Which of the following is NOT a principle of training?

The principle of training refers to essential concepts that guide an effective exercise program. While specificity, overload, and progression are widely recognized principles that help in achieving fitness goals, consistency is more of a practice or a habit rather than a foundational principle of training.

Specificity involves tailoring training to meet specific goals. For instance, someone training for a marathon would focus on endurance activities specific to long-distance running. Overload refers to the necessity of increasing the intensity or volume of workouts to continue making progress, pushing the body beyond its usual limits. Progression suggests that as individuals adapt to training, they must gradually increase the demands placed on their bodies to continue improving.

Consistency, while critical for achieving results and maintaining fitness levels over time, does not constitute a training principle. Rather, it emphasizes the regularity with which one engages in training efforts. It plays an important role in the long-term success of a fitness program but lacks the structured basis found in the other three principles.
