What is the primary purpose of target heart rate in training?

• A. Increase strength only
• B. Improve flexibility
• C. Prevent overtraining and undertraining
• D. Decrease resting heart rate during sleep

Answer: (C)

Target heart rate is used to keep workout effort in a level that provides the right stimulus for cardiovascular fitness while allowing adequate recovery. By training in a prescribed heart-rate zone, you ensure the work is challenging enough to improve endurance without being so hard that recovery suffers, which helps prevent both undertraining (not enough stimulus) and overtraining (too much stress without rest). It isn’t primarily about increasing strength, which comes more from resistance work, nor is it about flexibility. While consistent endurance training can gradually lower resting heart rate, that is a longer-term adaptation, not the immediate reason for using target heart rate during workouts.
