Which of the following is part of the "3 R's" of a post-workout routine?

The concept of the "3 R's" in a post-workout routine emphasizes essential elements that help the body recover effectively after physical activity. The correct answer, which includes Replenish, Repair, and Rest, highlights the necessary actions one should take post-exercise.

Replenish refers to replacing the fluids and electrolytes lost during exercise, which is crucial for hydration and overall recovery. Repair involves providing the body with the nutrients it needs to heal any muscle damage that occurred during the workout, often through protein intake, which is vital for muscle recovery. Finally, Rest signifies allowing the body ample time to heal and recover, which is critical for preventing injuries and promoting overall fitness gains.

The other options, while they do address aspects of post-workout recovery, do not align with the widely recognized structure of the "3 R's" framework. This makes option B the most accurate representation of what should be prioritized in a post-exercise routine.
