Abstract: Weight bench apparatus including a pair of spaced vertically extending barbell support arms, a bench seat positioned between the support arms having a back portion which is constructed to pivot between a plurality of incline positions, and a horizontally extending seat back support bar which is constructed to extend between and connect with the barbell support arms in different vertically spaced positions to selectively support the back portion in a plurality of incline positions. The support bar is constructed to enable the length thereof to be adjusted to vary the distance between the barbell support arms. Preferably, the seat back support bar includes a hollow outer bar member, an inner bar member which slidably fits in the outer bar member in telescoping relation therewith, and a locking member for locking the inner and outer bars together in desired relative positions.
