The focus of this study is the frequency of training loads during a muscle hypertrophy-oriented workout. The current state of scientific research leads to the following questions: 1. What training frequency is optimal for the development of muscle mass in strength training beginners? 2. What training frequency is optimal for the development of muscle mass in experienced strength athletes? 3. Is there a difference in the development process of muscle hypertrophy depending on training frequency between beginners and experienced strength athletes? Based on the results of the study, the author provides recommendations for hypertrophy training in practice: load intensity, number of repetitions, training volume, rest duration, training frequency, training of intramuscular coordination, and strength training in youth.
