An exercising apparatus in which the body is supported while being restricted to rotary movement of upper and lower torso portions one relative to the other. Restriction of movement isolates the abdominal muscle group while accomplishing “full range”exercise as herein defined. The apparatus includes an upper torso engaging backrest and a lower torso engaging backrest and seat so that the user is supported in a generally seated position. Weights and a variable cam provide a variable resistance force to pivotal movement when the upper torso engaging backrest and the lower torso engaging backrest and seat are moved toward and away from each other.
