Differentiate aerobic and resistance training with a practical example.

• A. Aerobic improves endurance and resistance builds strength.
• B. Aerobic improves flexibility; resistance improves balance.
• C. Aerobic improves endurance (e.g., brisk walking); resistance builds strength (e.g., weight lifting).
• D. There is no difference between the two.

Answer: (C)

The main idea is that different training methods drive different adaptations: aerobic work targets cardiovascular endurance by relying on oxygen during sustained activity, while resistance work targets muscular strength by challenging muscles with higher resistance in short bursts. An example shows this well: brisk walking is a classic aerobic activity that you can sustain for a longer time, improving endurance and the heart–lung system. Weight lifting is a classic resistance activity that involves short, intense efforts to lift or push against resistance, leading to increased muscle strength and size. While both types improve overall fitness, their primary outcomes differ. Flexibility and balance are related but come from different training approaches (stretching for flexibility; balance can improve with various activities but isn’t the defining distinction between these two). There is a clear difference between the two in how the body adapts.
