Or abdominals, referring to the muscles in the front of the stomach. While most people tend to think of the abs as only the rectus abdominus (the top layer of abdominals, commonly known as the "6 pack"), we actually have 4 layers of abdominals, the transverses abdominus, the internal obliques, the external obliques and the rectus abdominus. Pilates is an extremely effective form of exercise to strengthen and tone all the abdominals, not just the rectus abdominus.
