Vicore's CORE AB is an effective piece of equipment designed for developing your mid-section injury free. This week's exercise clearly demonstrates just how versatile the equipment is.

Many products available for performing sit ups and crunches lack the proper ergonomics. Therefore, they place a great deal of pressure on the spine and tailbone. They also force the user to “jerk violently upward" at the start of each rep – a motion which isn't so great for the "Upper Cervical Ligaments.” Can you say whiplash? With the CORE AB, you are literally floating on air, eliminating tailbone or spinal pressure, making every motion smooth and fluid.
