During aerobic activities, monitoring heart rate is an essential aspect of understanding the intensity and effectiveness of the workout. The starting and ending heart rates can provide insight into your cardiovascular fitness and your body's response to exercise. Here’s a breakdown of how these heart rates can be evaluated:
Starting Heart Rate
- Definition: The starting heart rate, often referred to as the resting heart rate, is your heart rate before you begin any physical activity. It's a good baseline measure of your cardiovascular health.
- Measurement: To measure your resting heart rate, do so first thing in the morning before getting out of bed. You can use a heart rate monitor or check your pulse at your wrist or neck for 15 seconds and multiply by four for beats per minute (BPM).
- Normal Range: A typical resting heart rate for adults ranges from 60 to 100 beats per minute (BPM). Athletes may have a resting heart rate as low as 40 BPM due to higher cardiovascular fitness.
During Aerobic Activity

Intensity Zones: Aerobic exercises generally can be categorized into different intensity zones based on heart rate percentages:
- Light Intensity: 50-60% of maximum heart rate (MHR)
- Moderate Intensity: 60-70% of MHR
- Vigorous Intensity: 70-85% of MHR
To calculate your approximate MHR, use the formula: \[ \text{MHR} = 220 - \text{age} \]
Ending Heart Rate
- Definition: The ending heart rate is the heart rate measured immediately after stopping the aerobic activity. It can provide insight into your cardiovascular fitness and recovery capacity.
- Recovery Rate: After completing a workout, how quickly your heart rate returns to its resting rate is an important indicator of fitness. A faster decrease generally indicates better cardiovascular health.
- Measurement: Similar to the starting heart rate, you can measure your heart rate at the end of the workout immediately and then again after a few minutes.
- Normal Response: Generally, a decrease of 20-30 BPM in the first minute after exercise is considered a good indicator of aerobic fitness.
Summary
- Starting Heart Rate: Measure in the morning; normal range is 60-100 BPM.
- Intensity during Exercise: Varies (light, moderate, vigorous); target specific heart rate zones to meet fitness goals.
- Ending Heart Rate: Measure immediately after exercise; monitor recovery rate to assess cardiovascular fitness.
Always listen to your body and consult healthcare or fitness professionals if you're new to exercise or have health concerns.
