What percentage of 1-RM corresponds to 4 repetitions?

To determine the percentage of a one-repetition maximum (1-RM) that corresponds to performing four repetitions, it’s essential to reference established guidelines used in strength training and exercise physiology. According to these guidelines, the approximate percentage of 1-RM that can be lifted for a specific number of repetitions can be utilized to evaluate and quantify strength.

For four repetitions, research indicates that individuals are generally capable of lifting around 85% of their 1-RM. This percentage takes into account the ability of the muscle fibers to generate sufficient force and the fatigue that occurs during multiple repetitions. It reflects that as the number of repetitions increases, the maximum weight that can be lifted decreases, which is why higher percentages correspond to lower repetitions.

Therefore, stating that the percentage corresponding to four repetitions is 90% would not accurately reflect this relationship. Instead, 85% is the more accepted figure in exercise science, making it the correct choice in this context.
