Cardio Training
Improve heart health, burn calories, and boost endurance with effective cardiovascular exercises for all fitness levels
What is Cardio Training?
Cardiovascular training, commonly known as cardio, focuses on exercises that increase your heart rate and breathing for an extended period. These workouts strengthen your heart and lungs, improve circulation, and help your body become more efficient at delivering oxygen to your muscles.
Unlike strength training which primarily builds muscle mass, cardio exercises enhance your aerobic capacity, allowing you to sustain physical activity for longer periods without fatigue. Regular cardio workouts burn calories, help with weight management, and improve overall health markers like blood pressure and cholesterol levels.
Whether you prefer high-intensity interval training (HIIT), steady-state cardio, or group classes, incorporating regular cardiovascular exercise into your routine is essential for a well-rounded fitness program and long-term health.
Key Benefits
Stronger Heart
Regular cardio training strengthens your heart muscle, allowing it to pump more blood with less effort and reducing the risk of heart disease.
Improved Lung Capacity
Cardiovascular exercise increases your lung capacity and efficiency, helping your body better utilize oxygen and remove carbon dioxide.
Calorie Burning
Cardio workouts are highly effective for burning calories during and after exercise, supporting weight management and fat loss goals.
Increased Energy
Regular cardiovascular training improves mitochondrial density in cells, enhancing your body's energy production and reducing fatigue.
Mental Health Benefits
Aerobic exercise releases endorphins that reduce stress, anxiety, and depression while improving cognitive function and mood.
Better Sleep
Regular cardio can help regulate your sleep patterns, improve sleep quality, and reduce the time it takes to fall asleep.

Recommended Guidelines
health organizations recommend the following guidelines for cardiovascular exercise to maintain health and fitness:
| Goal | Frequency | Duration | Intensity |
|---|---|---|---|
| General Health | 5 days/week | 30 minutes | Moderate (Zone 2-3) |
| Weight Management | 5-6 days/week | 45-60 minutes | Moderate to Vigorous (Zone 3-4) |
| Athletic Performance | 3-5 days/week | Variable (30-90 minutes) | Mixed (Zone 2-5) |
| Beginners | 3 days/week | 20-30 minutes | Light to Moderate (Zone 1-2) |
Tips for Beginners
If you're new to cardio training, start slowly and gradually increase the duration and intensity of your workouts. Begin with 10-20 minutes of light activity and add 5 minutes each week. Mix different types of cardio to keep it interesting and reduce the risk of overuse injuries. Remember that consistency is more important than intensity when you're starting out.
Listen to your body and don't push through pain (as opposed to normal exercise discomfort). Stay hydrated before, during, and after your workout, and consider using a heart rate monitor to ensure you're training in the appropriate zones for your goals.
Frequently Asked Questions
The best time to do cardio is whenever you can consistently fit it into your schedule. Some research suggests morning cardio may enhance fat burning and improve sleep, while afternoon workouts might allow for better performance due to higher body temperature. However, consistency matters more than timing, so choose a time that works with your lifestyle.
Fasted cardio (exercising on an empty stomach) may slightly increase fat oxidation during the workout, but research shows the overall difference in fat loss is minimal compared to fed-state cardio. If you feel good exercising fasted, it's fine for moderate-intensity sessions. For high-intensity workouts, having some fuel can help maintain performance and prevent muscle breakdown.
When done appropriately, cardio won't significantly impact muscle mass. Excessive cardio (more than 5-6 hours weekly) combined with inadequate calorie intake and resistance training may lead to some muscle loss. To maintain muscle while doing cardio, ensure you're consuming enough protein (1.6-2.2g per kg of bodyweight), continue strength training regularly, and consider keeping high-intensity cardio sessions shorter (20-30 minutes).
For general health benefits, aim for at least 150 minutes of moderate-intensity cardio spread across 3-5 days per week. If you're doing high-intensity cardio, 75 minutes per week (2-3 sessions) can provide similar benefits. Those with specific goals like weight loss may benefit from 4-6 sessions weekly. Remember to include rest days and listen to your body to prevent overtraining.
If you're prioritizing strength gains, do strength training first when your energy levels are highest. If your primary goal is cardiovascular fitness or endurance, do cardio first. For general fitness, you can separate cardio and strength into different sessions or different days. If you must do both in one session, your priority goal should determine the order.
