A freestanding exercise apparatus comprises a frame, a right door, a left door, and an exercise resistance source. The frame defines a sagittal plane dividing the frame into a left half and a right half with anterior and posterior ends. The right door is pivotally attached to the right half of the frame proximate the anterior end of the frame for pivoting about a right pivot axis. The left door is pivotally attached to the left half of the frame proximate the anterior end of the frame for pivoting about a left pivot axis. The exercise resistance source is connected to the frame. The frame, right pivot axis, and left pivot axis are configured and arranged such that the angle formed at the intersection of a first plane defined by the right pivot axis and the posterior end of the right half of the frame and a second plane defined by the left pivot axis and the posterior end of the left half of the frame is less than 90.degree..
