The correct answer to this option is the following.
Although there are no options attached we can say the following.
It is correct to say that effective fitness plans focus on principles of specificity, overload, and progression. Taking into consideration these principles, a great example of planning a workout would be this.
The principle of specificity establishes that a person or an athlete has to train the specific parts that it needs to develop. For instance, if you are a baseball pitcher, you need specific work for your arm and wrist.
The principle of progression establishes that the body can get past the originally established limits, allowing us to lift higher weights to be more strong.
The principle of overload establishes that the human body will increase its capacity to respond to higher weights or intensity by exposing it to different levels of intensity or strength.
So a great exercise plan must contain a good evaluation of the individual's capacity to perform any kind of exercise. Then, a good nutrition plan to maximize your workout. Then, the plan has to consider the days, frequency, and hours a day for your exercise. What follows is a daily routine with the specific set of exercises needed in cardio or lifting weights.
It is important to be supervised by your fitness coach so he/she can properly instruct you and make corrections.
