The principle of specificity is best illustrated by which of the following? (A) Lifting heavy weights to increase aerobic performance (B) Power walking to improve arm strength (C) Doing push-ups to reduce waistline size (D) Doing sit-ups to increase abdominal strength - HSC - SSCE Personal Development and Physical Education - Question 12 - 2001 - Paper 1

The principle of specificity states that training should be specific to the goals and muscle groups targeted. Among the options provided, the most accurate representation of this principle is option (D) 'Doing sit-ups to increase abdominal strength.' This is because sit-ups directly train the abdominal muscles, thereby enhancing strength in that specific area. In contrast, the other options do not appropriately align exercises with their intended outcomes.
