Aerobic exercise is one of the most complete and recommended forms of physical activity for improving heart health, strengthening the respiratory system, reducing stress, and aiding in weight management. This type of exercise is characterized by requiring a constant supply of oxygen to produce energy, which implies sustained, moderate-intensity activity.
Brisk walking, swimming, running, cycling, and dancing are clear examples of aerobic exercise. Regular practice improves not only physical fitness but also metabolic, emotional, and functional aspects of the body. Although it is often confused with or compared to anaerobic exercise, the two have distinct differences that are important to understand in order to achieve a balanced workout tailored to individual goals.
What exactly is aerobic exercise?
Aerobic exercise relies on the use of oxygen as the primary energy source during prolonged activity. For this to occur, the intensity of the exercise must be maintained within a range where the body can sustain the effort for several minutes without becoming exhausted quickly.
This means it’s not about explosive or maximum strength exercises, but rather moderate and continuous efforts that engage large muscle groups, such as the legs and back. The minimum recommended duration to reap benefits is about 30 minutes per session, at least three times a week.
Among the most notable effects of aerobic exercise are:
- Improved cardiovascular capacity
- Reduction of blood pressure
- Increased fat metabolism
- Reduced risk of chronic diseases
- Greater physical endurance and lung capacity
- Positive effect on mood and sleep

Differences between aerobic and anaerobic exercise
Aunque ambos tipos de ejercicio aportan beneficios a la salud, el ejercicio aeróbico y el anaeróbico tienen mecanismos energéticos y objetivos diferentes. Entender sus diferencias es importante para diseñar un plan de entrenamiento equilibrado.
Aerobic exercise
- It uses oxygen to produce energy
- It is performed for extended periods (more than 3-5 minutes)
- La intensidad es moderada y constante
- It improves endurance and cardiovascular health
- Examples: walking, jogging, swimming, cycling, dancing
Ejercicio anaeróbico
- It uses energy sources without the presence of oxygen.
- Son esfuerzos intensos y breves (de segundos a 2 minutos)
- It focuses on strength and muscle power
- It promotes muscle growth and speed
- Examples: weightlifting, sprints, HIIT exercises
Both types can complement each other within a weekly routine, as long as they are adapted to each person’s level and goals. While aerobic exercise improves cardiovascular fitness, anaerobic exercise develops strength and explosiveness.
Beneficios reales del ejercicio aeróbico en la salud integral
Regular aerobic exercise has a direct impact on multiple body systems. Among the most notable benefits are:
- Stronger heart: the heart becomes more efficient, pumping more blood with less effort.
- Reduction of bad cholesterol and increase of good cholesterol: a healthier lipid profile is promoted.
- Improved glycemic control: ideal for preventing or managing type 2 diabetes.
- Body weight regulation: by increasing caloric expenditure and improving metabolism.
- More resilient immune system: Constant movement improves the immune response.
- Less stress and better mood: thanks to the release of endorphins during exercise.
- Prevention of premature aging: by improving cellular oxygenation and mitochondrial function.
It is also a very useful tool in the prevention of chronic diseases, such as hypertension, obesity, osteopenia, metabolic syndrome and cardiovascular diseases.

How to start an aerobic exercise routine?
Para comenzar una rutina de ejercicio aeróbico, no hace falta tener una gran condición física ni apuntarse a un gimnasio. Lo importante es empezar de forma progresiva, escuchar al cuerpo y mantener una regularidad mínima.
Basic recommendations to get started:
- Choose an activity that is enjoyable (walking, dancing, swimming)
- Start with 20-30 minute sessions, 3 times a week
- Gradually increase duration and intensity
- Wear comfortable clothing and appropriate footwear
- Maintain good hydration
- Consult your physical therapist or doctor if there is a history of heart disease or injury
Consistency is key to making aerobic exercise a habit. Ideally, it should be integrated into your daily routine, either as a means of transportation or as part of recreational activities.
What happens if I combine aerobic and anaerobic exercise?
Combining aerobic exercise with anaerobic training (such as strength training or HIIT) offers more comprehensive results. While one improves endurance and cardiovascular health, the other builds muscle mass, power, and joint protection.
A well-structured plan may include:
- 3 weekly sessions of moderate aerobic exercise
- 2 Strength or Power Sessions on Alternate Days
- Stretching or yoga to maintain mobility
- Active rest days or gentle walks
This approach is ideal for people seeking comprehensive health, physical performance, or weight management with long-term sustainability.
The Role of Aerobic Exercise in Rehabilitation and Physical Therapy
Aerobic exercise is also fundamental within rehabilitation and physiotherapy programs. In patients with respiratory, metabolic, joint, or cardiovascular problems, a well-dosed aerobic routine can accelerate recovery and improve quality of life.
It is used, for example, in:
- Post-COVID recovery or lung disease
- Rehabilitation from heart surgery or heart attack
- Chronic back pain or fibromyalgia
- Control of overweight and improvement of metabolism
- Exercise Programs for Older Adults
It should always be prescribed by professionals, adapted to the individual’s physical condition, and monitored in the initial phases. It is a powerful tool, but it must be applied with clinical judgment.
