Aside from the obvious point that poor posture causes tension and can lead to injury, we also need to talk about how patterns and positions need to be universal in our lives, on and off the field.
When we are sitting all day in bad shapes (postures) we are practicing a pattern. A pattern that will transfer into every other movement we make. That means if we are sitting in a bad shape at the desk, we are probably going to default into that same shape when we train or pick up our kids, bringing obvious risks with it.
How scalable is this pattern?
Can we add load or speed to this? Can we do this repeatedly and come out unharmed?
If the answer is no, then there is little point in practicing it. While having our feet turn out when we walk or having bad posture in general isn’t dangerous now, it doesn’t scale or transfer well outside of the small window of a sedentary life. As soon as we step out and try to apply those patterns to things like running or jumping, we see a huge increase in tension and injury.
There are a lot of lifters who choose to deadlift with a rounded back and while this is still an okay position, it doesn’t transfer well into other situations and other sports. Performing as an athlete or in life, we still need movement options and this is where patterns that don’t scale or transfer well really limits us.
The concept is this:
