Here's How to Practice Perfect Posture:

-Stand with feet shoulder distance apart. 

-Don't lock your knees. Keep them slightly bent.

-Keep your pelvis in a neutral position. Avoid tucking your hips under or sticking your booty out too far. 

-Roll your shoulders up back and down.

-Stand with your chest in a tall position.

-Lengthen through the top of your head.

-Your ears ought to be over the middle of your shoulders. 

-Think of boney landmarks all in a line... ears, shoulders, hips, knees, ankles.

-Breath deeply in and out. Be sure to breathe into your belly and feel your ribs expand.

I hope you're reminding yourself regularly to sit up straight. Every little bit counts.
