Abdominal muscles support the torso, allow movement, and hold organs in place by managing internal abdominal strain. They encircle and support the spine and pelvis, while connecting a person’s upper and lower body, essentially transferring forces from one to the other. A strong core also leads to better balance and stability, whether you are performing daily activities or engaging in vigorous physical exercise. The Fab Abs™ dedicated tone box is designed to work on core energy and abdominal muscles while you sleep.
 
Unlike on regular tone boxes, the frequencies are preprogrammed and should work for anyone seeking to use them. Includes a pair of Koss headphones for comfortable listening to the frequencies.
