A mobility and exercise system includes a user support platform, a leg platform connected to the user support platform, a first linearly movable mount and a second linearly movably mount each coupled to the leg platform and movable relative to the leg platform in two directions parallel to a longitudinal axis of the leg platform. A first abducting arm and a second abducting arm are coupled to the leg platform, each by a respective hinge. The first and second abducting arms are movable relative to the leg platform by swinging motion away from the longitudinal axis and back toward the longitudinal axis. A first foot cradle is mounted on the first linearly movable mount or the first abducting arm, and second foot cradle is mounted on the second linearly movable mount or the second abducting arm.
