Abstract: An exercise device for performing a variety of exercises in both doorway-mounted and floor-mounted configurations is described. The device includes a horizontal bar configured for engagement with a doorframe, a pair of support arms, each having one end attached to the horizontal bar and the other end extending through a doorway, and a pivot bar connected between the support arms. The device further includes a pair of pivot arms configured to be rotated about the pivot bar at their first ends so as to be oriented and secured in a plurality of different angular positions relative to the support arms, and a pull-up bar including at least one grip handle configured to be rotated about the pivot arms at their second ends so as to be oriented and secured in a plurality of different angular positions relative to the pivot arms.
