A two-position pivot support structure is disclosed for enabling a tiltable body exerciser to be tilted about a first or a second horizontally extending pivot axis, the first and second horizontally extending pivot axes being laterally spaced apart. The support structure includes an A-frame stand having left and right pairs of leg members mechanically intercoupled and mounting left and right trunion supporting plates. A first pair of left and right U-shaped trunion receiving slots and a second pair of left and right U-shaped trunion receiving slots are located, respectively, in the left and right trunion supporting plates. A stop member is mechanically joined between the front legs of the A-stand. With the left and right trunions of the tiltable body exerciser positioned, respectively, in the first pair of left and right trunion receiving slots, the tiltable body exerciser is operable to tilt the human body in an inclined, inverted and unlocked body position. With the left and right trunions positioned, respectively, in the second pair of left and right trunion receiving slots, the tiltable body exerciser is operable to tilt the human body in an inverted, locked, body position.
