Answer:
The least important factor in determining the amount of overload needed to maintain or improve physical fitness varies depending on the individual, but it is generally agreed that the least important factor is the type of exercise performed. While different types of exercise can have different benefits and may be more or less effective for certain goals, the key factor in maintaining or improving physical fitness is the amount of overload placed on the body. This overload can be achieved through a variety of exercises and activities, as long as they are performed at an appropriate intensity and frequency to challenge the body and promote adaptation. Other factors, such as proper nutrition, rest, and recovery, may also play a role in maintaining or improving physical fitness.
