How to Brace Your Core Correctly for Squats

Bracing your core for a heavy squat isn't about just “thinking” about it or sucking in your stomach. It’s a physical skill you have to learn, just like the squat itself. This guide gives you the exact, repeatable steps to build a rock-solid brace that protects your back and adds pounds to your lift.

Key Takeaways

• To brace correctly, take a deep belly breath and push your stomach *out* in all directions, not suck it in.
• A proper brace creates intra-abdominal pressure, which can increase your squat strength by 10-15% by stabilizing your spine.
• The goal is 360-degree tension around your entire midsection, like an unopened can of soda, protecting your front, sides, and back.
• Do not exhale during the hardest part of the lift; hold your breath from the descent until you are almost standing up straight again.
• Practice the “brace for a punch” cue: tense your entire core as if you are about to be hit in the stomach.
• You must re-brace for every single rep in a set; do not try to hold one breath for multiple reps.

What Is Core Bracing (And What It Isn't)?

To learn how to brace your core correctly for squats, you have to forget the advice to “suck your stomach in.” Bracing is the exact opposite. You are not trying to look thin; you are trying to become an immovable pillar of strength. Think of your torso as a can of soda. An empty, open can is easy to crush. A full, sealed can is incredibly strong and can support a lot of weight. Your goal is to turn your torso into that full, sealed can.

This is achieved by creating something called Intra-Abdominal Pressure (IAP). In simple terms, IAP is pressure created inside your abdominal cavity that pushes outward on all sides. This pressure acts like an internal weightlifting belt, supporting your lumbar spine from the front. When you have a heavy barbell on your back pushing down, this internal pressure pushes back up, keeping your spine rigid and safe.

This is fundamentally different from the “hollowing” or “drawing-in” maneuver you might hear about in yoga or Pilates. Hollowing involves pulling your navel toward your spine. This is great for activating the deep transverse abdominis muscle in a non-loaded state, but it’s terrible for a heavy squat. Hollowing shrinks the “soda can,” making your torso smaller and weaker under load.

Bracing involves every muscle in your midsection working together. It’s not just about flexing your six-pack abs (rectus abdominis). It’s about creating a 360-degree wall of tension using your abs in the front, your obliques on the sides, and your spinal erectors in the back. When you do it right, your entire midsection from your ribs to your hips becomes a solid, unmoving cylinder.

Why 'Sucking In' and Other Cues Fail

You've probably been given bad advice before. It's why you're here. Most common cues for core engagement are wrong for heavy lifting and actively make you weaker and more prone to injury.

First, let's kill the worst offender: “suck your stomach in.” When you suck in, you decrease the volume and pressure inside your abdomen. You are literally making the “soda can” smaller and weaker right before you put a heavy load on it. This forces your lower back muscles (spinal erectors) to do all the work of stabilizing your spine, which is why so many people get that sharp pain at the bottom of a squat.

Another failed cue is to just “flex your abs.” This is better than sucking in, but it's incomplete. When you only flex the front of your stomach, you create a forward crunching motion. This can cause your upper back to round and your hips to shoot up too fast on the way up, turning the squat into a “good morning.” You've created a wall in the front but left the sides and back of your torso completely exposed.

Many people also misuse lifting belts. They think a belt is a passive support that just holds them in. This is wrong. A belt is a tool to give your brace something to push *against*. If you don't know how to create IAP, a belt is just a leather accessory. You have to actively push your stomach and sides into the belt to make it work. If you suck your stomach in while wearing a belt, you've completely defeated its purpose.

Finally, the cue to “breathe out on the way up” is a disaster for heavy squats. The concentric (upward) phase of the squat is the hardest part. Exhaling at this moment releases all of your IAP, instantly destabilizing your spine when you need support the most. It’s like letting all the air out of a car tire right before driving over a pothole.

The 3-Step Method to a Perfect Brace

This isn't a vague concept. It's a physical, repeatable process you will do for every single heavy rep of squats, deadlifts, and overhead presses. Follow these three steps, and your brace will become automatic.

Step 1: The 'Big Air' Breath

Before you even begin to descend, you need to get the air in the right place. Do not take a shallow breath into your chest. Your shoulders should not rise. Instead, breathe deep into your belly. Imagine you have a balloon in your stomach and you want to fill it with as much air as possible. Your stomach should visibly expand forward, and you should feel your sides and even your lower back expand outward. This is the fuel for your brace.

Step 2: The 'Brace for a Punch' Cue

Once you have that big belly full of air, lock it down. Now, perform the most important part: tense every muscle in your midsection as if you are about to be punched in the stomach. This is not a crunching motion. It is a hardening motion. Your abs, obliques, and lower back should all contract at once, creating that 360-degree wall of tension. You are actively trying to push that air you just inhaled outward against your wall of muscle. Your midsection should feel incredibly tight and solid.

Step 3: Hold, Squat, and Reset

Hold that breath and that tension through the entire repetition. Do not let any air escape. Descend into your squat, hit depth, and drive back up. Only once you are about one to two inches from the top of the lift, you can begin to exhale forcefully. Stand up straight, reset, and repeat the entire 3-step process for your next rep. For a set of 5 reps, you will take 5 separate breaths and perform 5 separate braces. You never hold one breath for an entire set.

Drills to Practice and What to Expect

Knowing the steps is one thing; feeling them is another. Use these drills to master the sensation of a proper brace before you even get under a heavy barbell.

Drill 1: The Fingertip Test

This is the best way to get instant feedback. Stand up straight and place the tips of your thumbs on your lower back muscles (spinal erectors) and wrap your fingers around to your sides to rest on your obliques. Now, run through the 3-step bracing sequence. Take a big belly breath and then brace for that punch. You should feel your fingers and thumbs being pushed *outward*. If you only feel your abs in the front get tight, you are not creating 360-degree pressure. Keep practicing until you feel that outward expansion against your hands.

Drill 2: The Goblet Squat Brace

Practicing with a light load makes the feeling more obvious. Grab a light dumbbell (15-35 pounds for men, 10-20 pounds for women) and hold it in the goblet position against your chest. The anterior load naturally forces you to engage your core to avoid falling forward. Now, perform your squats while consciously executing the 3-step brace on every single rep. Focus on the feeling of your stomach pushing out against the air you've trapped.

What to Expect

• Immediately: The first time you brace correctly under a barbell, the weight will feel noticeably lighter. You will feel more stable and powerful, especially out of the bottom of the squat. It's common for lifters to hit a new personal record the first day they learn to brace properly. An increase of 10-15% on your working sets is realistic.
• First Week: You will likely feel soreness in your abs, obliques, and even your lower back. This is not the same as pain from injury. It's muscle soreness from using these muscles in a new, more intense way. This is a sign you are doing it correctly.
• First Month: The bracing sequence will become second nature. You won't have to think through the steps so deliberately. Your squat form will become more consistent, your confidence will grow, and any nagging lower back discomfort you used to feel should be gone.

Frequently Asked Questions

Do I need a lifting belt to brace my core?

No. You must learn how to brace correctly without a belt first. A belt is an amplifier, not a creator, of pressure. Once you can squat 1.5 times your bodyweight with a perfect brace and feel your core is the limiting factor, a belt can help you get to the next level.

Should I hold my breath for the entire set?

Absolutely not. You must take a new breath and re-brace at the top of every single rep. Trying to hold one breath for a set of 5 or more reps is dangerous, will cause your form to break down, and can lead to you passing out under the bar.

My back still hurts. What am I doing wrong?

If you are 100% certain you are creating a 360-degree brace, the issue may be elsewhere. The most common culprit is poor ankle or hip mobility causing your lower back to round at the bottom of the squat (known as “butt wink”). A brace helps, but it cannot fix a significant mobility restriction.

Can I use this brace for other lifts?

Yes. This exact bracing technique is the foundation of spinal safety for all heavy compound lifts. You should use the same 3-step process for heavy deadlifts, overhead presses, bent-over rows, and any other exercise where your spine is under a heavy load.
