Using a massage gun on the stomach can provide a variety of benefits, though it should be done with caution. The device works by sending rapid pulses of pressure into the muscles, helping to release tension, improve blood circulation, and promote relaxation. On the stomach, this can be especially useful after an intense workout, long hours of sitting, or if you're experiencing discomfort or tightness in the abdominal muscles. For those with digestive issues or bloating, the gentle vibration may help stimulate digestion and reduce the feeling of fullness.
