Which statement best describes muscle strength?

• A. Endurance
• B. The maximum force a muscle can exert in a single effort
• C. The ability to do many repetitions
• D. The proportion of body fat

Answer: (B)

Muscle strength refers to the maximum force a muscle or muscle group can produce in a single contraction. It’s about how hard you can press, pull, or lift in one effort, not how long you can keep going. Muscular endurance, by contrast, is the ability to perform many repetitions or sustain activity over time. Body fat percentage is a measure of body composition, not the amount of force a muscle can generate. So the description that fits best is the one stating the maximum force a muscle can exert in a single effort.
