Beyond the usual sit-ups and crunches, there are other effective abdominal exercises. These are "roll" movements that can typically be done with an "ab wheel". The Dual Handle Ab Wheel promotes high isolation of the abdominal muscles, thereby maximally engaging them. It's important to "round" your back to fully contract these specific muscle groups (especially the lower back).
The Dual Handle Ab Wheel is a piece of equipment that acts as an "abdominal stabilizer". In this exercise, abdominal contraction is also regulated by breathing. This involves inhaling deeply and trying to hold your breath throughout the entire repetition.
