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.
What are the various endurance tests for cardiorespiratory fitness?
Your cardiorespiratory fitness can be measured through some tests.

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.

The NHS has reignited the hybrid working debate – but WFH isn’t the health risk, this is
The latest NHS exercise guidance reinforces what we’ve been preaching for years: hitting that 150-minute weekly movement target isn’t necessarily a get-out-of-jail-free card. It states that prolonged sedentary time is independently harmful, even for those of us who diligently carve out time for the gym. Verbatim, it says ‘prolonged sitting is harmful, even in people who achieve the recommended levels of moderate to vigorous physical activity’.
Chief Medical Officer Professor Sir Chris Whitty has been especially vocal about how detrimental it could be, highlighting hybrid working as a potential health hazard. ‘Without wanting to exaggerate, I think it’s important people think through, for example, hybrid working means quite a lot of people could very easily do very little other than leave their homes, where previously people would be routinely going to work, and that often meant at least some physical [activity],’ he said at a briefing.
I understand his logic, but it’s pretty reductive. Working from home isn’t the villain here – working from one chair is.
When we label remote work as “bad for your health”, we risk throwing the baby out with the bath water. In reality, for many – certainly the whole of the Women’s Health office, but also my less-fitness-conscious sister and stepdad, plus my entire friendship group – working from home often means being more active. It means more time to fit in a lunchtime run, to get some steps in before work, or to run some errands on a quick break.
On the other hand, plenty of office workers are more sedentary than they are at home. They sit at a desk for nine hours straight before driving home, whether to be seen to work tirelessly in front of their manager, or simply because they’re pulled from pillar to post in an office setting. For those who do have an office commute, eliminating that often stressful period of the day allows for better sleep, and more time for the movement breaks we need to break up the dreaded sedentary time. Not to mention that many commutes are almost entirely sedentary on a train/tube/bus.
The potential problem, the advice suggests, is the lack of incidental movement – the walk to the train, the stroll to a meeting room, or heading out for lunch – that’s naturally baked into your day when you’re in the “official” office. Without a commute or a day in the office, the onus is on you to manufacture movement in.
Without sounding evangelical, I’ve made this a non-negotiable part of my day. On WFH days, I work out or walk every single morning before I log on, and walk again every evening, even if just a lap around the block. During the day, I have a personal rule: if I’m downstairs, I use the upstairs toilet (and vice versa). Sounds excessive, but it forces me to activate my muscles and add to my step count every few hours.
Beyond that, the options are endless if you’re intentional. Use a standing desk or put your laptop on a kitchen worktop during calls. Take every phone meeting on foot, pacing your hallway if necessary. Set a timer to stand up every 30 mins to stretch, grab a glass of water, or do a quick load of laundry.
We don’t need to return to the office to be healthy; we need to bring movement back into our homes. The goal: to stop being professional sitters.

A Strength Coach Says These Two Exercises Are All You Need to Build Stronger Shoulders
If you ask anyone on the gym floor how to grow a bigger set of shoulders, you’ll probably find that no two answers are the same. In between front raises, upright rows, machine presses and cable raises, shoulder day can quickly become a long list of exercises.
However, fitness creator and coach Eric Evans, also known on social media as Average to Jacked, thinks most lifters are overcomplicating things. He says that if he had to start from scratch after over a decade of training, he’d strip his shoulder workouts back to just two simple moves.
‘If I had to start over today, I’d build my shoulders with just two movements: a lateral raise and also a rear delt fly,’ he explains.
According to Evans, the reason for this isn’t because those exact exercises are magic, but because they work the correct movement pattern for the muscle.
‘Your body doesn’t know the name of the exercise you’re doing,’ he argues. ‘It really only knows the fundamental movement pattern you’re asking it to perform and also the amount of tension you’re placing on the muscle.’
So, you don’t have to perform cable lateral raises if your gym only has dumbbells, or use a reverse pec deck if you’d rather do bent-over rear delt flyes. As long as you’re training the same movement pattern and progressing the move with intensity or volume, you’ll achieve a similar result.
According to the coach, lateral raises deserve a place in your programme because they primarily target the side delts, helping create broader-looking shoulders and a more pronounced ‘V-taper’. Rear delt flyes train the back of the shoulders to create a rounder, more 3D physique.
‘I’m not including anything for the front delts, and that’s intentional,’ he says. ‘Your front delts are already heavily involved every time you do pressing exercises for your chest.’
For most lifters already bench pressing, incline pressing or overhead pressing regularly, he argues the side and rear delts are more likely to be the limiting factor.
‘I don’t think the front delts are what’s holding their shoulders back. I think it’s the side and rear delts,’ he adds.
He recommends focusing on controlling every rep, and avoiding using momentum to swing the weight. He also suggests working in the 8-15 rep range, adding reps until you reach the top of the range before increasing the load and repeating the process – also known as progressive overload.
‘You definitely don’t need to hit your shoulders from 10 different angles,’ he says. ‘You just need to consistently train these two movement patterns, push them hard and then gradually get stronger over time.’
The Bottom Line
Research suggests muscle growth is driven more by sufficient training volume, progressive overload and proximity to failure than by constantly changing exercises and programme hopping. In fact, that could hinder it. So if your shoulder workouts have become jam-packed with unnecessary variations, simplifying your approach may be exactly what helps you make more consistent progress in the long term.

80-year-old fitness icon Joan MacDonald reveals her simple exercise for a stronger, more stable core
Joan MacDonald didn’t enter a gym until she was 70. Really. Since then, the 80-year-old has transformed her health by losing three stone and building significant muscle, and now coaches other women through her training platform, Train With Joan, which she launched to help others boost their fitness at any age.
The premise of her app is simple: minimal-equipment workouts built around no-fuss, effective exercises that can be done anywhere. One ‘powerful core and stability exercise’ she swears by is alternating bodyweight clock taps. ‘This movement helps strengthen the muscles that keep you stable, balanced and moving well as you age,’ Joan explains.
Bodyweight clock taps benefits
Think they look too simple? That’s the point. Joan is adamant that ‘You don’t need complicated workouts to start getting stronger. Sometimes the most effective movements are the simple ones you do consistently.’
According to Joan, regularly performing bodyweight clock taps help:
- ‘Strengthen your core which supports your spine and reduces strain on your lower back.
- ‘Improve balance and coordination, helping you stay steady on your feet.
- ‘Increase hip stability, which supports your knees and joints.
- ‘Build functional strength for everyday movements like stepping, turning and reaching.
- ‘Help reduce fall risk by improving control and body awareness’
How to do bodyweight clock taps
Find a demo from Joan above, along with instructions for how to do them with proper form below.
- Stand on one leg with a slight bend in your supporting knee and brace your core.
- Keeping your hips level, reach your free foot forward to lightly tap the floor in front of you (12 o’clock), then return to the centre.
- Continue tapping to different “clock” positions—such as 3, 6 and 9 o’clock—maintaining your balance and control throughout.
- Complete all reps on one leg before switching sides.
Form tip: Move slowly and focus on staying stable. The goal is controlled movement, not how far you can reach.
How many reps and sets to do
Joan shares her advice, according to your fitness level.
- Beginners: ‘3 taps per leg x 8-10 reps’
- Intermediate: ‘3 taps per leg x 10-12 reps’
- Advanced: ‘3 taps per leg x 12-15 reps’
