Load progression in training includes various aspects. Which aspect is NOT included?

Load progression in training primarily focuses on methods to enhance a trainee's strength and muscular development over time. This typically includes increasing the overall volume of work performed (more sets or repetitions), increasing the weight lifted (load), and potentially increasing the frequency of training sessions (how often a specific muscle group is trained per week).

Volume increase refers to the total amount of work done in a training session or over a specific period, which is crucial for stimulating growth and strength gains. Load increase directly corresponds to the amount of weight being used in training, which is fundamental for challenging the muscles as they adapt. Frequency increase denotes how often workouts are performed, which can also contribute to ongoing improvements in performance and endurance.

In contrast, volume reduction does not align with the concept of load progression as it implies a decrease in training overall workload. During a process of advancement in training, reducing volume would not lead to progressive overload, which is central to making gains in bodybuilding and strength training. Thus, recognizing that progression involves enhancing load through the growth of volume, weight, and frequency, volume reduction stands out as a method not included in the principles of load progression.
