What advice would you give to someone who is just beginning to be physically active?

Start off with 15 minutes a day, and work your way up as the weeks progress.

Explanation:

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.
