Core/glute activation

Recently I’ve been working on activating my core and glutes at posture to not only help keep at consistent spine angle but to protect my lower back.

A lot of people including myself tend to arch their back at posture, which creates an “S” shape spine that could damage the lower back.
Although it isn’t easy to do as it sounds, I definitely recommend doing it to have a consistent swing and a prolonged golfing career!
