Roller massagers are handheld devices designed to relieve muscle tension and promote relaxation. They typically feature a cylindrical shape with a textured surface that can be rolled over various body parts, such as the back, legs, and arms. These massagers can be made from materials like plastic, wood, or foam, and they often come in different sizes and designs to suit individual preferences. Using a roller massager can help improve blood circulation and reduce soreness after physical activity. Many people incorporate them into their wellness routines, alongside other practices like stretching and yoga, to enhance overall muscle recovery and relaxation.
