Back massagers are devices designed to relieve tension and pain in the back muscles. They come in various forms, including handheld massagers, massage chairs, and foam rollers. Many back massagers use techniques like kneading, tapping, or vibration to mimic the effects of a professional massage, helping to improve circulation and promote relaxation. These devices can be beneficial for people with sedentary lifestyles, athletes, or anyone experiencing back discomfort. Some models even offer heat functions to enhance the massage experience. Popular brands include HoMedics and TheraGun, which provide a range of options to suit different preferences and needs.
