Limited information exists on the accuracy of RepWt at a fixed RTF as a predictor of 1RM performance. This study aimed to assess the accuracy of 3RM, 5RM, 7RM, and 10RM to estimate 1RM bench press performance. College men (n = 328) were randomly selected from a sample already tested for 1RM free-weight bench press. Subjects selected a RepWt to allow 3 to 10 RTF. Individual regression equations were produced for each group (3RM n = 78, 5RM n = 97, 7RM n = 87, and 10RM n = 66). Correlations were best for 3RM (r = 0.99) and least for 10RM (r = 0.92). A significantly greater number of subjects (χ2 = 12.23) were within 5% error when using 3RM (32%) than when using 10RM (15%). Fewer RTF with heavier RepWt appears to produce more accurate estimates of 1RM bench press in men of different experience and strength levels.
