Stability and strength
It often confuses people when their non-dominant leg is stronger on unilateral (single leg) movements.
Explaining this, and a little more will give you an insight into the importance of stability around joints.
Instability creates weakness and for the more endurance based trainees it creates inefficiency. A fairly simple concept to grasp. In anything related to performance you fundamentally want to be both strong and efficient.
Loosen the head on an axe and that single blow becomes less effective. Loosen the nuts on your car wheels and that 200 mile journey becomes inefficient. In both cases the likelihood of the axe or wheels actually breaking goes up significantly.
Now at this stage I’m not going to bang on about ‘postural correction’ as speculating that I’ll be able to fix something you do potentially 12-23 hours a day with 3-4 hours of gym sessions a week is nonsensical.
Making joints more efficient and stable will over time help to put the body into better alignment, reduce the risk of injury and make you a damn sight stronger.
In all of my years dealing with injuries the main issue is weakness through one of the planes of movement the joint is responsible for. This is a matter as a coach of understanding the planes the joint is responsible for and working the joint accordingly. Paying attention historically to what has been worked, under-worked and even potentially underworked.
People favour their strength which ultimately means they inevitably work them more than their weaknesses. It seems a fairly consistent thing in training populations.
In writing this I know this is something I’m certainly guilty of. In some cases as a coach you could analyse the equipment within a gym and note what movements aren’t being performed within that demographic. Most gyms you’ll find a dominance of movements in upper limb pronation and a lack of posterior lower limb movements. Don’t take my word for it.
Go take a look.
The issue we have here is the weak point gets weaker in comparison to the strong point. At some stage there is enough of a differential that injury occurs. What you’re doing right now is potentially injuring yourself in the future.
Ask anyone who’s injured. When they find out what caused it hindsight becomes a great thing.
A great coach creates foresight and can anticipate and identify imbalances, instability, weaknesses and strengths so that the likelihood of injury is minimised.
