What is a set? what is a repetition? how do sets and repetitions relate to one another in the context of a workout?

answer; i believe the answer is moderate level;

absolute strength refers to the maximum force exerted by a body irrespective of body size. relative strength on the other hand is the force exerted by a body in relation to muscle size or body weight.

so the answer is: c. absolute strength measures strength regardless of your body size, while relative strength measures strength adjusted for your weight.
