What is aerobic training, and why does it matter so much for your health?

Aerobic training is the foundation of lasting health, mental energy and physical resilience. Whether you want to lose weight, build cardiovascular fitness or bring your stress levels down, aerobic exercise delivers profound benefits, both physiological and hormonal. In this article you'll find out exactly what aerobic training involves, how it differs from anaerobic training, which aerobic exercises actually work, and why even people with asthma stand to gain from this kind of effort. We've tied these insights to clinical research on heart rate and autonomic regulation and to a randomised study in asthma.

What does 'aerobic' actually mean?

The word 'aerobic' literally means 'with oxygen'. During aerobic activity your body uses oxygen to release energy (ATP) from carbohydrates and fatty acids. This happens mainly in the mitochondria of your muscle cells. At low to moderate intensity, the oxygen supply is plentiful enough for that process to run efficiently. Almost no lactic acid builds up as a result, which is why you can keep this kind of training going for a long time.

What counts as aerobic training?

Aerobic training is movement that raises your heart rate while still leaving you able to breathe comfortably – typically between 60 and 80 % of your maximum heart rate. Research by Almeida & Araújo (2021) highlights that well-trained people have a lower resting heart rate thanks to increased parasympathetic (vagal) activity. That doesn't just make for a more efficient heart rhythm – it also lowers the risk of cardiovascular mortality.

What are aerobic exercises?

Aerobic exercises are activities that keep your body moving for a sustained period at low to moderate intensity. Some of the most accessible and effective forms are:

  • Brisk walking – ideal for fat burning
  • Easy jogging – builds endurance
  • Swimming – works well for people with joint problems too
  • Cycling – excellent for fat oxidation in zone 2
  • Bouncing on a trampoline – raises oxygen consumption without overloading the joints
  • Stability work with an exercise ball or balance board – combines coordination with cardiovascular work
  • Bodyweight workouts on an exercise mat or step platform – aerobic interval formats such as LISS

What's the difference between aerobic and anaerobic training?

In aerobic training, oxygen is central to energy production. In anaerobic training the intensity is so high (80-100 % of your maximum heart rate) that your body can't supply enough oxygen. Energy is then produced through glycolysis, which generates lactic acid. Anaerobic training – sprints, or strength work with a slam ball or medicine ball, for instance – is short, explosive and acidifying. Aerobic training, by contrast, is sustained, oxygen-dependent and restorative.

Is fat burning anaerobic?

Fat burning is an aerobic process. Your body needs oxygen to break fatty acids down in the mitochondria. That's why moderate, continuous effort such as walking or cycling is far more effective for burning fat than anaerobic work. During anaerobic training you're drawing mainly on glucose, because it delivers energy faster without oxygen.

What are the benefits of aerobic training?

According to the study by Almeida & Araújo (2021), aerobic training improves vagal tone, which produces a lower resting heart rate, better heart rate variability (HRV) and faster heart rate recovery after exertion. All of that points to a more resilient autonomic nervous system – essential for regulating stress, sleeping well and protecting cardiovascular health. How quickly your heart rate recovers within the first minute after exercise is itself a strong predictor of survival. People who recover more slowly are up to twice as likely to die prematurely.

Which activities are highly aerobic?

Activities that place a high aerobic demand on the body include:

  • Tempo running (>30 min)
  • Spinning or interval cycling
  • Sustained swimming sessions
  • Trampoline bouncing routines
  • Step aerobics with an exercise mat and light weights

These improve maximum oxygen uptake (VO₂max), which correlates directly with a lower risk of cardiovascular disease and a longer life expectancy.

Is walking aerobic?

Yes – walking is the simplest form of aerobic movement there is. It's easy to start, kind to the joints and highly effective for both fat burning and cardiovascular development. For extra benefit, use an exercise ball or foam roller afterwards to improve mobility and circulation.

How should you train aerobically?

Want to train aerobically and do it efficiently? Follow these guidelines:

  • Train 3-5 days a week for 30-60 minutes
  • Keep your heart rate in zone 2 (60-75 % of your maximum HR)
  • Use a heart rate monitor, or the talk test – can you still hold a conversation?
  • Mix things up with kit such as a balance board, trampoline or exercise mat

Aerobic training as an anti-inflammatory in asthma

A landmark study by Mendes et al. (2011) examined the effect of aerobic training in patients with moderate to severe asthma. After three months of controlled, VO₂max-based aerobic training, participants showed a significant fall in sputum eosinophils and lower nitric oxide readings (FeNO) – both important markers of airway inflammation.

There was also a clear increase in the number of symptom-free days and a reduction in asthma exacerbations. The effects were strongest in participants with the highest baseline inflammation, suggesting it's precisely this group that stands to benefit most from targeted aerobic therapy.

Which is better: aerobic or anaerobic?

The best training regime combines the two. Aerobic training is ideal for fat burning, cardiovascular health, brain function and stress reduction. Anaerobic training is essential for building muscle, bone density and raw strength. A well-balanced week might look like this:

  • Monday: walking or cycling (45 min, zone 2)
  • Wednesday: strength circuit with a medicine ball, slam ball or step
  • Friday: trampoline HIIT (alternating aerobic and anaerobic)
  • Sunday: yoga or breathing exercises on an exercise mat

Conclusion

Aerobic training isn't a luxury – it's a necessity for anyone who wants to be healthy, energetic and resilient under stress. It supports your heart, your lungs, your brain and your mood. Backed by clinical research, it also proves a powerful weapon against heart disease and, according to the scientific evidence, against airway inflammation too. Make intelligent use of kit such as a foam roller, balance board or trampoline and you'll make your training more effective and more enjoyable at the same time.
