Why is tracking your heart rate so important?

Cardio can be challenging as it is based in effort rather than actual output. Sure you can track your progress with a burpee challenge (how many burpees can you do in 2 minutes) or if you run then distance but who wants to do this every time? Also this changes each day with how much sleep you have had, when you last ate, let alone running isn’t suitable for everyone. Monitoring your heart rate when you’re exercising will give you accurate tracking so that you can see in real time how you are doing and ensure you are staying in your optimal zones.

Is going to fail a sign of your best workout?

Starting off… the answer is NO. There are benefits to all the different types of workouts and a good combination will serve you best and ensure you get the most gains by allowing your body to challenge itself, recover and also avoid injuries which can be incredibly defeating when you feel like you are on a roll. Everyone has a different combination that will be best for them and this will depend on your goals, how you feel on the day and also what else you have going on in your life. If you are doing our 6 week challenge you will have a consult with our Wellness consultant/Personal Trainer to ensure that your workouts are planned to get you the best results that are maintainable.

Varying Your Workout

Which zone should you work out in? It is best to vary your workouts for length and intensity and allow a recovery day between days of intense exercise in the aerobic, anaerobic, and red-line zone. Our HIIT classes will have different exercises with different combinations of timing for this very reason.

Cardiovascular exercise relies on frequency, intensity, and duration to be effective. You know how often you exercise and for how long, but you need to know your heart rate to judge your intensity. Learn more about the effects of each of five heart rate zones and how to use them in your cardio workouts

Heart Rate Zones Based on MHR 

Generally your MHR was calculated as 220 – your age but a more accurate (if slightly more complicated) formula is 206.9 – (0.67 x age). You can use heart rate zone training to gear your workout to the correct intensity. Your maximum heart rate is as fast as your heart can beat. This varies for each person, but age is generally used as a guide for what your maximum heart rate is likely to be. A more individualised number can be provided by testing by an athletic trainer, or at some medical facilities. You can use an age-based heart rate chart to see your maximum heart rate and also find your target heart rates based on percentages of the maximum heart rate.

Heart Rate Zones

Healthy Heart Rate Zone: 50-60% MHR

Fitness Heart Rate Zone: 60-70% MHR

Aerobic Heart Rate Zone: 70-80% MHR

Anaerobic Heart Rate Zone: 80-90% MHR

Red-Line Zone: 90-100% MHR

Using Heart Rate Zones in Your Workouts

You can get different fitness benefits by exercising in different heart rate (HR) zones. These five exercise zones are based on the percentage ranges of maximum heart rate. In each zone, you will feel a different level of exertion and your body will be burning a different percentage of carbohydrate, protein, and fat.

Healthy Heart Zone

The healthy heart rate zone is 50 percent to 60 percent of your maximum heart rate. This is an easy and comfortable zone to exercise in. It’s considered to be the lower end of the moderate intensity zone. You will be able to carry on a full conversation in this zone, although you may be breathing a little heavier than usual.

Your workout in this zone is less intense and won’t give the most cardiorespiratory training benefits. But studies have shown that it works to help decrease body fat, blood pressure, and cholesterol.

In this zone, the body derives its energy by burning 10 percent carbohydrates, 5 percent protein, and 85 percent fat.

Walkers are often in this zone unless they press themselves to walk faster. If you exercise in higher heart rate zones, taking a healthy walk in this zone is a good way to enjoy an easy recovery day while still being active.

Fitness Heart Rate Zone

The fitness heart rate zone is from 60 percent to 70 percent of your maximum heart rate. This is the higher end of the moderate-intensity exercise zone. You will be breathing heavier but will still be able to speak in short sentences.

You burn more calories per minute than in the healthy heart zone because the exercise is a little more intense. You are going faster and therefore covering more distance. The calories you burn depend on the distance you cover and your weight more than any other factors. In this zone, your body fuels itself with 85 percent fat, 5 percent protein, and 10 percent carbohydrate.

You get the same health benefits and fat-burning benefits as the healthy heart zone. An example of a workout in this zone is a brisk walking workout.

Aerobic Heart Rate Zone

The aerobic heart rate zone is from 70 percent to 80 percent of your maximum heart rate. You are now in the vigorous-intensity zone. You will be breathing very hard and able only to speak in short phrases.

This is the zone to aim for when training for endurance. It spurs your body to improve your circulatory system by building new blood vessels and increases your heart and lung capacity. Aiming for 20 to 60 minutes in this zone is believed to give the best fitness training benefits.

In the aerobic zone, you burn 50 percent of your calories from fat, 50 percent from carbohydrate, and less than 1 percent from protein. With the increase in intensity, you burn more calories in the same amount of time, as you are covering more distance in that same time. The calories you burn depend most on distance and your weight. If you go farther in the same amount of time, you burn more calories per minute.

Anaerobic Zone (Threshold Zone)

The anaerobic heart rate zone is 80 percent to 90 percent of your maximum heart rate. You will be unable to speak except a single, gasped word at a time.

This intense exercise will improve the amount of oxygen you can consume—your VO2 maximum. This exertion level takes you to the limit where your body begins to produce lactic acid. Runners, cyclists, and racewalkers use this zone to build their ability to go even faster.

Workouts in this heart rate zone should be in the 10-20 minute range or part of an interval training workout.

You burn more calories per minute than with the lower heart rate workouts, as you are covering more distance per minute. The body burns 85 percent carbohydrates, 15 percent fat and less than 1 percent protein in this zone.

Red-Line Zone

The top zone is from 90 percent to 100 percent of your maximum heart rate. You can’t go any higher, and most people can’t stay in this zone for more than a few minutes. You will be unable to speak except for gasping single words.

This zone should only be used for short bursts during interval training, where you work intensely for a minute and then drop back down to a lower intensity for several minutes, and repeat.

While you burn lots of calories per minute in this zone, 90 percent of them are carbohydrates, 10 percent fats, and less than 1 percent protein.

You should consult with your doctor to ensure you can work out at such a high heart rate safely.
