Want to increase your stamina? Work on your cardiorespiratory fitness and endurance!

Cardiorespiratory fitness refers to how well your body does while performing a physical task. A healthy diet, weight control and interval training are great ways to improve this.

An increase in stamina, low chances of heart disease and control over high blood pressure are all benefits of cardiorespiratory fitness. Cardiorespiratory fitness, also known as cardiorespiratory endurance, cardiovascular fitness, and cardiovascular endurance, improves oxygen levels in the lungs and heart when we are doing anything that involves physical exertion.

Cardiorespiratory fitness refers to how well your body can perform when you are exercising. If your cardiorespiratory fitness is on point, you can endure long, physical exercise without getting tired. Read on to learn more about cardiorespiratory fitness, the exercises that can help you improve it, as well as the risks involved.

What is cardiorespiratory fitness?

Cardiorespiratory fitness (CRF) refers to the ability of the cardiovascular and respiratory systems to deliver oxygen during prolonged physical activities. “It is an important sign for overall health and heart function,” explains cardiologist Dr Chirag D.

According to research published in Nutrition in the Prevention and Treatment of Abdominal Obesity, cardiorespiratory fitness can be determined by gender, age and genetics, as well as, the relationship between your health and physical activity. Strong CRF allows you to perform daily activities with more ease, reducing fatigue during tasks like climbing stairs or carrying groceries. It also helps you recover faster from exercise, allowing you to get back to your workout routine sooner.

1. VO2 Max Test

This test measures the maximal uptake of oxygen in a high-intensity exercise. In this exercise, you get on a treadmill or a bike and increase your intensity every few minutes, until you are exhausted. This method is touted to be the most accurate one, states this research, published by the University of Virginia.

2. 6-Minute Walk Test

This test evaluates sub-maximally distance covered within six minutes. This test is low risk and is useful in assessing adults who have love cardiorespiratory fitness, states this study, published in Pulmonology.

3. Treadmill Stress Test

This test monitors heart rate during increasing intensity levels on a treadmill. This test is usually done in a lab, where electrodes are put on the patient’s chest, and these are then connected to an ECG machine. This makes a record of all heart activity, including blood pressure and heart rate, states this study, published by the National Institute of Health.

What are the causes of low cardiorespiratory fitness?

Various causes are associated with low respiratory fitness levels. Some of these are as follows:

  • Sedentary lifestyle: No regular exercise and sedentary desk jobs can lead to cardiorespiratory fitness levels dropping. No exercise often leads to fatty material in your arteries. This can cause serious problems, including a heart attack. Exercise is beneficial for cardiovascular health, states this study, published in Frontiers in Cardiovascular Medicine.
  • Chronic diseases: Illnesses like heart attack, diabetic condition, and lung problems can also lead to a drop in cardiorespiratory fitness. This disease can also cause pain and fatigue.
  • Obesity: The burden of excessive body weight on the heart and lungs can lower cardiorespiratory fitness levels. It may also lead to cardiovascular diseases and needs to be worked on at once, reports a study, published in the Journal of Obesity.
  •  Aging: Gradual deterioration of body strength and muscle mass over time. A study, published in the Archives of Internal Medicine, states that cardiorespiratory fitness levels decrease with age.

1. Regular aerobic exercise

Regular exercise such as walking, running, and cycling improves the performance of both the heart and lungs. A study, published in Research Quarterly for Exercise and Sport, states that adults should do 150 minutes of moderate-intensity or 60 minutes of vigorous-intensity physical activity per week, as recommended by the American College of Sports Medicine (ACSM) and the American Heart Association (AHA).

2. Interval training

Endurance can be enhanced through fluctuating intensities between highs and lows. High-intensity interval training is a form of exercise where you have short periods of intense and explosive movements, followed by low-intensity exercise or even rest. This helps control obesity and increase cardiorespiratory fitness levels, states this study, published in Frontiers in Public Health.

3. Healthy diet

Nutrient-rich foods support overall physical health and energy levels. A study, published in Nutrients, observed the impact of a healthy diet on a group of Korean adults from 19-64 years. The VO2 Max test was used to determine the cardiorespiratory fitness levels. It was seen that adults, in the age group of 19-34 years, reported high CRF levels.

4. Consistency

Regular, sustained effort is crucial for long-term improvements. Make sure that you continue to do the above-mentioned things regularly to see a change.

Cardiorespiratory activities

You can try some cardio-respiratory activities that help elevate your breathing and heart rate for an extended period of time, suggests fitness expert and Fit India Ambassador Wanitha Ashok.

  • Brisk walking
  • Running
  • Jogging
  • Cycling
  • Swimming
  • Aerobics
  • Dance
  • Zumba
  • Jumping rope
  • Stair climbing
  • Treadmill
  • Stationary cycling
  • Cross trainer
  • Circuit training
  • High-intensity interval training (HIIT)
  • Kickboxing

What to keep in mind while doing CRF exercises?

Make sure to keep these things in mind when you practice cardiorespiratory fitness:

  • One should start slow and gradually build the workout in terms of duration and intensity.
  • You should not push yourself and listen to your body.
  • Hydration before, during and after the cardio respiratory exercises is advised to replace the list water in the form of sweat and to prevent giddiness and nausea.
  • It’s not advisable to do cardio respiratory exercises in the hot Sun, the best time to workout is early morning or evenings. In cold temperatures it’s advisable to be dressed in layers.

What are the risk factors related to cardiorespiratory fitness?

Low cardiorespiratory fitness, linked to an inactive lifestyle, weakens your body’s ability to use oxygen during exercise. Age, genetics, and certain medical conditions can also contribute. Additionally, high lipid values, high blood pressure, higher heart rates, higher waist circumference and higher body fat percentages can affect cardiorespiratory fitness levels, states this study, published in Scientific Reports.

Regular physical activity is key to improving your CRF. Even small increases in activity can significantly benefit your heart, lungs, and overall health.

Unlikely habit helped new parents shed 50 kilos

Unlikely habit helped new parents shed 50 kilos

Books are getting Australians into the gym and keeping them there longer, and the benefits of this emerging health trend aren’t just physical – they’re mental too.

Listening to audiobooks and podcasts helped Yvonne Kong, 41, and her husband get back into fitness after becoming parents and lose a combined 50 kilos.

It also helped them broaden their minds and carve out a bit of “me time” in our busy modern world.

Audiobooks and podcasts have given Aussies the chance to turn exercise into a vehicle for learning, training their minds and bodies simultaneously. Some are even taking their e-readers and paperbacks to the gym (more on that later).

“Listening to a story while working out actually helped me stay motivated and more consistent,” Kong told nine.com.au.

Like many Aussies, she used to dread hitting the treadmill and constantly found herself counting down the minutes until her session was over.

That changed when she hit play on a true-crime podcast during a workout.

Kong got so caught up in the story she forgot about the timer on her treadmill until her workout was over.

“I did an hour treadmill course and actually finished it without noticing,” she said.

Since then, she’s found herself looking forward to exercising because it gives her an hour of dedicated listening time.

Her husband does the same while running; he took up listening to audiobooks because it motivated him to run longer and more often so he could get through the story.

The benefits of reading/listening while exercising

About one in three Aussies now listen to audiobooks when they exercise, according to data from Audible.

More than a third of them exercise for longer because of it, one quarter work out more often, and half experience better mood during exercise.

Data released exclusively to nine.com.au revealed both men and women reported these positive experiences at an almost identical rate, despite often having different workout routines and attitudes towards exercise.

Audiobooks are particularly popular with runners, more than a third of whom say they feel more focused on their run while listening.

Personal trainer Ben Lucas is one of them; he started listening while running to make time pass quickly and train his mind as well as his body.

“You’re out there anyway, so you may as well be learning something valuable while you do it,” he told nine.com.au.

What the experts think

Mindfulness expert Luke McLeod told nine.com.au there has even been some research into how exercise increases blood flow to the brain, which helps information retention.

Lucas devours business and personal development audiobooks like Atomic Habits by James Clear while working out, a trend which has become known as ‘personal development/PD stacking’.

The goal is to “double-up of some type of personal development like listening to an e-book, which works out the mind, while also working out the body,” McLeod said.

‘PD stacking’ is the new health optimisation trend, according to Luke McLeod. Luke McLeod

It’s all about optimising time in our busy world, which is particularly appealing to Aussies who are time-poor; like new parents trying to juggle work and a baby.

“When I’m with [my daughter], I’m trying to be present for her, so I’m not going to be listening to podcasts or anything,” Kong said.

McLeod agreed that reading or listening while working out can be a great form of self-care for some Aussies.

The only pitfall is that not every workout is suited to it.

It’s hard to keep up with an audiobook or podcast if you’re trying to count reps while strength training, and there’s no way to read an e-book on a rowing machine.

“I find podcasts and audiobooks work best during longer, slower cardio sessions,” Lucas said.

“Whether it’s an easy run, walk, or long ride, you can relax into the session, tune out a little, and focus on what you’re listening to while still getting the work done.”

He also warned Aussies to stay aware of their surroundings and hazards like traffic, cyclists, other pedestrians, or uneven paths if they listen while exercising outdoors.

McLeod added that stacking habits like exercise and reading isn’t worth it if one interrupts the other.

Road testing reading at the gym

I’ve been in and out of the gym a lot over the last decade, jumping from strength training, to reformer Pilates, and other programs in between.

But my favourite way to exercise is to hop on a treadmill with my Kindle.

I rest it on the console, set a slight incline and a moderate speed and lose myself for an hour. No workout has ever felt faster or easier.

Reporter Maddison Skipper reads a Kindle while walking on the treadmill at her local gym.

The pros: Focusing on what I’m reading takes my mind off the clock and get through an hour of cardio without getting bored or losing motivation.

Reading at the gym also helps me stay consistent because it’s one of the few places I can just switch off and focus on my book without interruptions, so I want to keep coming back.

That hour of dedicated reading time has also been great for my mental health because it forces me to slow down and focus on something completely removed from any stress in my own life.

The cons: It did take a few sessions to get used to reading while moving, but raising the brightness on my Kindle and setting it to a larger font really helped.

Those who prefer to listen don’t have to worry about any of that though; just download an audiobook and you’re good to go.

I also invested in a pair of noise-cancelling headphones to muffle the dance music that plays over my gym’s loudspeakers, which made it much easier to focus.

Now the only downside to reading at the gym that I sometimes hit a slump after I finish a really good book because I don’t want to hit the gym again until I find something new to read.

The verdict: It’s not for everyone, but I have found that reading at the gym has been the best way for me to stay motivated and consistent.

I feel good about taking the time to work on both my body and my mind a few times a week, and I’ve been able to check some amazing books off my ‘to be read’ list while working out.

Audiobooks make it even easier for Aussies who want to exercise without the hassle of a physical book or e-reader, or who have different accessibility needs.

The Best Fitness Trackers for Your Lifestyle, Workouts, and Goals

Like every piece of gear you wear on your body day in and day out, fitness trackers are incredibly personal. The right tracker for you should be comfortable, accurate, and tailored to your lifestyle, including your preferred workouts and health goals. Do you bike, row, or strength train? Do you run on trails for hours at a time, or do you just want a reminder to stand up every hour? Do you want to wear it on your wrist or your finger, or tuck it into your sports bra?

No matter what your needs are, there’s never been a better time to find a powerful, sophisticated tool to help optimize your workouts or jump-start your routine. We test dozens of fitness trackers every year while running, climbing, hiking, or just doing workout videos on our iPads at night, to bring you these picks.

Our top choice for most people is the Garmin Vivoactive 6 ($300), which works well with Android and iOS, but we also vouch for the latest Oura Ring 5 ($399) and the budget-friendly Google Fitbit Air ($100). For more wearables, check out our guides to the Best Smartwatches, Best Smart Rings, and Best Sleep Trackers.

Best Fitness Tracker Overall

Garmin makes some of the most accurate fitness trackers on the market, and the Vivoactive 6 is the best midrange option for most people. It strikes a solid balance between smartwatch features and fitness tracking, with support for both iPhone and Android users.

Why WIRED recommends: The Vivoactive 6 is accurate, comfortable, and packed with useful wellness features without feeling overwhelming. It uses Garmin’s proprietary algorithms to power features like Morning Report and Body Battery, which provide daily insights into your sleep, recovery, and readiness. It also has built-in satellite connectivity and GPS, so you can track outdoor workouts without bringing your phone along. There’s also incident detection, which alerts emergency contacts if it detects a serious fall.

Garmin’s biggest advantage remains its free Connect platform, which enables health and fitness tracking without requiring a subscription. The company also continues to add new software features through regular updates without putting them behind a paywall.

The trade-offs: Garmin launched Connect+, a $70-per-year subscription with extras like live tracking and access to Garmin’s AI-powered Active Intelligence. Former editor Adrienne So doesn’t think most people need it, but it’s worth noting if you’re looking for a completely subscription-free experience. The Vivoactive 6 may also feel like overkill for casual users who only want basic activity and sleep tracking.
