Low back pain affects most people at some time in their lives.
The easiest way to avoid this discomfort is to keep your core strong.
Your core is more than just your abdominal muscles and is used in basically every movement of the body.
By strengthening your entire middle section, you will be taking undue stress off your spine, which will prevent pain and injury.
The good news is that you don't have to do sit-ups! There are many alternative exercises which work equally well or better when it comes to strengthening your core. Your middle will feel more stable and your spine will be able to function properly as the pillar of support for your body's weight.
