This is where we interact with the ground when standing, so a stable foundation results in better postural control. Improved core activation also helps to improve posture without you really having to think about it…

When the deeper core muscles are activated, you’ll be standing straighter simply because of which muscles are automatically co-activated: pelvic floor, deep six in the hips, TFL, psoas, diaphragm, etc. Better posture also results in greater movement efficiency, meaning better performance and less chance of injury caused by muscle imbalances.

COOL STUFF, huh?
