An exercizer device is provided which is light weight, portable and collapsible. The device is adjustable to accommodate users of various heights. There is a substantially rectangular frame with two pairs of support legs, one pair being pivotally mounted to the other pair, and the other pair being pivotally mounted to the frame. The frame consists of a pair of generally “U”-shaped members arranged in an opposing and telescoping relationship with securing means to adjust the relative positions between the U-shaped frame members. Across one end of one of the U-shaped members there is a cushion for supporting the lower end of the torso of a human body, while at the other end of the other U-shaped member there is a cross-piece for supporting the feet of the user. One of the pairs of the support legs in assembled position extends beyond the extent of the rectangular frame, whereby the lower portion of a human body can be supported on the frame while the upper portion can extend free and clear of the device to be raised or lowered in completing exercises.
