Abstract
An exercise apparatus for strengthening the abdominal muscles, upper legs, and back comprises a large engagement surface and a pair of handles angled away from a body to provide stability. The portable exercise apparatus utilizes a slide member slidably positioned in a channel of a yoke and biased in one direction by an elastic cord. A base, which is positioned at one end of the slide, is placed against the abdomen or the buttocks while the user pulls the yoke towards the abdomen or buttocks by grasping the handles mounted astride the slide. The user contracts the abdominal or buttocks muscles while pulling the hands toward the abdomen or buttocks to hold the apparatus stationary. Strengthening of the abdominal or buttocks muscles is achieved by moving the abdomen or buttocks against the biasing force of the elastic cord.
