Why We Address Movement Before Load

You can't build a strong structure on a broken foundation. Corrective work isn't a detour from your training — it's what makes your training safe to progress.

Most people arrive at training with years of accumulated movement habits — from sitting at desks, looking at screens, carrying bags on one shoulder, favouring one side during sport, or recovering from old injuries. These patterns become deeply ingrained, and the body compensates around them so efficiently that most people don't notice them at all.

The problem is that when you add load to a compensated pattern, you don't just train the muscle — you reinforce the dysfunction. A squat performed with knees caving inward doesn't just build legs. It builds legs while stressing the knee joint in a way it isn't designed for. A chest press with rounded shoulders doesn't just build the chest. It builds the chest while loading the shoulder in an impingement-prone position.

Corrective exercise identifies these patterns early, addresses them systematically, and ensures that as you get stronger, you're getting stronger in the right positions — not just getting better at moving badly under heavier load.

What Corrective Work Is Not

The Bigger Picture

Every physique result, every strength goal, and every performance target is built on top of how well you move. Clients who address their movement patterns early don't just avoid injury — they progress faster, feel better in training, and build the body they're after more efficiently than those who simply load compensated patterns harder.

How Corrective Exercise Works

Every corrective intervention follows the same four-step sequence. The order matters — each step prepares the system for the next. Skipping steps is why most people's attempts at self-correcting don't stick.

01
Inhibit
Reduce tension in the overactive muscle using foam rolling or targeted pressure. Prepares the tissue to accept length without protective guarding.
02
Lengthen
Stretch the muscle that's been holding too much tone. After inhibition, it accepts length far more readily and the gains are more likely to hold.
03
Activate
Wake up the underactive muscle — the one that stopped doing its job because something else took over. Isolated, light load work to re-establish the neural connection.
04
Integrate
Load the corrected pattern in a real movement. The first compound exercise of your session typically serves this role — your body learns to maintain the correction under load.
Why This Sequence Works

Most people jump straight to strengthening the weak muscle — which often doesn't work because the overactive muscle is still dominating the pattern. You have to release what's too tight before you can activate what's too quiet. That's the logic of the sequence, and it's why the order is never skipped.

Where It Lives in Your Session

Corrective work is built into the structure of your programme — not bolted on. You'll find it in your warm-up, in specific activation exercises before the main workout, and occasionally as the first movement of a training block. Most clients spend 5–10 minutes on it per session. As your patterns improve, this reduces naturally.

Rounded Shoulders & Forward Head Posture

Upper Body
Forward Head & Rounded Shoulders
The most common pattern in desk workers, phone users, and anyone sitting for long periods

When you spend hours sitting with your head forward and your chest closed — at a desk, looking at a phone, driving — the muscles at the front of your body gradually shorten and tighten. The muscles at the back that are supposed to hold your posture upright become long, stretched out, and stop doing their job effectively. Over time, this becomes the default position your body returns to.

In training, this shows up as rounded shoulders on pressing movements, difficulty with overhead work, neck and upper back tension that persists between sessions, and shoulder discomfort that limits range on pulling movements.

What You Might Notice

Head sits forward of your shoulders when viewed from the side
Shoulders round forward naturally at rest
Upper back and neck tension — especially after desk work
Arms don't reach fully overhead without the lower back compensating
Shoulder discomfort during or after pressing movements
Difficulty feeling mid-back muscles working during rowing movements

What We Do About It

01
Release
Foam rolling the thoracic spine and sustained pressure on the upper traps and chest. This reduces the protective tension that's been building — the tissue becomes receptive to the length work that follows.
02
Open
Chest stretches at multiple angles, upper trap stretches, and thoracic extension over the foam roller. Opening the front of the body is what creates the space for the back to come back online.
03
Activate
Band pull-aparts, chin tucks, and prone raises to wake up the mid-back, lower traps, and deep neck muscles that have been underworking. These are often in your warm-up already.
04
Reinforce
Every rowing and pulling movement in your session reinforces the corrected pattern — if done with the right cue. "Shoulder blades into your back pockets" is the integration happening in real time.
The Daily Habit That Makes the Biggest Difference

No amount of corrective work in a session will outpace hours of poor posture at a desk. The single most impactful daily habit: stand up every 60–90 minutes, do 10 chin tucks and a doorway chest stretch, and reset your sitting position when you return. Two minutes, done consistently, compounds more than most people expect.

Anterior Pelvic Tilt

Lower Body
Anterior Pelvic Tilt
The pelvis tips forward — common in anyone who sits for long periods

The hip flexors are a group of muscles at the front of the hip responsible for pulling the thigh toward the body. When you sit for long periods, they shorten and stay in a contracted position. Over time, they become the dominant force at the hip — pulling the front of the pelvis downward and tipping it forward. The lower back arches excessively to compensate, the glutes and core become inhibited, and the body loses the ability to hold a neutral pelvis position under load.

This pattern is one of the most common reasons clients struggle to activate their glutes effectively — and one of the primary drivers of lower back discomfort during training. Addressing it often produces an immediate improvement in how hip thrusts, squats, and deadlifts feel.

What You Might Notice

Lower back arches excessively — visible gap between back and wall when standing against it
Hip flexor tightness — pulling sensation at the front of the hip, especially after sitting
Lower back discomfort during or after training
Difficulty feeling glutes working — lower back tends to take over instead
Forward lean in squats — torso tips forward rather than staying upright
Heels rise in squats — can be hip flexor tightness pulling the pelvis forward

What We Do About It

01
Release
Foam rolling the hip flexors, TFL (outer hip), and inner thigh. Slow, deliberate passes — pausing on tender spots. This begins to reduce the chronic tension that's been shortening these muscles.
02
Lengthen
Half-kneeling hip flexor stretches with a posterior pelvic tilt correction — tailbone tucked before driving the hips forward. Pigeon pose for the deep hip. 30 seconds each side, consistently applied.
03
Activate
Glute bridges with a deliberate squeeze and hold at the top. Dead bugs to re-establish core activation. Clamshells with a band to target the glute medius. These are often in your warm-up already — they're there for this reason.
04
Reinforce
Hip thrusts, goblet squats, and Romanian deadlifts all integrate the corrected pelvic position. The cue you'll hear throughout: "Tuck your tailbone slightly — neutral pelvis, not arched." That's the pattern being reinforced in real time.
The Connection to Your Glute Goals

Anterior pelvic tilt is the single most common reason clients struggle to build their glutes despite consistent training. If the hip flexors are dominant and the pelvis is tipped forward, the glutes are mechanically disadvantaged before the set even starts. Addressing pelvic tilt isn't a detour from your glute development — it's the prerequisite for it.

Knee Valgus — Knees Caving Inward

Lower Body
Knee Valgus
Knees collapsing inward during squats, lunges, and single-leg movements

When the knees collapse inward during lower body movements, the knee joint is absorbing rotational force it isn't designed to handle. In isolation, a single repetition with mild valgus isn't a crisis. Across hundreds of repetitions under increasing load over months of training — it becomes a meaningful injury risk, particularly to the ACL, meniscus, and patellofemoral joint.

The pattern is driven by a combination of tight inner thigh muscles pulling the knee inward, and underactive glute muscles that should be holding the knee in line but aren't doing so effectively. It's more common in women due to differences in hip anatomy — but it appears across all clients and is consistently addressable with the right approach.

What You Might Notice

Knees drift toward each other at the bottom of a squat or lunge
One or both knees track inward when stepping down stairs
Knee discomfort during or after squatting — particularly at the inner or front of the knee
Difficulty keeping knees out when cued — the correction feels effortful and doesn't hold
Inner thigh tightness that pulls the leg inward even at rest
One side worse than the other — asymmetrical weakness is common

What We Do About It

01
Release
Foam rolling the inner thigh and outer hip. Slow passes through the inner thigh where tension accumulates. This reduces the pull that draws the knee inward before you've even started moving.
02
Lengthen
Adductor stretches and hip external rotation stretches — opening the inner hip to reduce the inward pull. 90/90 hip stretches are particularly effective here, targeting both the tight inner thigh and the restricted hip rotation simultaneously.
03
Activate
Banded clamshells and lateral band walks to target the glute medius — the primary muscle responsible for keeping the knee aligned. Banded squats where the band provides resistance to collapse also work well. You'll feel this in the outer hip if you're doing it right.
04
Reinforce
Every squat, lunge, and leg press becomes the integration — with deliberate cuing to "push the knees out" or "drive the floor apart." Over time this becomes automatic. The cue disappears because the muscles are doing the work on their own.
Why Cueing Alone Isn't Enough

Many coaches simply tell clients to "push your knees out" — and the client does, temporarily, because they're thinking about it. But once attention goes elsewhere, the knees cave again. That's because the muscles responsible for holding the position aren't strong enough yet. Cueing controls the symptom. Corrective exercise fixes the cause.

What to Expect

Movement quality improves faster than most people expect — when the right things are addressed in the right order, consistently.

Corrective progress doesn't always feel dramatic in the moment. You won't notice the day your knees stop caving in squats the way you notice a new personal best on a deadlift. But it shows up — in reduced discomfort, in better activation, in exercises feeling different in the right places, in movements becoming easier that used to feel restricted.

Typical Progression

When to Tell Me Something Has Changed

If you notice new discomfort, pain during an exercise, or a sensation that feels different from the normal effort of training — say so immediately. Pain during exercise is never something to push through. Corrective work addresses dysfunction, not injury. If something crosses into pain territory, we refer to the right professional and adjust your programme accordingly.

The Long-Term View

The clients who invest in movement quality early always look back and consider it one of the best decisions they made. Not because it was exciting — it rarely is — but because it's what allowed them to train hard, train consistently, and build the body they were after without the setbacks that derail most people's progress.
