According to physical therapist Frank D’Ambrosio, "The sitting position is where most of us get into trouble with poor postural habits." Whether time is spent working at a desk or seated in a classroom, the head, neck and spine should be in line so that there is an even balance of weight across all three areas. This can be achieved by sitting straight, back against the chair and feet flat on the ground. Where possible, use adjustable chairs. If the chair is not adjustable, a small cushion or towel at the lower back can prohibit slouching.

For standing, walking or running, proper posture begins with the feet. "USA Today" suggests that shoes can help improve or destroy posture, depending on the type and style. Shoes that are too flat, such as flip flop sandals, as well as those with sky high platforms or heels, should be worn infrequently. High heels offset the body’s center of gravity and flip flops can do damage to the spine by not supporting the feet as they strike the ground. Shoes that are comfortable and stable will support the back and enhance good posture over time.

Sitting in the car is unlike sitting at a desk or in a chair for long periods of time because many of the body’s joints are simultaneously at work. Improving driving posture should begin with a seat that is well adjusted to fit the driver’s height. This means that the driver should be far enough from the pedals that the legs are not cramped; and far enough from the steering wheel so that the upper body does not slump forward or lean on it. The headrest plays an important role in keeping the neck in line with the spine. As such, it should be positioned at or above eye level.
