Answer: The starting skill level of the physical activities included in a personal fitness program should be determined from other individuals' fitness programs.
Step-by-step explanation: When developing a personal fitness program, it is important to consider personal factors such as age, health concerns, and preferences (Statement B). It is also crucial to implement strategies that will help maintain the program and ensure a successful start (Statement A). Additionally, the FITT principle, which stands for Frequency, Intensity, Time, and Type, is commonly used as a guideline for structuring a personal fitness program (Statement D).
Statement C is not true because determining the starting skill level for physical activities in a personal fitness program should be based on an individual's own capabilities and fitness level, rather than relying on other individuals' fitness programs. Each person's fitness journey is unique, and it is important to tailor the program to their specific needs and abilities.
