The conceptual constraints of traditional 1RM-testing make its regular use both impractical and unnecessary for the vast majority of athletes. In addition, small errors in estimating the 1RM value are of little practical relevance in real-world settings, where daily fluctuations in neuromuscular status naturally exceed such differences. Modern RT prescription should prioritize practicality, safety, and real-time monitoring of force application-criteria that submaximal, velocity-guided, and perceptual methods fulfill far more effectively than 1RM testing.
