The purpose of this study was to assess the change in strength resulting from resistance training with free weights and machine weights. College men (n = 429) who self-selected to train using free weights (FW, n = 173), seated horizontal press (SHP, n = 125), and supine vertical press (SVP, n = 131) were matched for FW 1-RM bench press and measured prior to and following resistance training 3 days/week for 12 weeks. Subjects who trained on machine weights were also measured for 1-RM on their specific training device. Following training, the FW group made a significantly greater gain in FW bench press than did the SHP or SVP groups. However, when measured on each specific training device, the SHP and SVP groups made greater gains than did the FW group. Thus, upper body strength gains appear to be specific to training device and are not equal across different devices.
