Work on core energy and back muscles while you sleep.
The Front to Back™ dedicated tone box focuses on balancing and maintaining the muscles in your core and back. Back muscles give power to the body, playing a major role in all the body’s functions. They connect the hips, butt, chest, shoulder and neck.
This box is perfect for women who are pregnant.


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.
