such as barbell squats, leg press, and deadlifts, as well as athletic movements like jumping, sprinting, and changing direction.

5 Bodyweight Squat Variations to Level Up Your Training

Once you’ve mastered the standard bodyweight squat, these variations can increase intensity, improve balance, and build strength in different planes of motion.

How to Do Lateral Squats

1. Stand with your feet wider than shoulder-width apart.
2. Shift your weight to one side and push your hips back as you bend the knee on that side.
3. Keep the opposite leg straight with your toes pointed forward.
4. Lower until your working thigh is roughly parallel to the floor.
5. Drive through your heel to return to center, then repeat on the other side.

How to Do Jump Squats

1. Stand with your feet shoulder-width apart and your core braced for stability.
2. Lower into a controlled squat, keeping your chest up and your weight centered.
3. Drive explosively through your midfoot to jump straight up, fully extending your hips and knees in the air.
4. Land softly by absorbing the impact through your feet and immediately sinking back into the next rep.
5. Maintain total bodily control throughout the transition to ensure you aren't wobbling or shifting weight on the landing.

How to Do Pistol Squat

1. Stand on one leg with your other leg extended straight in front and arms out for balance.
2. Hinge your hips back and lower slowly, keeping your chest up and the hovering leg clear of the floor.
3. Descend as deep as your mobility allows, ideally until your hamstring touches your calf.
4. Drive hard through your planted heel to return to the start, keeping your core braced to stay steady.

How to Do Split Squats

1. Step into a staggered stance with your feet about hip-width apart and your torso upright.
2. Lower your hips straight down by bending both knees until your back knee hovers just above the floor.
3. Keep your front shin nearly vertical and your weight centered as you descend.
4. Drive through your front heel to return to the starting position, keeping your core braced to prevent wobbling.
   

How to Do Box Squats

1. Stand with your feet shoulder-width apart, facing away from a sturdy bench or box.
2. Hinge at your hips and sit back slowly until your glutes make full contact with the surface.
3. Pause for two seconds to kill your momentum, ensuring you don't rock backward or lose core tension.
4. Drive through your heels to explode back up to the starting position, fully extending your hips at the top.
