However, it is recommended to do 5 sets, 3 reps apiece, of power cleans, rather than 3 sets of 5. The reason lies in the nature of this specific exercise and its technical nature. Fatigue is not the primary goal during the clean, rapid force generation and technical accuracy is. Because the exercise is the most mechanically difficult exercise to perform and it involves a tremendously large # of muscle groups, even moderate fatigue of the supporting musculature can have a prominently adverse effect on the trainee's ability to perform the exercise at all, let alone correctly.
Lower rep sets are more appropriate once the trainee is able to perform the exercise with a base level of competence. Unlike most standard exercises in bodybuilding and strength training, fatigue is NOT the goal. Exact technical accuracy in exercise execution is far more important and fatigue is neither beneficial or even appropriate. Sets with lower repetitions, such as 1, 2, and 3 reps per set, are more successful at ensuring the lift is worked properly and that force generation is even and consistent.
