Final answer:
Linear periodization is a training method where intensity gradually increases and volume decreases over time, which is used to progress in weightlifting and other forms of training. The correct answer is option (A)
Step-by-step explanation:
The correct answer to the question is A) Linear periodization, which is a traditional method of program design aiming to gradually increase the intensity of the training load, while simultaneously decreasing volume over a set period of time. This contrasts with nonlinear periodization, where the intensity and volume are varied in a non-systematic way. An example of linear periodization could involve a weightlifter increasing the weight lifted over time while decreasing the number of repetitions to ensure ongoing progression.
