When you have back pain, exercises might be the last thing everyone wants to do. However, some simple stretches and physical exercises would actually help with pain relief. Some low-impact options to consider for people with back pain include water exercises, yoga, brisk walking, tai chi, or swimming laps. They would help loosen your tense muscles and produce endorphins, a natural painkiller in your brain. Over time, your back also gets more flexibility and strength to prevent occurring problems in the future.
