The Core Ab Isolator F2 offers this muscle group’s highest possible degree of isolation. It is ideal for anyone looking to develop powerful abdominal muscles. Unlike other machines, the Core Ab Isolator F2 neutralizes the hip flexors, effectively isolating the abdominal muscles while relieving the strain on the lower back. The footplate is adjustable from the sitting position and adapts to the body size and bending angle of the legs. The difference to conventional abdominal machines is significant and immediately noticeable: more pressure on the abdomen, better training, safer use, and more effect with the same effort.
