How can I effectively massage or stretch my muscles to relieve tension and improve flexibility?

To effectively relieve muscle tension and improve flexibility through massage or stretching, focus on applying gentle pressure to the muscles, using long, smooth strokes. Incorporate deep breathing to help relax the muscles and increase blood flow. Stretching should be done slowly and gradually, holding each stretch for 15-30 seconds. It's important to listen to your body and avoid pushing too hard to prevent injury. Regular practice of these techniques can help reduce tension and increase flexibility over time.
