At first glance, that statement probably sounds wrong.
However, rehabilitation and fitness aren’t as different as we’ve been taught to believe.
They absolutely do have different goals and different constraints. As a result, the decisions you make are often different.
But underneath all of that, they’re guided by the same underlying principles.
The body isn’t responding to the lines we’ve drawn.
It’s responding to what we’re asking it to do.
The type of demand we’re placing on it.
The magnitude of that demand.
Whether those demands are appropriate for where that person’s body is today.
And whether that body has the ability to tolerate them, recover from them, and adapt.
The same principles that help someone recover from an injury are the same principles that help someone build strength, improve performance, or stay active as they age.
A torn rotator cuff doesn’t get approached the same way as an off-season athlete trying to add muscle.
A 70-year-old who has never lifted weights doesn’t get approached the same way as a healthy 20-year-old.
The application is different because the person’s presentation is different.
The decisions are different because the person’s needs are different.
But the reasoning behind those decisions is the same.
You’re still trying to match the demands you’re placing on that person’s body to what it can successfully tolerate, recover from, and adapt to.
So… if the principles don’t change, what exactly are we separating?
