Cardio is one of the best ways to burn calories and lose weight. But how much cardio do you really need? Some people believe that hours of running are the only way to slim down, while others say short workouts can be just as effective. The truth is, the right amount of cardio depends on your goals, lifestyle, and fitness level.
In this article, we will explore how much cardio you should do to lose weight, the best types of cardio for fat loss, and how to balance cardio with other exercises for the best results.
What Is Cardio and Why Does It Help With Weight Loss?
Cardio, short for cardiovascular exercise, includes activities that increase your heart rate and make you breathe harder. Common examples are running, cycling, swimming, walking, and jumping rope.
Cardio helps with weight loss because it burns calories. When you burn more calories than you eat, your body uses stored fat for energy. This process, called a caloric deficit, leads to weight loss.
Besides burning calories, cardio also improves heart health, increases stamina, and reduces stress. But too much cardio can lead to muscle loss, fatigue, and injuries. That’s why it’s important to find the right balance.
How Many Hours of Cardio Per Week to Lose Weight?
The amount of cardio you need depends on how much weight you want to lose and how fast you want to lose it.
1. General Guidelines for Weight Loss
The American Heart Association (AHA) and the Centers for Disease Control and Prevention (CDC) recommend:
- 150–300 minutes of moderate-intensity cardio per week (such as brisk walking or cycling)
- 75–150 minutes of vigorous-intensity cardio per week (such as running or HIIT workouts)
If your goal is to lose weight, you should aim for at least 300 minutes of moderate cardio or 150 minutes of vigorous cardio per week. This means about 5 hours of moderate exercise or 2.5 hours of vigorous exercise weekly.
2. Faster Weight Loss: More Cardio
If you want to lose weight faster, increasing your cardio time can help. Some people do 60 minutes of cardio daily to speed up fat loss. However, it’s important to avoid overtraining, which can lead to burnout or injury.
A good approach is:
- 30–60 minutes of moderate-intensity cardio per day, 5–6 days per week
- 20–30 minutes of high-intensity cardio per day, 4–5 days per week
3. Slow and Steady Weight Loss
If you prefer a slower and more sustainable approach, 3–4 hours of moderate cardio per week (or about 30–45 minutes per day) can help you lose weight over time without too much stress on your body.
Best Types of Cardio for Weight Loss
Not all cardio exercises are equal when it comes to burning fat. Here are the most effective ones:
1. High-Intensity Interval Training (HIIT)
HIIT involves short bursts of intense exercise followed by rest periods. For example, you sprint for 30 seconds and then walk for 1 minute.
Benefits of HIIT for weight loss:
- Burns a lot of calories in a short time
- Increases metabolism for hours after exercise (afterburn effect)
- Preserves muscle while losing fat
Recommended time: 20–30 minutes per session, 3–4 times a week
2. Steady-State Cardio
This is moderate-intensity cardio done at a constant pace, such as jogging, cycling, or brisk walking.
Benefits of steady-state cardio:
- Easier to do for beginners
- Improves endurance and cardiovascular health
- Can be done for longer periods
Recommended time: 30–60 minutes per session, 4–6 times a week
3. Walking
Walking is a great option for beginners or those who want low-impact exercise.
Benefits of walking for weight loss:
- Easy on the joints
- Can be done anywhere
- Helps maintain a calorie deficit with less stress on the body
Recommended time: 60–90 minutes per day for noticeable weight loss
4. Jump Rope
Jumping rope is a full-body workout that burns a lot of calories quickly.
Benefits of jump rope:
- Improves coordination and agility
- Strengthens the legs and core
- Can be done in short sessions with high calorie burn
Recommended time: 15–30 minutes per session, 3–5 times per week
How to Combine Cardio and Strength Training
Many people focus only on cardio, but adding strength training can make weight loss more effective.
Why include strength training?
- Builds muscle, which increases metabolism
- Helps tone the body and prevent loose skin
- Prevents muscle loss during weight loss
A good weekly plan could be:
- 3–5 days of cardio
- 2–3 days of strength training
- At least 1 rest day for recovery
How to Avoid Overtraining and Burnout
Too much cardio can lead to fatigue, injury, and muscle loss. Here’s how to avoid that:
- Listen to your body – If you feel exhausted, take a break.
- Mix different types of cardio – Avoid repetitive stress on joints.
- Get enough sleep – Sleep is crucial for recovery and fat loss.
- Eat a balanced diet – Fuel your body with protein, healthy fats, and complex carbs.
Conclusion
The right amount of cardio for weight loss depends on your fitness level and goals. A general rule is to aim for at least 5 hours of moderate cardio or 2.5 hours of vigorous cardio per week.
For faster results, increase your cardio time, but don’t forget to balance it with strength training and rest. The most important thing is to stay consistent and find an exercise routine that you enjoy.
