Answer:
Principle of overload : By exposing our body to higher level of strength, our body will developed the capability to handle it better in the future
Principle of progression : After being used to a specific limit, our body can surprise that limit and get used to higher level of limit, which make us stronger
Principle of specificity : A person should only train the body part that they needed (soccer player should focus on kicking power rather than punching power)

Overload refers to the amount of load or resistance, presenting a greater stress, or load, on the body than it is normally accustomed to in order to improve fitness.
The Overload Principle for Sports Fitness and Skills. The Overload Principle is a fundamental sports fitness exercise concept. For example, if a soccer player's goal is to promote upper body strength, he would remain to increase practice weight loads in upper body exercises until his goal was accomplished.
The principle of progression asserts that you should progress overload, which can be performed by applying FITT (frequency, intensity, time, and type) when your body accommodates to its present routine.
The specificity principle asserts that only targeted activities will promote specific health goals.
