If you slouch a lot, there's a good chance your back is rounded. This position puts more stress on your spine and the muscles in your back and shoulders. Pilates exercises can help you get an arch in your back.
Remember to use lateral breathing -- expanding your ribcage sideways as you breathe in -- and keep your abdominal muscles tight throughout these exercises.
