Abstract: A bar preferably formed of tubular aluminum is formed to have a yoke and extensions for holding the shoulders of a user in a neutral position for exercising. Trunk twists and bends may be performed using the bar to maintain positions of the arms and torso for maximum effectiveness of the exercises. The bar is configured for adding weight inside or outside and particularly at its ends for increasing the rotational moment of inertia of the bar to give the effect of greater weight. End caps are configured to conveniently secure weights within or around the bar, by friction and threaded engagement. Weight materials include water, shot, cylinders, wheels and annuli configured as dead weights. The weight greatly enhances the moment of inertia when the bar is in motion during exercises, and can also be used with a leverage advantage to increase its effectiveness over conventional dead weights.

Abstract: Disclosed is an exercise device 10 including an elongated upright ladder section 14 which has at an upper end a body support section. There is a base 12 adapted to rest on a horizontal surface and support in a stable, vertical orientation the upright section. The body support section includes a seat rest support member 16 oriented substantially horizontally and adapted to be sat upon by a user and a second support member spaced from the seat rest support member and adapted to be gripped by the user with either legs or hands depending on the exercise being performed. A generally flat, planar, back support 84 has its upper end pivotally mounted to the seat rest support member 16 and a lower free end movable between a first position where the back support is generally vertical and a second position where the back support pivots and is at an acute angle with respect to the upright section 14.
