How you hold yourself all day, everyday is how your body learns to stay. Learn the movement skills to choose and maintain a better posture and rid yourself of bad habits.
The constant mindset of, "More is better" will only lead to more of what ails us. If movement creates pain, then more of that movement will create more pain. The first step out of this cycle is changing the way you move to be more efficient. Our goal is to make our functional movement pain free.
Like software and hardware, your brain needs to understand how your body is moving and vice versa. Miscommunication leads to poor movement patterns and possibly injury.
