Specificity applies to which aspect of training?

• A. Specific muscle groups
• B. Stress rest principle
• C. Repetition speed
• D. Recovery time

Answer: (A)

Specificity in training means your adaptations occur in the exact muscles and movements you stress. If your goal is to improve the strength, size, or endurance of a specific muscle group, you must train that group with exercises that load it directly, using a similar range of motion and contraction type. The body adapts at the tissues and neural pathways of the muscles you work, so targeting the muscle groups you want to improve yields the best results. The other concepts relate to different aspects of training—how rest and recovery enable adaptation and how the tempo of reps changes how the muscle is loaded—but they do not define which muscles are trained, which is what specificity is about.
