An estimated 80-90 percent of the U.S. population will suffer from spinal pain at some point in their lives. According to the American Chiropractic Association, people who are overweight or obese, and who smoke, lift heavy objects, or had a previous episode of back pain, are more likely to experience back pain.

Here are a few tips from the ACA website that may help your back stay injury free:

When Standing ...

• When standing, keep one foot slightly in front of the other, with your knees slightly bent. This position helps to take the pressure off your low back.
• Do not stand bent forward at the waist for prolonged periods of time. The muscles in your low back become deconditioned in this position, which may lead to pain.

When Lifting ...

• At all times, avoid twisting while lifting. Twisting is one of the most dangerous movements for your spine, especially while lifting.
• If the item is too heavy to lift, pushing it is easier on your back than pulling it. Whenever possible, use your legs, not your back or upper body, to push the item.
• If you must lift a heavy item, get someone to help you.

When Sitting ...

• Keep your knees slightly higher than your hips, with your head up and back straight.
• Avoid rolling your shoulders forward (slouching).
• Try to maintain the natural curve in your low back.
