Limited information appears available on the use of submaximal fixed loads and repetitions as predictors of 1RM performance in women. PURPOSE: To assess the predictive accuracy of the 3-4RM, 5-6RM, and 7-10RM to estimate 1RM bench press performance in untrained women. METHODS: 222 untrained college women were tested for 1RM free-weight bench press. Following 2 days of recovery, all subjects self-selected a RepWt that would allow between 3 and 10 repetitions to fatigue (RTF). RESULTS: Correlations and standard errors of estimate were lowest for the 3-4RM group (r = 0.86, SEE = 2.5 kg, CV% = 7.8%) and highest for 7-10RM (r = 0.90, SEE = 4.1 kg, CV% = 12.9%). CONCLUSIONS: A RepWt that produces between 3 and 10 RTF appears able to produce an estimated 1RM bench press in untrained women with an average error of 1% (10%).
