The idea is to keep your body in perfect alignment, maintaining the spine’s natural curvature, with your neck straight and shoulders parallel with the hips.
Standing with a flat back – A flat back also tends to make you lean your neck and head forwards, which can cause neck and upper back strain.
Exercises to strengthen your core, buttocks, neck and rear shoulder muscles, and back extensions, are recommended to help correct a flat back.
Leaning on one leg – Over time, you may develop muscle imbalances around the pelvis area, which can cause muscular strain in the lower back and buttocks.
