How Long Should You Do Cardio? A Complete Guide
Understanding the Purpose of Cardio
Cardio, short for cardiovascular exercise, helps improve the health of your heart and lungs. It can also aid in weight loss, boost energy, and enhance overall fitness. Knowing how long to do cardio depends on your goals and current fitness level.
Typical Recommendations for Cardio Duration
Health experts often suggest aiming for at least 150 minutes of moderate-intensity cardio each week. This could be broken into sessions lasting about 30 minutes, five days a week. For more intense workouts, 75 minutes per week might be enough.
Factors Influencing How Long You Should Do Cardio
Several factors affect the ideal length of your cardio workouts. These include your age, fitness level, specific goals, and the type of exercise. It’s important to tailor your routine to match your personal needs.
Your Fitness Goals
- Weight loss: Longer sessions or higher intensity can help burn more calories.
- Improve endurance: Gradually increasing workout duration helps build stamina.
- Health benefits: Moderate sessions of 30-45 minutes improve heart health without overexertion.
Starting Out or Returning After a Break
Beginners should start slowly, doing about 10-20 minutes of doable activity. As fitness improves, they can gradually extend sessions to 30-45 minutes.
Advanced Fitness Levels
Those with higher fitness levels may do longer sessions or include interval training. Working up to 60 minutes or more can optimize results if recovery and health are not compromised.
Understanding Different Types of Cardio and Their Impact on Duration
Different cardio activities vary in intensity and duration. These include walking, jogging, cycling, swimming, and high-intensity interval training (HIIT).
Moderate-Intensity Cardio
Activities like brisk walking or steady cycling are considered moderate intensity. These are suited to sessions lasting 30-60 minutes to maximize health benefits while minimizing fatigue.
High-Intensity Cardio
Activities such as sprinting, intense cycling, or HIIT are more demanding. They often require shorter durations, typically 15-30 minutes, to prevent overtraining.
Low-Impact Cardio
Walking or swimming are gentle options that allow longer durations without stressing joints. You can aim for 45-60 minutes depending on your comfort level.
How to Structure Your Cardio Routine
Creating a balanced plan involves choosing the right duration and intensity. Incorporate variety to prevent boredom and maximize effectiveness.
Sample Weekly Cardio Schedule
- Monday: 30-minute brisk walk
- Tuesday: 20-minute HIIT session

Listening to Your Body
While guidelines are helpful, paying attention to how your body feels is essential. Stop or adjust your workout if you experience pain or extreme fatigue.
Signs You Might Need to Shorten or Lengthen Your Sessions
- Feeling drained or dizzy: reduce duration or intensity.
- Feeling energized and good afterward: you may increase your workout time.

Rest and Recovery
Rest days are vital for avoiding overtraining and injuries. Even during active recovery, light activities like stretching or walking can be beneficial.
Monitoring Your Progress and Adjusting Duration
Track your workouts to see what works best. If your goal is weight loss, longer or more intense sessions might be necessary. For overall health, consistency matters more than length.
Common Mistakes to Avoid
- Overdoing cardio and risking injury or burnout.
- Not gradually increasing duration or intensity.
- Ignoring signs of fatigue or pain.
Incorporating Fun and Variety
