There are some great ways that people can improve your posture. The first way is to become aware of your posture so you know what you need to fix. The second way is to use imagery by imagining that you have a string along your ribcage and spine. The third way is to align your ears and shoulders over your hips. The fourth way is to take care of your feet by massaging them on a daily basis. This is so your back will not sag. The fifth way is to keep the soles on your feet flat on the floor when you are sitting down.
The sixth way is to stay active by stretching every once in awhile if you have a seating job. The seventh way is to practice bending over and lifting things correctly. This means to bend and lift with your knees. The eighth way is to use a pillow in your chair to support your lumbar curve. The ninth way is to train your muscles how they are suppose to work. The tenth way is to be confident in yourself by distributed your body weight evenly across your feet.
These are just some of the great ways to improve your posture.
