Running is often thought of as a purely forwards-and-backwards movement.
But your trunk is constantly rotating as you run.
A big part of that movement comes from the thoracic spine, working alongside the pelvis and shoulders to allow the body to move efficiently through each stride.
So I don't just want runners to have strength through flexion and extension. I also want them to have the capacity to rotate and control rotation.
This becomes particularly relevant with trail and ultra running, where uneven terrain, climbing, descending and changes in direction place different demands on how you control your trunk.
That doesn't mean you need to consciously “rotate more” when you run.
It's about having enough strength, mobility and control to handle the movement that's already there.
Build capacity in every direction.
