Special exercises are routinely used to monitor strength qualities in weightlifting when recent maximal snatch and clean-and-jerk performances are unavailable. This study developed and internally assessed an exploratory model for estimating a training total from special-exercise strength measures while accounting for sex and body mass. Retrospective records from 27 senior high-performance weightlifters (14 men and 13 women) were analyzed. The training total was calculated from the most recent maximal snatch and clean-and-jerk records obtained within an approximately two-week precompetition window. Simple and partial correlations, hierarchical linear regression, collinearity diagnostics, residual analyses, and leave-one-out cross-validation were examined. Sex and body mass explained 94.3% of the variance. Adding front squat and strict military press increased explained variance to 97.9% and reduced the standard error of estimate from 16.58 to 10.52 kg. The internally assessed RMSE was 11.47 kg and MAE was 9.25 kg; however, front squat showed substantial collinearity. The model may provide a provisional monitoring reference under comparable conditions, but the small sample, predictor selection within the same dataset, collinearity, and absence of external validation preclude treating it as a confirmed predictive equation.
