What does the principle of progression in training entail?

The principle of progression in training emphasizes the importance of gradually increasing the volume and intensity of workouts to facilitate continued improvement in performance and fitness levels. This approach helps the body adapt to the increasing demands placed on it, promoting enhancements in strength, endurance, and overall physical capacity. By systematically advancing the challenges in training, such as adding weight, increasing repetitions, or enhancing workout duration, individuals can effectively stimulate physiological adaptations that lead to improved athletic performance and reduce the risk of hitting a plateau.

On the other hand, options that suggest decreasing workout volume or sticking to a fixed routine would not align with the principle of progression, as these approaches do not challenge the body or allow for advancement in fitness. Additionally, simply increasing the variety of exercises each week, while it may prevent boredom or promote overall balance, does not inherently focus on the gradual advancement necessary for adaptation, which is central to the progression principle.
