When exercising, the heart rate range you should aim for is typically referred to as the target heart rate. This range is usually a percentage of your maximum heart rate and is considered the optimal level to achieve cardiovascular benefits.
To calculate your target heart rate, a common method is:
- Calculate maximum heart rate: 220 minus your age.
- Determine target heart rate zone: Aim for 50% to 85% of your maximum heart rate, depending on your fitness level and goals.
So, the correct answer is Target heart rate.
