You’ve probably seen some guy at the gym loading up four plates on each side, descending about two inches, and then grunting like he just conquered Everest. That’s not a squat. Honestly, it’s a recipe for a blown disk and a lifetime of telling people "I used to lift heavy until my back gave out." If you want to know how to squat with a barbell the right way, you have to park your ego at the door. It’s a violent, beautiful, technical movement that recruits almost every muscle in your body, but it’s also one of the easiest things to mess up if you’re just winging it.
Most people think it’s just sitting down and standing up. It isn't.
The set-up is where you win or lose
Before the bar even touches your back, you’ve already decided if the rep will be successful. Step one is the rack height. If you have to go on your tiptoes to unrack the weight, it’s too high. You’re asking for a disaster when you try to re-rack a heavy set while exhausted. Set the hooks so the bar hits around your mid-chest or armpit level. This allows you to "wedge" yourself under the bar with your feet firmly planted.
Grip width matters way more than people realize. If you have the shoulder mobility, a tighter grip helps create a "shelf" of muscle on your upper back for the bar to sit on. If you're stiff, go wider. Just make sure your wrists aren't cocked back like you're carrying a tray of drinks. You want a straight line from your elbow through your wrist to the bar. Pull your shoulder blades together. Hard. Imagine you’re trying to crush an orange between your wings. This creates the stability you need to prevent the bar from rolling around or crushing your vertebrae.
Now, the unrack. Don't just stumble backward. Take a deep breath into your belly—not your chest—and stand the bar up. Step back with one foot, then the other, then a small adjustment to find your stance. This "three-step walkout" is the gold standard for high-level powerlifters because it conserves energy. If you're dancing around with 200 pounds on your back for ten seconds, you're wasting the fuel you need for the actual lift.
How to squat with a barbell: Finding your perfect depth
There is a massive debate about "butt wink" and "squatting to parallel." Let’s get real. Unless you have the hip anatomy of an Olympic weightlifter, forcing yourself to go "butt to grass" might actually be doing more harm than good. When your hips tuck under at the bottom (that's the butt wink), your lumbar spine rounds under load. That is bad news for your L4 and L5 discs.
Dr. Stuart McGill, a world-renowned spine biomechanics expert, often points out that everyone's hip sockets are shaped differently. Some people have deep sockets (the "Celtic hip") which makes deep squatting literally, anatomically impossible without bone-on-bone contact. Others have shallow sockets that allow them to fold up like a lawn chair.
You need to find the depth where your back stays flat. For most, that means the crease of your hip drops just below the top of your kneecap. That is a legal "parallel" squat. It’s enough to trigger massive hypertrophy in the quads and glutes without turning your spine into a Slinky. If you can't get there, the issue is usually ankle mobility. If your ankles are stiff, your heels will pop up, your knees will dive forward, and you'll feel like you're falling over.
The breathing trick that changes everything
Stop breathing through your mouth like you're running a marathon. You need the Valsalva maneuver. This sounds fancy, but it’s basically what you do when you’re trying to poop or lift a heavy couch. You take a huge belly breath, hold it, and brace your abs outward.
- Take air into your stomach.
- Tighten your core as if someone is about to punch you.
- Hold that pressure through the hardest part of the lift.
- Exhale only once you've cleared the "sticking point" on the way back up.
This internal pressure creates a "fluid ball" in your abdominal cavity that supports your spine from the inside out. Without it, you’re just a wet noodle trying to support a steel bar. It's the difference between a rigid pillar and a collapsing tent.
High bar vs. Low bar: Which one is for you?
You have two main choices for bar placement.
High bar squats sit the barbell on top of your traps. This keeps your torso more upright and puts the emphasis on your quads. It’s what most athletes and bodybuilders do. It feels more natural for most beginners, but it can be harder on the knees if you have a history of patellar tendonitis.
Low bar squats, favored by powerlifters, involve placing the bar across the rear deltoids. This requires you to lean forward more, which brings the hamstrings and glutes into the fight. You can generally lift about 10-15% more weight this way because you're using the massive muscles of your posterior chain. However, it requires a lot of shoulder flexibility. If your shoulders feel like they're going to snap when you reach back, stick to high bar for now.
Common mistakes that are killing your gains
The most common sin is the "Good Morning" squat. This is when your hips rise faster than your chest, turning the lift into a weird, dangerous back extension. This usually happens because your quads are weak, so your body tries to shift the load to your stronger lower back. If this is happening to you, strip the weight off. Use a weight where your chest and hips rise at the exact same time.
Then there’s the "knee cave." If your knees are shaking and drifting inward as you stand up, your glute medius isn't doing its job. Think about "screwing your feet into the floor." Imagine there is a piece of paper between your feet and you are trying to tear it in half by pushing your feet outward without actually moving them. This engages the hips and keeps your knees tracking safely over your toes.
Why footwear is the most underrated factor
You cannot squat in squishy running shoes. I mean, you can, but you shouldn't. Running shoes are designed to absorb impact. They have foam midsoles that compress. When you have a barbell on your back, you want a rock-solid foundation. Squatting in Nikes or Adidas runners is like trying to lift a heavy weight while standing on a giant marshmallow. You lose power, and your ankles become unstable.
Get yourself some flat-soled shoes like Converse Chuck Taylors or dedicated weightlifting shoes with a raised wooden or hard plastic heel. The raised heel helps if you have poor ankle mobility, allowing you to stay more upright. If you're on a budget, honestly, just squat in your socks. Anything is better than a compressed air bubble under your heel.
Practical steps to a better squat
Don't just jump into the heavy stuff. Start with a thorough warm-up that focuses on the hips and ankles.
- Bodyweight prying: Sit in the bottom of a squat and use your elbows to push your knees out. Stay there for 30 seconds. Feel your hips open up.
- Goblet squats: Hold a dumbbell or kettlebell against your chest. This acts as a counterweight, making it easier to stay upright and find your balance before you move to the barbell.
- The empty bar: Do at least two sets with just the 45-pound bar. This is your time to "grease the groove" and make sure your nervous system knows the movement pattern for the day.
- Incremental loading: Add weight in small jumps. If you're doing a working set of 200 lbs, don't go from 45 to 200. Go 45, 95, 135, 165, then your working weight.
Squatting is a skill, not just an exercise. You have to practice it like you'd practice a golf swing or a guitar solo. Record yourself from the side. Look for bar path—the bar should move in a straight vertical line over the middle of your foot. If it's swinging forward toward your toes, you're off balance.
Actionable insights for your next session
To truly master the barbell squat, you need to stop thinking about "up" and start thinking about "back and down."
- Focus on the tripod foot: Keep your weight distributed between your big toe, little toe, and heel. Don't let your toes lift.
- Fix your gaze: Don't look at the ceiling and don't look at your feet. Pick a spot on the floor about six feet in front of you. This keeps your neck in a neutral position.
- Pull the bar down: Don't just let the bar sit on you. Actively pull it into your traps with your hands. This engages your lats and makes your entire upper body a solid unit.
If you hit a plateau, don't just add more weight. Change your tempo. Try "pause squats" where you sit at the bottom for three seconds before standing up. This removes the "bounce" or stretch reflex and forces your muscles to do all the work from a dead stop. It’s brutal, but it works.

Stop worrying about what the person on the next rack is doing. A perfectly executed 135-pound squat will build more muscle and keep you in the gym longer than a shaky, half-assed 315-pound ego lift. Mastery comes through repetition and a relentless focus on the boring details. Fix your setup, breathe into your belly, and keep your chest up. Everything else is just noise.
To move forward, start by filming your very next set from a side-angle at hip height. Watch for the relationship between your hips and knees; if your hips move first and "shoot out," reduce the weight by 10% and focus on a synchronized ascent. Incorporate two sets of "prying" goblet squats into every warm-up to ensure your hip capsules are mobile enough for the depth you need. Consistency in the setup—using the exact same foot placement and hand width every single time—will build the neurological patterns necessary to make heavy weights feel light.
