Trigger point balls are small, firm balls designed to relieve muscle tension and pain. They are often used in self-myofascial release, a technique that helps release tight knots in muscles, known as trigger points. By applying pressure to these points, users can improve blood flow and reduce discomfort. These balls come in various sizes and materials, allowing for different levels of pressure and intensity. They can be used on various body parts, including the back, neck, and feet. Regular use of trigger point balls can enhance flexibility and promote overall muscle recovery.
