Heart rate zones, often known as HR zones, allow you to track your workout intensity. Based on how hard you work on your maximal heart rate, there are five heart rate zones.
This is the ideal moment to try target heart rate zones if you’ve ever been interested in heart rate zones. Heart rate monitoring provides information on the heart’s workload during exercise, which is useful information for customizing training to achieve particular fitness objectives.
Continue reading to find out more about running heart rate zones, including their definition and application to exercise and heart rate training.
WHAT ARE HEART RATE ZONES?
Training zones for heart rate are expressed as a percentage of your maximal heart rate. We shouldn’t work out for extended periods or frequently at or close to our maximal heart rates.
Heart rate zones enable you to exercise effectively and maintain a demanding level of fitness while assisting you in determining the intensity of your workout. Any time you increase the workload, elevation, speed, or other aspects of your workout, you are also raising the intensity and stress on your heart.
By tracking your heart rate throughout exercise, you can keep an eye on how hard you are exercising and modify your intensity as necessary.
FIVE HEART RATE ZONES
Heart rate zones range from zone 1 to zone 5, with five different zones.
Zone 1: 85% of the calories you expend are fat at this point. Compared to exercising at a higher intensity, you will burn less calories overall, but you will be able to maintain this zone for a longer period. At your current pace, you could easily carry on a discussion with someone.
Zone 2: Fat makes up about 65% of the calories you burn. In this zone, you can still carry on a casual discussion, although you might need to pause sometimes to catch your breath.
Zone 3: Fat makes up about 45% of the calories you burn. In this zone, speaking requires effort.
Zone 4: You’ve stopped using fat as fuel. This pace is not sustainable for longer than fifteen minutes. If it were necessary, you could talk now, but you really wouldn’t want to.
Zone 5: You have a limited amount of time to maintain this level of effort. It is not possible to talk.
HEART RATE TRAINING ZONES
This article explains the meaning of the five heart rate zones for exercise.
Heart rate zones may therefore be referred to by slightly different names and described in slightly different ways. It’s alright. Numerous gray zones exist. The basic line is that your body adjusts to meet your needs when your heart rate rises.
| Zone | Also known as | Intensity level | % of max heart rate | Fuel source |
|---|---|---|---|---|
| Zone 1 | Warm-up, recovery, easy. | Moderate-low. | 50% to 60% | Fat. |
| Zone 2 | Aerobic, endurance, base, light. | Moderate. | 60% to 70% | Fat. |
| Zone 3 | Tempo, threshold, cardio, moderate. | Moderate-high. | 70% to 80% | Fat, carbs and protein. |
| Zone 4 | Lactate threshold, redline, hard. | High. | 80% to 90% | Carbs and protein. |
| Zone 5 | Anaerobic, V02 max, peak, maximum. | Very high. | 90% to 100% | Carbs and protein. |
HEART RATE ZONE 1: 50–60% OF HRMAX
The zone of extremely low intensity is this. You will recover more quickly and be more prepared to work in the higher heart rate zones if you train at this intensity.
Choose an exercise that lets you easily manage your heart rate, like walking or cycling, to train at this intensity.
HEART RATE ZONE 2: 60–70% OF HRMAX
Heart rate zone 2 exercise seems easy, and you should be able to maintain this intensity for a considerable amount of time.
This is the zone that increases your overall endurance: your muscles will become more fit and your capillary density will rise as your body becomes more adept at oxidizing, or burning, fat.
Any fitness program must include training in heart rate zone 2. You will eventually reap the rewards if you persevere.
HEART RATE ZONE 3: 70–80% OF HRMAX
Enhancing cardiac and skeletal muscle blood circulation efficiency is particularly beneficial when exercising in heart rate zone 3. This is the area where your blood begins to accumulate that bothersome lactic acid.
Your efficiency will increase and moderate exertion will become simpler with training in this HR zone.
HEART RATE ZONE 4: 80–90% OF HRMAX
The hardest part of heart rate zone 4 is here. You’ll be working at an aerobic level and breathing heavily.
Training at this level of intensity will help you gain more speed and endurance. You’ll be able to tolerate higher blood levels of lactic acid for longer periods, and your body will become more adept at utilizing carbohydrates as fuel.
HEART RATE ZONE 5: 90–100% OF HRMAX
Your maximum exertion occurs in heart rate zone 5. Your respiratory system, heart, and blood vessels will all be operating at full capacity. Your blood will begin to accumulate lactic acid, and you won’t be able to maintain this intensity for a few minutes.
You most likely won’t need to train at this intensity if you’re just getting started or have only been exercising for a short while. For optimal performance, professional athletes should consider including interval training in their regimen.
HOW TO CALCULATE HEART RATE ZONES?
The two-step approach for calculating your running heart rate zones is provided below.
- Use an age-based formula: First, determine your estimated maximum heart rate. Ascertain your maximum heart rate (MHR), which varies from person to person, before computing your running heart rate zones. There are several approaches to MHR estimation. However, the most widely used approach is a straightforward age-based formula. MHR = 220 – (age) For instance, a 30-year-old’s estimated heart rate (HR) is 190 beats per minute (bpm).
- Conduct your own field HR max test: Determine the estimated heart rate zones in step two. Determine your precise running heart rate zones using percentage calculations once you know your expected maximum heart rate (HR). Target heart rate = MHR x (percentage of desired intensity) Examine the 30-year-old example’s heart rate zones in the following table.
| HEART RATE ZONE | FORMULA | TARGET HEART RATE |
|---|---|---|
| Zone 1: 50% to 60% | 50%: 190 bpm x 0.50 60%: 190 bpm x 0.60 | 95 to 114 bpm |
| Zone 2: 60% to 70% | 60%: 190 bpm x 0.60 70%: 190 bpm x 0.70 | 114 bpm to 133 bpm |
| Zone 3: 70% to 80% | 70%: 190 bpm x 0.70 80%: 190 bpm x 0.80 | 133 bpm to 152 bpm |
| Zone 4: 80% to 90% | 80%: 190 bpm x 0.80 90%: 190 bpm x 0.90 | 152 bpm to 171 bpm |
| Zone 5: 90% to 100% | 90%: 190 bpm x 0.90 100%: 190 bpm x 1 | 171 bpm to 190 bpm |
HOW CAN I CHECK MY HEART RATE OR PULSE?
With a target in hand, you may check that you’re in the zone by keeping an eye on your heart rate. Check your heart rate often while you work out. It’s really simple if you use a wearable activity tracker, but if not, you may find it manually as well:
- Take your pulse on the thumb and inside of your wrist.
- Press gently over the artery using the tips of your first two fingers, not your thumb.
- To find your beats per minute, count your pulse for 30 seconds and multiply the result by two.
HOW CAN I RAISE MY HEART RATE TO THE DESIRED LEVEL?
If you’re wondering whether you’re exercising too much when you work out, a straightforward method is using your target heart rate. This can help you optimize the benefits of each step, swing, and squat. Understanding your heart rate (or pulse) allows you to monitor your health and fitness level, even if you’re not a die-hard gym goer or professional athlete. Staying within your target heart rate zone ensures you’re working out effectively without overexerting yourself.
