When someone tells me they hurt their back — lifting, moving a sofa, picking up a grandchild — the first thing I test is whether they can brace. Almost nobody can. Not properly, not under load, not while also doing something else with their body.
It's the most useful thing I teach and the thing almost nobody has been taught.
What bracing actually is
Intra-abdominal bracing is how you pressurize your trunk so that your spine stays where you put it while you move something heavy.
The plain version: take air into your belly and crunch down at the same time, the way you would if you knew you were about to take a punch to the gut. That's it. That's the feeling you're looking for.
The mechanism underneath: you breathe into the belly rather than the chest, your diaphragm drops, pressure rises inside the abdominal cavity, and your deep abdominal wall contracts around that pressure to contain it. The result is a rigid, pressurized middle — a column your spine sits inside rather than a hinge it bends at.
Sucking your stomach in is not bracing. It's the opposite of bracing.
Pulling the navel toward the spine is a cue from a different world — it narrows the cavity and reduces the pressure you're trying to build. Under a loaded bar it leaves you less protected, not more.
How to do it
- Breathe into your belly, not your chest. Put a hand on your stomach and one on your ribs. The bottom hand should move first and move more. If your shoulders rise, the air went to the wrong place.
- Take about 70 percent of a full breath. Completely full and you can't contract against it. This isn't a maximal inhale, it's a working one.
- Expand in every direction. Not just forward. Front, sides and back — think of inflating a ring around your waist rather than pushing your belly out.
- Now tuck down. Like the start of a standing crunch — ribs down, a slight bracing contraction through the whole trunk. This is the part people miss. Air alone isn't a brace; the contraction against it is.
- Hold it for the rep. You keep the pressure through the hardest part of the movement and breathe between reps, not during them.
The belt test
Here's where most people go wrong, and it's worth understanding before you spend money.
A belt does nothing on its own. It is not a back support and it isn't holding anything together. It's a surface to brace against. Wrapped firmly around your waist, it gives your abdominal wall something to push into, and pushing into it is what raises the pressure further than you could manage unassisted.
Which is why people who buy a belt after hurting their back often hurt it again. They bought the equipment and skipped the skill, and a belt worn by someone who can't brace is just a tight accessory.
It also gives you a way to check yourself, which is the best use of a belt for a beginner:
- Fasten a lifting belt firmly — tight, but you can still breathe.
- Expand your belly against it, in every direction.
- If the belt gets tighter, you're bracing correctly. If nothing changes, the air went to your chest.
- Then tuck down. That tuck is the brace.
Ten seconds, and it removes the guesswork. You can do it standing in a kitchen with no weight anywhere near you.
If you don't own one, a plain 4-inch leather lifting belt is all you need — no padding, no contouring, nothing clever. This is the one I point people to on Amazon →

Watch it
Reading about a feeling only gets you so far. Here's the whole thing, taught:
How to brace your core for squats
Brace standing, before you unrack. Take the breath and the tuck while the bar is still on the hooks, then walk it out already pressurized — not after you've got it on your back and you're trying to find your feet.
Hold it all the way down and all the way up. The bottom of a squat is where the pressure matters most and where people most often let it go. Breathe at the top, between reps. On a heavy set that means one breath per rep, not one per set.
How to brace your core for deadlifts
Different problem: you're already bent over when the lift starts, so you have to brace in that position.
Set your feet, take your grip, then take the breath and the tuck before you pull — with your hips down and your back already in the position you intend to keep. Bracing after the bar leaves the floor is too late; the moment you most need the pressure is the moment it breaks the floor.
Hold it through the whole rep. Reset at the top or on the floor between reps, whichever your programming calls for.
How long until it's automatic
I can teach the technique in one session. Being strong enough to hold it under real load takes most people around six months of actual training.
That's not a reason to wait — it's the reason to start light. The first weeks of lifting should be about building the brace while the weight is forgiving, which is why I start everyone in a higher-rep block. Twelve reps is twelve chances to practise it. Five is five.
If your back already hurts
If you have current back pain, a disc problem, or a diagnosis affecting your spine, see a professional who can examine you before you load anything. Bracing is protective, but it isn't a treatment, and some conditions need assessing before any of this applies.
And if you've been hurt before, this is worth learning with someone watching you. It's a feeling, and feelings are hard to self-diagnose from a page.
Then go and use it
Bracing is step one of three: brace, then technique, then load. Once it holds, the lifts are next — I've put free coaching for the squat and deadlift up alongside this video, no signup.
And if you want the week it all goes into, there's a full weight training routine written out, sets, reps, rest and all.
Brace. Then get strong.
