Answer:CExplanation:Whenever we lift weights, we are exerting force against the barbell. In physics, we measure force using Newton's Second Law of Motion via the equation f = ma, or put differently, force is equal to mass multiplied by acceleration. To generate more force, we must either increase mass or acceleration (or both).

C because lifting weights requires more so it builds more for heavier work
