ABSTRACT:
An exercise apparatus includes a base, a substantially U-shaped member, and a substantially U-shaped handle element. The base can be configured as pair of individual foot members. The U-shaped member and handle element are pivotally connected to the base at different positions. A head rest is connected to the U-shaped member at a position intermediate the ends thereof. The pivotal connections can include a resistance producing element. A linking member is pivotally connected to each side of the U-shaped member and the U-shaped handle element. Adjacent sides of said U-shaped member and U-shaped handle are connected by the linking member. The position of the linking member can be adjusted as necessary in order to alter the angular disposition of the U-shaped member relative to the U-shaped handle element.
