Which of the following statements describe a key principle in training?a.Fitness levelb.High overloadc.Progressive overloadingd.Individual needs

The key principles in training are described by the statements "Progressive overloading" and "Individual needs".

Progressive overloading is a principle that involves gradually increasing the amount of stress placed upon the body during training. This can be done by increasing the weight lifted, the number of repetitions performed, or the intensity of the exercise. This principle is important because it helps to prevent plateaus in training and ensures that the body continues to adapt and improve.

Individual needs refers to the principle that each person has unique needs and abilities, and therefore, their training program should be tailored to meet these needs. This can involve adjusting the type of exercise, the intensity, the duration, and the frequency to suit the individual's goals, fitness level, and physical condition.

On the other hand, "Fitness level" and "High overload" are not principles of training. Fitness level is a measure of physical fitness, not a principle of training. High overload could potentially lead to injury or burnout, and is not a recommended approach to training.
