Sets Training program designers must carefully control numbers of training phase sets during training sessions. When training activities have general applications, designers use one set per training session. When training activities are highly complicated motor skills, designers use three to six sets per training session. When training activities are uncomplicated motor skills and require physiological adaptations, designers use eight to twelve sets per training sessions. Final Stress Levels Training program designers must carefully control final training stress levels.
Athletes have physiological limits.
However, designers should never set limits. When athletes cannot perform training intervals at required stress levels for four consecutive training sessions, they demonstrate their final stress levels. When athletes cannot perform training intervals at required stress levels for four consecutive training sessions, they should return to their last successfully completed stress levels. Those stress levels are their final stress levels. Because athletes' psychological limits are lower than their physiological limits, wherever possible, athletes should not know the stress levels at which they are performing.
