A balance disc is a piece of exercise equipment that creates an unstable base for you to sit or stand on while exercising. The lack of stability from the disc forces you to engage your deep abdominal core muscles in order to maintain stability while you perform various exercises. Twisting abdominal exercises work the oblique muscles, which run down the side of your stomach. Adding a medicine ball to the exercise routine can help you to tone up quicker when combined with a balance disc.
