What is the target heart rate zone for moderate-intensity exercise?

The target heart rate zone for moderate-intensity exercise is typically defined as 50-70% of an individual's maximum heart rate. This range is considered optimal for improving cardiovascular fitness and overall health without overexertion, making it accessible for most participants engaging in aerobic activities.

During moderate-intensity exercise, individuals can still hold a conversation, which is a useful marker for gauging intensity. This level of exertion allows for effective calorie burning and improves aerobic capacity while reducing the risk of injury or excessive fatigue.

Lower percentages, such as 30-50% of maximum heart rate, would characterize light-intensity exercise, suitable for warming up or cooling down, but not sufficient for moderate physical conditioning. Conversely, higher percentages of 70-85% or 90-100% of maximum heart rate fall into vigorous activity levels, which are more taxing and require higher fitness levels to sustain safely. Thus, the 50-70% range is ideal for achieving the benefits associated with moderate-intensity exercise.
