The single biggest fix we make with lifters and general fitness clients dealing with lower back pain isn’t a stretch, an adjustment, or a special exercise. It’s teaching them to hinge from their core instead of their back. Get this one thing right and you’ll lift heavier, hurt less, and buy your spine another 30 years of hard training.
What “hinging” actually is
A hip hinge is any movement where you push your hips backward and let your torso tip forward as one rigid unit. Your knees stay soft but relatively still. Your spine stays neutral. Your hips do the work.
You hinge every time you pick something up. Every deadlift, every Romanian deadlift, every kettlebell swing, every barbell row, every good morning, every hip thrust setup. You hinge when you tie your shoes. When you load the dishwasher. When you pick your kid up off the floor.
If you do it well, your posterior chain (glutes, hamstrings, spinal erectors) shares the load evenly and your spine stays protected. If you do it poorly, your lumbar spine takes the beating and you’re on the road to injury.
The mistake almost everyone makes
Most people don’t actually hinge. They flex their lumbar spine. It looks like this: they bend forward, their lower back rounds, and their hips barely move backward. The load ends up sitting on their spinal discs and lumbar erectors instead of on their glutes and hamstrings.
The tell: at the bottom of the movement, their belt line curves like a hook, their shoulders are far in front of their toes, and their hamstrings feel almost nothing.
Do this enough times, at enough load, and you get exactly what we see all the time at RXN Performance: lower back pain, disc issues, chronic tightness, and people who “used to lift” but had to stop.
Why your core is the key
Your “core” isn’t just your abs. It’s the full 360-degree pressure system around your spine: your transverse abdominis, obliques, diaphragm, pelvic floor, and multifidus all working together to create intra-abdominal pressure.
When you brace your core correctly, you create what’s essentially a rigid pressurized cylinder around your spine. That cylinder does two things:
1. It transmits load away from your spine. Force from a heavy deadlift doesn’t crush your discs — it disperses through your braced trunk into your hips and legs.
2. It keeps your spine neutral under load. A properly braced core makes it physically hard to flex your lumbar spine. It’s automatic protection.
People who lift with a braced core lift heavier AND have less back pain. Not one or the other — both.
How to actually hinge with your core (step by step)
Step 1: Set up your feet and grip
Feet hip-width. Bar over midfoot. Grip is whatever’s comfortable for the lift you’re doing.
Step 2: Big breath into your belly BEFORE you lift
Take a huge breath in through your nose or mouth and push it down and out into your entire torso — front, sides, and back. Not chest breathing. This is 360-degree expansion. Your belly should feel like a full water balloon.
Step 3: Brace hard against the pressure
Now tense your entire trunk like someone is about to punch you in the stomach. This locks the pressure in. Your ribs shouldn’t flare up — they should stay stacked over your pelvis.
Step 4: Push your hips back, keep your spine neutral
Initiate by pushing your hips backward. Your torso should tip forward as one rigid unit, not fold at the low back. Your shoulders should stay in line with the bar. Feel your hamstrings loading up. If your hamstrings are silent, you’re not hinging — you’re bending.
Step 5: Drive through your feet and stand up
Squeeze your glutes and drive your feet through the floor. Keep the brace held the entire time. Don’t exhale until the top of the rep.
Step 6: Reset the brace between reps
Every rep gets its own fresh breath and brace. If you rush the reset, you lose the pressure and your back takes over.
The 3 fastest ways to know you’re doing it wrong
Test 1: Where do you feel it the next day?
If your lower back is toast and your hamstrings and glutes feel nothing → you’re using your back, not your hips.
Test 2: Film yourself from the side
Rounded lower back at the bottom = spinal flexion under load = wrong. Your belt line should stay flat or slightly arched, never curved into a hook.
Test 3: The hamstring test
At the bottom of any hinge, you should feel a strong stretch in your hamstrings. If you feel nothing there but your low back is tight, you’re hinging from the wrong place.
What to do if hinging hurts your back right now
Two possibilities: either you have a movement dysfunction that needs to be identified and fixed, or you’re just deconditioned in your posterior chain and need to build it up gradually. Both are fixable. Both need proper assessment first.
If your back is currently hurting when you hinge, don’t just push through and hope. Get seen. Full context on our approach: Lower Back Pain.
Once we identify what’s driving the pain, we build back up progressively: bodyweight hinges → kettlebell hinges → Romanian deadlifts → conventional deadlifts. Full deadlift ramp-up guide (with 4-step warmup): Pre-Workout Routine for Back Pain.
Real results from real patients
Ron came in with 5 years of chronic back pain and could barely deadlift 135. Six months later — after learning to hinge from his core, not his back — he pulled 295 for a triple, pain-free. His story: Ron’s story.
Kellie came in modifying F45 workouts because bending forward hurt. She’d been coached to “engage her core” for years without knowing what that actually meant. Once we taught her how to properly brace and hinge, she went back to 5 unmodified F45 sessions a week. Her story: Kellie’s story.
Frequently asked questions
Do I need to brace for every rep?
For any hinge under meaningful load — yes. For light warmup or bodyweight movement — a moderate brace is enough. The heavier the load, the harder the brace.
What about a belt?
A belt is a tool that amplifies a good brace. It doesn’t replace bracing. If you can’t brace without a belt, you have a bracing problem that needs training first. Use a belt for your heaviest working sets, not your warmups.
How do I know if my core is strong enough for what I’m lifting?
If your low back is what fatigues first on a set of hinges — before your legs or your grip — your core capacity is the limiter. Add dedicated core work: dead bugs, bird dogs, Pallof presses, farmer carries. Related: Hip Mobility for Lifters (mobility + strength both matter).
Does this apply to everyday lifting, not just the gym?
Yes — arguably more so. Most back injuries don’t happen in the gym under a barbell. They happen picking up a laundry basket while distracted. The hinge pattern is life insurance for your spine outside the gym as much as inside it.
What if I’m past 50 and want to start deadlifting?
Perfect time to start, actually. Loading a hinge pattern builds bone density and preserves the exact movement pattern that keeps you independent in your 70s and 80s. Start light, learn to brace, and progress slowly. Details: Training Through Your 50s and 60s.
