Deep tissue massage targets deeper layers of muscle and connective tissue using slow, firm pressure to release chronic tension, knots (adhesions), and scar tissue, offering relief from pain, spasms, and stiffness, often beneficial for athletes, chronic pain sufferers, and those with injuries, though it may cause soreness for a day or two afterward. Therapists use techniques with fingers, elbows, or forearms to work into tight areas, promoting healing and increased range of motion.
