Controversy exists concerning the potential of free weights (FW) and machine weights (MW) for developing upper-body strength development. The purpose of this study was to compare upper-body strength gain between FW and MW resistance training. College men self-selected to training using FW bench press (n = 85) or MW vertical press machine (n = 32). The two groups were not significantly different in initial body mass, fat-free mass (FFM), or method-specific 1RM strength. Each group performed similar training programs 3 days/week for 12 weeks before being retested. FW (18 ? 11%) group increased specific strength more than MW (10 ? 9%). FFM increased significant in both groups (~1%) with a significant correlation with strength gain only for FW (r =0.29) compared to MW (r = 0.16). The outcome suggests that similar training programs on different modes of resistance will result in greater strength gains in men from FW training.
