What is the recommended intensity level for moderate aerobic exercise?

The recommended intensity level for moderate aerobic exercise falls within the range of 50-70% of maximum heart rate. This intensity is considered ideal for enhancing cardiovascular fitness while still allowing individuals to maintain the ability to converse during the activity. At this level, the body efficiently utilizes both fat and carbohydrates for energy, making it an effective choice for those looking to improve their aerobic capacity and overall fitness without overexerting themselves.

Engaging in exercise at this moderate intensity not only helps to improve heart and lung health but also supports weight management and general well-being. This range is supported by fitness guidelines and recommendations from health organizations that advocate for regular physical activity as part of a healthy lifestyle. In contrast, the other options represent higher intensity levels that are generally associated with vigorous exercise, which may not be suitable for everyone, especially those who are new to exercise or have certain health conditions.
