Always imagine you have something delicate placed on your head. This will keep your head up and back straight. If imagination doesn’t work, try placing something real.
Maintain a good posture while standing and extend it to walk. Chin up, shoulders back, eyes straight, and chest out is the ideal posture.
Do not push your head forward.
Choose proper supportive footwear. If needed, choose the ones with comfortable padding, which could help you hold yourself erect. Additionally, the arches need good support too. Remember, good posture always begins with the feet.
Heels are something to be avoided since it can misalign your body.
If you want to stand for a long duration, add padding to the ground to give you extra comfort.
