Which of the following lists three principles of physical conditioning?

The correct answer includes balance, variety, and regularity, which are foundational principles of physical conditioning.

Balance refers to the importance of creating a well-rounded fitness program that includes different types of exercises targeting various fitness components, like strength, endurance, flexibility, and balance itself. This ensures that one area of fitness does not dominate at the expense of others, which can lead to imbalances and increased injury risk.

Variety is essential as it helps prevent boredom and keeps the training program stimulating and engaging. Incorporating a mix of activities and training modalities can enhance overall fitness and adaptive responses of the body, making the conditioning more effective and enjoyable.

Regularity emphasizes the importance of consistency in training for achieving and maintaining fitness goals. Consistent exercise not only yields physical improvements but also helps in establishing a routine that can lead to long-term behavioral changes towards health and fitness.

In contrast, the other options focus on aspects related to performance skills and workout intensity but do not encapsulate the holistic nature of physical conditioning principles as effectively as balance, variety, and regularity do.
