Remember, though, if you are experiencing back pain of any sort, check with a healthcare professional before doing these or any exercises. And do the exercise according to the medical advice rendered by that professional. Sciatica is the disease which affects nerves of the back. To control the back pain due to the nerve disease you must undergo strength training in physiotherapy.
If you understand the concepts of how backs get injured by bad back exercise habits you can easily tell if you are moving in healthy ways, if an exercise will help or harm, or if you're doing a good exercise in bad way. You're not helping yourself if all you do is a "list" of exercises. Worse, many people are given a list of things to never do again. This list is often favorite activities that made their lives worthwhile and fun.
Most people spend their lives doing activities with poor posture that rounds their lower back. They sit, stand, walk, and exercise round-shouldered and round-backed. This shortens chest and shoulder muscles in front, and over stretches and weakens your back. Like squeezing a water balloon in front, when you round forward, it squeezes the front of your discs between your back bones (vertebrae) above and below the disc.
