Bad posture aggravates musculoskeletal pain and creates tight, stiff, sore muscles.
Therefore, stretch, change positions, and have a good workstation that does not require too much leaning or reaching. Distribute heavy loads to stronger joints with a greater surface area, keep objects close to the body to provide leverage, minimize reaching, and don't put too much pressure on the lower back. Also, don't stay in the same position for too long. It improves our sense of well-being, strengthens muscles and bones, allows restful sleep, relieves stress, releases serotonin and endorphins, which decreases pain and burns calories. Start out with walking and then advance to other general conditioning programs such as swimming or bicycling.
