The "Just Do It" Fallacy

There is a stubborn belief in movement culture that the best way to improve a skill is simply to do the skill again and again. Want to run better? Run more. Want a cleaner squat? Squat more. Want better posture? Stand up straight until it sticks.

There is truth inside this. Skills do need practice. The body learns through repeated exposure to the real task. But repetition is not neutral. If the task is too loaded, too fast, too braced or too far beyond the body's current organisation, repetition may rehearse the very compensation you are trying to undo.

A baby does not begin with the final skill

Walking is not learned by being told to walk. It emerges from a long sequence of capacities: head control, rolling, sitting, reaching, pushing, crawling or crawling-like exploration, standing with support, standing alone and finally stepping. These milestones appear in broad, overlapping windows, and not every baby follows the exact same route. Even crawling is not universal. But the principle is consistent: complex movement is built from simpler systems that come online first.

Research on infant walking shows just how much varied practice is involved. In one study, toddlers averaged thousands of steps and many falls per day, moving in short, irregular bursts across changing environments. They were not drilling perfect reps. They were exploring constraints, adjusting balance, recovering, trying again and letting the nervous system solve the problem.

The problem is not practice. The problem is practising a solution your body only found by cheating.

Breath and core are coordination, not just strength

Before the body can express a skill cleanly, it needs internal organisation. The diaphragm is not just a breathing muscle. Research by Hodges and Gandevia showed that diaphragm and abdominal coactivation can raise intra-abdominal pressure, linking breathing to postural control. In plain language, how you breathe changes how the trunk supports movement.

This is why a collapsed ribcage, locked pelvis or held breath matters. The body may still complete the movement, but it will do so by borrowing stability from somewhere else: the jaw, neck, lower back, hip flexors or knees. The external skill appears to be happening. Internally, the pattern is expensive.

Repetition can train compensation

Compensation is not failure. It is the nervous system doing its best with the options available. If a stabilising muscle is underused, if a joint lacks range, if fatigue is high or the body feels unsafe, the system finds another route. That is intelligent in the short term.

The problem comes when the shortcut becomes familiar. Repeat a squat with a braced breath and collapsed pelvis, and the body may get better at that squat, not at the clean version you hoped for. Repeat running with a locked ribcage and overstriding, and you may build endurance on top of impact patterns that keep asking the tissues to absorb unnecessary force.

The smarter alternative: scale, restore, integrate

Motor learning research does not say "never practise the skill." It says practice needs the right constraints. The task should be specific enough to transfer, but scaled enough that the body can solve it cleanly. Load, range, tempo, support, feedback and fatigue all matter.

This gives us a practical sequence:

• Regulate first. If the nervous system is in threat, movement becomes rigid. Breath gives the body a way back into choice.
• Restore the missing pieces. Rebuild access to the pelvis, psoas, ribs, feet and deep stabilisers before asking the whole skill to improve.
• Scale the skill. Reduce load, range or speed until the body can perform without obvious compensation.
• Integrate gradually. Bring the pieces back together, then increase complexity only as long as the breath and structure stay available.

Mastery is not top-down

A skill is the visible expression of invisible organisation. Running, squatting, balancing and sitting with ease all depend on breath, sensory feedback, joint freedom, postural tone and the nervous system's sense of safety.

So yes, practise the skill. But do not confuse repetition with mastery. The best practice is not blind volume. It is the patient rebuilding of the conditions that let the body solve the task well.

Key takeaways

• Task-specific practice matters, but repetition without the right constraints can reinforce compensation.
• Infant movement shows that complex skills emerge from earlier postural, respiratory and coordination foundations.
• The cleanest path is to regulate, restore missing subsystems, scale the task, then integrate the full skill.
