A frame for body stretching exercises comprising a pair of U-shaped tubular legs hinged together at their open ends to form a support with their bight portions opposite from their open ends, detent means for limiting the separation of the legs when they are opened by spreading their bight portions apart, an upper generally U-shaped frame hinged to the legs at their open ends, and body supports extending across the legs and across the frame. Detent means are included to maintain the upper frame in co-planar alignment with one of the legs when the upper frame is extended, the frame may be released and swung to lie substantially co-extensively with the legs.
