One of the first questions many people ask when starting to exercise is how often they should do cardio. Some believe they need to work out every day to see results, while others worry that exercising too much could leave them exhausted or increase the risk of injury.
The truth is that there isn’t a single perfect answer. The right amount of cardio depends on your current fitness, your goals and how active you already are throughout the rest of the week. For most beginners, finding a routine that feels realistic is far more important than trying to exercise as often as possible.
Building fitness is a gradual process. Your body needs time to adapt to new physical activity, and giving yourself enough recovery between workouts is just as important as the workouts themselves.
If you’re building your fitness from home, our guide Home Cardio Workouts for Beginners: The Complete Guide explains how different home cardio workouts fit together, how to choose the right style of exercise and how to build a routine that supports your long-term health. This article focuses specifically on how often beginners should include cardio in their week.
There Isn’t One Perfect Number
It’s tempting to look for a simple answer such as “three times a week” or “every other day,” but everyone’s starting point is different.
Someone who already walks regularly, plays sport or cycles to school may be able to comfortably include more structured cardio sessions than someone who is only just becoming more active.
Rather than comparing yourself to other people, focus on building a routine that challenges you without leaving you feeling constantly tired or overwhelmed. Your fitness will improve much more consistently if your workouts become part of your normal lifestyle.
If you’re just getting started, How to Start Cardio at Home (Beginner Guide) explains how to build confidence before increasing the frequency of your workouts.
A Good Starting Point for Most Beginners
For many beginners, completing two or three structured cardio workouts each week is a sensible place to begin.
This gives your body enough time to recover while still allowing you to build consistency and improve your cardiovascular fitness. On the days between your structured workouts, you can stay active through everyday movement such as walking, cycling, playing sport or spending time outdoors.
This balanced approach often feels much more manageable than trying to exercise every day from the very beginning.
As those workouts begin to feel easier, you can gradually increase either the length of your sessions or the number of days you’re active each week.
Quality Matters More Than Quantity
Many beginners assume that exercising more often automatically leads to faster progress. In reality, the quality of your workouts is usually far more important than simply completing more of them.
Three enjoyable workouts that you perform consistently every week are likely to benefit you much more than six exhausting sessions that leave you too tired to continue.
The goal isn’t to fill every day with structured exercise. It’s to create a routine that feels enjoyable, sustainable and realistic alongside school, work and the rest of your life.

Listen to Your Body
Your body gives you valuable feedback about how your routine is working.
Feeling slightly tired after a workout is completely normal, especially when you’re beginning a new exercise routine. However, if you’re constantly exhausted, struggling to recover between sessions or feeling unusually sore every day, you may be trying to progress too quickly.
Recovery isn’t a sign that you’re falling behind. It’s the time when your body adapts to the exercise you’ve completed, allowing you to become stronger and fitter over time.
Learning to recognise the difference between normal tiredness and pushing yourself too hard is an important part of building a healthy relationship with exercise.
What Counts as Cardio?
It’s also important to remember that structured workouts aren’t the only form of cardiovascular exercise.
Walking, cycling, swimming, dancing, playing football with friends or even spending time being active outdoors all contribute towards your overall activity levels. Many beginners underestimate just how much these everyday activities help improve their cardiovascular fitness.
Adding more movement throughout your day often feels easier than trying to complete formal workouts every single day.
If you’ve ever wondered whether walking counts, Does Walking Count as Cardio? explains how everyday movement contributes to your fitness.
How to Progress Over Time
As your fitness improves, you don’t necessarily need to add more workouts every week. There are several ways to continue making progress while keeping your routine balanced.
You could:
- Exercise for a little longer during each session.
- Reduce your rest periods slightly.
- Increase the pace of your workouts.
- Introduce new exercises that challenge different muscle groups.
- Add one extra cardio session if you feel fully recovered.
There’s no need to make all of these changes at once. Small improvements repeated consistently are usually far more effective than dramatically increasing your workload overnight.

Do You Need Rest Days?
Yes. Recovery is an important part of becoming fitter.
Every time you exercise, your body adapts to the physical demands you’ve placed on it. Rest days give your muscles, joints and cardiovascular system time to recover before your next workout.
That doesn’t mean you have to spend the entire day sitting down. Gentle activities such as walking, stretching or cycling can help you stay active while giving your body a break from more structured exercise.
Many beginners actually make better progress by balancing activity with recovery rather than trying to work out every single day.
How Long Should Each Workout Be?
The number of workouts you complete is only one part of the picture. The length of each session matters too.
If you’re just beginning, shorter workouts often feel much more manageable. A 10-minute session may be enough to build confidence on busy days, while a 20-minute workout provides a little more time to improve your endurance.
As your fitness develops, you may naturally choose to exercise for longer, but there’s no pressure to rush that progression. Consistency is still the priority.
If you’re looking for structured sessions, 10-Minute Cardio Workout at Home and 20-Minute Cardio Workout at Home provide ready-made workouts for different schedules.
Should Every Workout Feel Difficult?
Not at all.
Many people believe they need to finish every workout feeling completely exhausted before it has been worthwhile. In reality, some sessions should feel more challenging than others.
Your breathing should become faster during cardio, but you shouldn’t feel like you’re struggling through every minute. Finishing a workout feeling like you could have continued for a little longer is often a sign that you’ve chosen an appropriate intensity.
As your fitness improves, the same workout will naturally begin to feel easier. That’s a positive sign that your cardiovascular fitness is improving.
Fit Cardio Around Your Lifestyle
The best workout schedule is the one you can realistically maintain.
Think about your school timetable, work, hobbies, sports and family commitments. Rather than trying to squeeze exercise into an already busy day, look for times that naturally fit your routine.
Some people prefer exercising before school or work, while others enjoy evening workouts. There’s no universally “best” time to do cardio. The most important thing is choosing a schedule that you’ll actually stick with.
If you’re planning your week, How to Build a Home Cardio Routine explains how to organise your workouts into a sustainable routine. If you’re struggling to stay consistent, How to Stay Motivated With Home Cardio Workouts offers practical ideas for building lasting habits.
Consistency Always Wins
When it comes to cardio, consistency almost always beats intensity.
Two or three enjoyable workouts every week for several months will usually produce much better results than exercising every day for a fortnight before giving up because the routine feels impossible to maintain.
Instead of asking yourself whether you’re doing enough, ask whether your routine is something you’ll still be following next month. If the answer is yes, you’re already moving in the right direction.
Bringing Everything Together
When you’re new to cardio, it’s natural to wonder whether you’re exercising enough or whether you should be doing more. In reality, the best routine is rarely the one with the most workouts—it’s the one you can maintain consistently without feeling overwhelmed.
For many beginners, two or three structured cardio sessions each week provide an excellent starting point. Combined with everyday movement such as walking, cycling or playing sport, this gives your body regular opportunities to become fitter while still allowing time for recovery.
As your confidence and cardiovascular fitness improve, you can gradually increase the length of your workouts, try new exercises or add an extra session if it fits comfortably into your lifestyle. There’s no need to rush. Fitness develops over weeks and months through regular movement, not through trying to do everything at once.
Most importantly, remember that consistency is more valuable than perfection. A realistic routine that you genuinely enjoy will almost always help you make better long-term progress than an ambitious schedule that’s impossible to maintain.
