Question

5/15 target heart rate zone is your maximum heart rate where you want your resting heart rate what your recovery heart rate should reach where you want your exercise heart rate to receive fitness benefit

Explanation:

The target heart rate zone is the range of heart rate during exercise that helps achieve fitness benefits. Let's analyze each option:

• "your maximum heart rate" is a single value, not a zone.
• "where you want your resting heart rate" is incorrect as resting heart rate is when at rest, not related to exercise zone.
• "what your recovery heart rate should reach" is about recovery, not exercise target zone.
• "where you want your exercise heart rate to receive fitness benefit" matches the definition of target heart rate zone.

Answer:

where you want your exercise heart rate to receive fitness benefit
