Which training zone is associated with 60-80% of maximum heart rate?

• A. The base training zone
• B. The top training zone
• C. The middle training zone
• D. The recovery zone

Answer: (C)

Training around 60-80% of your maximum heart rate sits in the middle, aerobic zone. This is a moderate-to-vigorous effort where you challenge your heart and lungs enough to trigger cardiovascular adaptations and improve endurance, while still allowing you to sustain the effort for a decent period. It's the range where the aerobic energy system is the main source of fuel, so you build efficiency and fitness without pushing into near-max fatigue. The recovery zone is lighter work (lower than this range) focused on recovery, and the base zone is generally lower still, aimed at building an aerobic foundation. The top zone would be higher than this range and used for shorter, high-intensity efforts.
