An exercise device for chin-ups which comprises a first support of a rigid material which has a first end and a second end and a mid point therebetween positionable in a horizontal orientation with its ends adjacent to the upper extent of a door opening on the first side thereof. The first support has vertical exterior apertures adjacent to the ends and vertical interior apertures between the exterior apertures and the midpoint. Further included is a second support of a rigid material with a lower horizontal extent positioned upon the upper sill of a door opening on the second side thereof opposite from the first side and with a vertical extent positionable against a vertical wall surface above the upper sill. The board has a first end and a second end a midpoint therebetween with horizontal apertures extending therethrough adjacent to its ends. The length of the second support is less than the length of the first support with the midpoints in a common vertical plane. Further included is a pair of contoured tubes of a rigid material. Each tube has an upper free end and a lower free end and an intermediate point therebetween. The upper free ends has apertures with connectors for coupling to the second support through its apertures. The lower free ends have apertures with connectors for coupling to the first support through its exterior apertures. The intermediate points have apertures with associated bolts and nuts for coupling to the board through its interior aperture.
