Most of us spend a lot of time sitting,so posture makes a big difference to our backs. Here are six ways to improve posture 1. Feet flat on the floor. Keep one foot, and preferably both feet, flat on the floor. Try this: Sit down and if you have a chair with a moving back, lock it in the upright position. Rest your hands in front of you on the desk, as if you are typing. Concentrate on the shape of the lower spine. Straighten your legs and place the feet on ground, on the heels of your shoes. See how your lower spine has changed shape-it’s moved slightly from the back of the chair. The muscles in the mid section of your back have to work to keep you sitting up straight. Now notice the lower back’s shape when you put your feet flat on the floor, with your knees at a 90 degree angle. It’s in contact with the back of the chair. Your mid-section back muscles are relaxed.
