Which of the following statements about Aqua Fitness is true?

Aqua Fitness workouts are designed to be versatile and accommodating, making them suitable for individuals of varying fitness levels. This adaptability allows instructors to modify exercises to meet the needs of beginners, intermediate, and advanced participants. For instance, the intensity of movements can be increased or decreased, and the depth of water can be adjusted depending on the individual's comfort and skill level. This customization is one of the key benefits of Aqua Fitness, as it enables a wide range of participants to engage with the workouts safely and effectively.

The other statements, on the other hand, misrepresent Aqua Fitness. It is not exclusively for competitive swimmers, as anyone can participate regardless of their swimming ability. Additionally, Aqua Fitness can indeed promote cardiovascular health through effective aerobic exercises that are low-impact due to the buoyancy of water. Finally, while some Aqua Fitness classes may benefit from instructors having specialized training, not every participant requires specialized training to join and benefit from these classes.
