A plank can tell us more than just how strong your core feels.
One metric we sometimes use is comparing a client’s plank hold with their back extension hold.
That gives us a simple ratio of anterior vs posterior trunk endurance, and whether one area may need more attention in their program.
It is not about chasing a perfect number.
It is about using testing to help guide smarter, more individual programming.
In this reel, I also go through how we set up a high plank properly, because position and control matter just as much as how long you can hold it.
