Inferior ab rollers beware!\r\n\r\nPerformance\r\nThe question is: does it perform? You\u2019re average, run-of-the-mill ab roller performs just fine. But it\u2019s missing something.

There\u2019s a carbon steel spring inside the wheel that provides extra resistance when you push and pull, giving your core muscles a much more efficient workout than ever before, including your lower back. The CAP Barbell is simply no match for it.\r\nDesign\r\nAs mentioned, the Perfect Fitness Ab Carver Pro is an ab roller, but not like your typical ab wheel. It\u2019s much wider in width, which really helps provide stability when you\u2019re rolling; otherwise falling on your face is inevitable. The handles are especially comfortable considering they curve and wrap just slightly around your hands for a safer grip. Unfortunately, it\u2019s simplistic in nature and only really provides one exercise method, though its single method is very effective. For a variety of exercise methods, the Star Uno Ab Machine might interest you more.\r\nValue\r\nIs the Perfect Fitness Ab Carver Pro worth nearly $30?

Furthermore, a knee pad is tossed in, which is much appreciated.\r\nPerfect Fitness Ab Carver Pro Wrap Up\r\nThe Perfect Fitness Ab Carver Pro proved to be a great evolution to the design of the ab wheel.
