Abstract
Disclosed is a back exerciser including a table having first and second separate, but adjacent sections aligned with each other so that the first section supports the torso of the person reclining on the table and the second section supports the lower body of such person. The second section is mounted to rotate about a vertical axis which is nearest the first section and positioned so that, with the person reclining on his or her sdiee on the table, the vertical axis intersects the greater trochanter of the person's leg. Means for securing the person to the table so that said person, while reclining on his or her side, may cause the second section to rotate about a vertical axis by bending the lower body relative to the torso. The second section is adapted to rotate either clockwise or counterclockwise about a vertical axis. A dynamometer is coupled to the table for measuring the muscular performance of the person's back muscles during rotation of the second section.
