What is Prilepin's chart?

Prilepin's chart is a guideline for structuring strength training regimens based on percentages of one's one-repetition maximum (1RM). It outlines the optimal number of repetitions and sets to perform within various intensity ranges to balance strength gains and recovery. The chart categorizes work into different percentage ranges, such as 55% to 65%, 70% to 80%, and onwards up to 90% plus. For each range, it specifies minimum and maximum repetitions and sets, as well as an ideal number of reps per set per week. This helps athletes and trainers structure their workouts to maximize strength while minimizing risk of injury or overtraining. 1
