2. Wall Sit
One of the main things exercises do for ankylosing spondylitis is to improve posture. We’ll get into posture a little more later, but this specific exercise is designed to improve posture. You begin with your back against a wall. Put your feet shoulder-width apart and slowly slide down the wall until you’re in a sitting position. “It may take time, but work towards being able to get to the point where your thighs are parallel with the floor — like you’re sitting in a chair,” writes WebMD. Hold this position for 5 to 10 seconds. As you get stronger, you’ll be able to hold the position for longer and longer. Do 3 to 5 repetitions at a time and practice it anywhere from 3 to 5 times a week.
