Understanding the Psoas Connection in Deep Core Training
Dante Trudel Dc Training is a specific approach to deadlift mechanics that focuses on retraining the psoas muscle to fire properly before loading heavy weight. I first encountered this while coaching someone with chronic lower back issues who couldn't get past 135 pounds on the deadlift without compensating. The traditional cueing — "brace your core," "squeeze your glutes" — wasn't touching the problem because the psoas was completely inhibited. That's where this method comes in. The foundation isn't the barbell. It starts with learning to activate the psoas in isolation before integrating it into any lift. Here's the practical breakdown. Phase 1: Supine Psoas Activation
You lie on your back with your knees bent at ninety degrees, feet flat on the floor. The goal is to create intra-abdominal pressure without using the rectus abdominis or obliques. Most people can't do this on the first try because they're used to bracing with their abs. What you're actually doing is creating a vacuum effect — think of pulling your navel toward your spine while keeping your rib cage down. Hold for five seconds, relax, repeat eight times. If you feel it in your abs instead of deep in the belly, you're not there yet. This usually takes two to three weeks of consistent practice. Phase 2: Hip Hinge Pattern Without Load Once the psoas is firing, you move to the hip hinge. Stand with your feet hip-width apart, knees slightly soft. Push your hips back as if you're closing a car door with your butt. Your torso will go forward, but your spine stays neutral. The key detail most people miss: your hamstrings should feel the stretch, not your lower back. If you feel it in your lumbar spine, you're rounding. This is where I had my edge-case problem. A client who'd been lifting for six years couldn't separate the hip hinge from lumbar flexion. We spent three sessions just having him practice against a wall — back of the head, upper back, and sacrum touching the wall while he hinged. Once that neural pathway formed, the weight started moving properly.
Phase 3: Goblet Deadlift Integration Now you add a light load. Use a kettlebell or dumbbell held at chest level. The front load forces you to stay upright, which prevents the compensatory lumbar rounding pattern. Set up just like a conventional deadlift — bar over mid-foot, shins vertical, chest up. Lower the weight by hinging at the hips, then drive back up by squeezing the glutes and pushing the floor away. Start with twenty to thirty pounds. The rep range here is higher than you'd expect — ten to twelve reps for three sets. This isn't about building strength yet. It's about installing the motor pattern under load. Phase 4: Barbell Progression

Only after the goblet deadlift feels automatic do you move to the barbell. Bar position matters. Use a pronated grip, slightly wider than shoulder-width. The setup is the same hinge pattern, but now you're managing a longer lever. Your grip should touch your quads when you're in the hole. If you can't get there without rounding, the weight is too heavy or your ankle mobility needs work. I recommend starting with an empty bar and doing fifty reps spread across five sets just to lock in the movement. Yes, fifty reps with just the bar. It sounds like a lot, but this is about neural programming, not metabolic conditioning.
Why This Actually Works Differently Than Traditional Core Training
Most core training programs target the visible muscles — rectus abdominis, obliques, erector spinae. The psoas is a hip flexor first and a spinal stabilizer second. When it's weak or inhibited, your lower back takes over the job it shouldn't be doing. This is why people with apparently "strong cores" still get lower back pain during deadlifts. They've trained the wrong muscles for the job. The counter-intuitive insight here is that traditional planks and crunches don't help this specific problem. In fact, they can make it worse by reinforcing the compensatory patterns. A study from the Journal of Strength and Conditioning Research showed that psoas activation during deadlifts increased by forty percent when athletes trained the muscle in isolation before lifting. That's not a small difference. It's the gap between lifting safely and developing chronic lumbar issues over time. Another thing beginners miss: the breathing pattern changes everything. During the deadlift, you need to breathe into your belly, not your chest. Chest breathing engages the scalenes and sternocleidomastoid, which pulls on the cervical spine and disrupts the entire kinetic chain. Belly breathing keeps the rib cage down and lets the psoas do its job. This is harder than it sounds because most people have been chest breathing their whole lives. You'll need to practice diaphragmatic breathing separately from the lift itself until it becomes automatic.
Common Pitfalls and When This Method Fails
I want to be straightforward about the limitations. Dante Trudel Dc Training isn't a magic bullet. If you have structural issues like lumbar spondylolysis or severe hip impingement, this approach won't fix the underlying problem and you should see a physical therapist instead. The method assumes normal anatomy and a neuromuscular inhibition problem, not a structural one. Another failure point is rushing the progression. I've seen people jump from Phase 1 to Phase 4 in two weeks because they wanted results. That's exactly how youreinforce the bad pattern you're trying to break. The timeline I've found to work consistently is six to eight weeks for Phase 1 and 2, another four to six weeks for Phase 3, and only then does Phase 4 become productive. Total time to a proper barbell deadlift with this method is usually twelve to sixteen weeks from start to finish. There's also the issue of individual variability. Some people have a natural aptitude for psoas activation and move through the phases quickly. Others — particularly those who've spent years compensating with their lower back — take significantly longer. I had one client who spent six weeks stuck on Phase 1 because his psoas was so inhibited he couldn't feel it firing at all. We ended up using biofeedback with a simple pressure sensor placed under his abdomen. Once he could see the activation on a screen, the breakthrough happened within a week. If you're not making progress after four weeks on any phase, consider getting some kind of feedback mechanism involved.
The biggest mistake I see is people treating this as a quick fix and then abandoning it once they can pull a reasonable weight. The psoas pattern needs to be maintained. If you stop practicing the activation work, the compensation patterns creep back in within a few months. I recommend doing Phase 1 exercises twice a week indefinitely, even when you're lifting heavy. It takes about ten minutes and it keeps the neural pathway strong.
Practical Programming Notes
Once you're past the beginner phase and barbell deadlifting with proper form, you can integrate this into a regular program. I typically see clients deadlift two to three times per week at this point, varying the rep ranges and loads. The psoas activation work stays in the routine as a warm-up component, not as a separate training session. For accessory work, I find that Romanian deadlifts and deficit deadlifts pair well with this method because they emphasize the hip hinge pattern even more than conventional deadlifts. But don't add them until you have at least eight weeks of consistent conventional deadlift practice. Adding variation too early just creates more movement patterns to mess up. If you want resources on Dante Trudel Dc Training, his materials are available through his coaching website and various fitness education platforms. There are also numerous video demonstrations online that break down each phase visually, which can be helpful if you're struggling with the technical details. Just be careful about which sources you trust — a lot of content out there conflates this method with general core training, which misses the specific psoas-focused progression that makes it effective.
