Abdominal and lower back exercise apparatus

Year	Description
1996	Invention patented by Robert Amesquita on June 20th, 1996. Abstract: An abdominal exercise apparatus has an elongated rigid member for positioning between a user's back and a support surface for executing a crunch. A grasping mechanism, such as a strap member, is attached to the rigid member to allow the user to lift the head end of the rigid member from the support surface by contracting the abdominal muscles. A pivot member is connected to the rigid member adjacent the user's lower back and positioned to engage the support surface. A weight retaining mechanism, such as a post, adapted to receive weighted plates, may be attached to the rigid member to enhance the workout to the abdominal and lower back muscles.
