Apparatus (10) is disclosed including first and second supports (24) for supporting a stationary bicycle, with the supports (24) secured at adjustable longitudinal locations between first and second longitudinal rails (12). Cords (50) having grips (52, 54) on the opposite ends thereof are adjustably and slideably secured intermediate their ends at any location intermediate the ends of the longitudinal rails (12) by pivotable cam devices (60, 160) slideable and pivotable in upper channels of the rails (12). Additionally, the pivotable cam devices (60, 160) allow the lengths of the ends of the cords (50) to be adjusted relative to the rails (12). Thus, while pedaling and/or supported on the stationary bicycle, the user can exercise his upper body by stretching the cords (50) extending at various angles from locations in front, behind, and vertically below the user and with the desired tension depending upon the length of the cords (50) relative to the rails (12). In the preferred form, the pivotable cam devices (60, 160) include channel cams (68) rotatable within the upper channels of the rails (12) between locked and unlocked positions. The cord (50) is compressed in the upper channels in the locked position by a cord cam (62) integrally secured to the channel cam (68) and/or by a shoe (90) including a cut out for rotatable receipt of the channel cam (68).
