What range of heart rate corresponds to moderate-intensity activity?

Moderate-intensity activity is typically associated with a heart rate that falls within the range of 100 to 145 beats per minute (bpm). This range is indicative of exercise that elevates the heart rate to a level where one can still talk but might struggle to sing, often referred to as a "talk test." Activities such as brisk walking, light jogging, or cycling at a moderate pace usually elevate the heart rate within this range, allowing for improved cardiovascular fitness while still being manageable and sustainable for most individuals.

In contrast, lower heart rate ranges generally correspond to light-intensity activities where the physical exertion is minimal, making it easier for individuals to maintain a conversation without becoming winded. Higher ranges indicate vigorous-intensity activities, where the heart rate exceeds moderate levels and typically leads to increased effort and significant cardiovascular benefits but can be more challenging to sustain over time for many people.
