ABSTRACT:
A back exerciser is portable, stores in a collapsed position, accommodates people of all different sizes, and allows one to safely exercise all the muscle groups in one's back using resistance provided by one's own weight. First and second pairs of support legs are pivotally connected together at one end of each. Pivotal movement between a collapsed position and an operative position in which the legs of the supports have an angular relationship of about 45.degree.-75.degree. with respect to each other is provided, with positive stops supporting the legs in their maximum angular orientation. The first legs have an angle of about 20.degree.-30.degree. to the vertical. A platform is mounted for movement between a first position in which it is between and parallel to the legs of the first support, and a second position in which it is generally horizontal and disposed above the second support legs. With the platform in the first position one can exercise one's upper back by standing on rungs extending between the legs of the first support legs, engaging the platform with one's legs, and bending one's torso over the second support. With the platform in the horizontal position, one can exercise the lower back by laying on the platform, gripping the legs of the second support with one's hands, and raising one's legs separately or in unison to progressively tense the muscles of the lower back.
