How do you maintain perfect posture if your hips hurt?

It's a common misconception, but there is no such thing as perfect posture. Research has shown that perfect posture doesn't exist and people can actually experience posture-related pain in what we often refer to as perfect posture. Generally speaking, it's important to just sit comfortably. Add some variety to your day so that you sit in a variety of positions. It's okay to sit by leaning forward a little and flexing your spine. Remember, it's important to just get up and move. If you hold any position for too long, it's going to cause discomfort.
