The Ab wheels primary function is to increase total body performance with core-strengthening exercises.
Though it has the reputation of just targeting abdominal muscles during exercise, it in fact also targets your hip flexors, obliques and lower back muscles.
Exercises using the ab wheel require that your core muscles work together to properly execute the movement.When your core muscles become well balanced you are able to retain good posture and provide a solid, centered base.
Diet and aerobic exercise alone will not give your abdominal muscles the size and strength that all impressive six packs have. To build such size and strength the abdominal muscles have to be trained!
