The Power of Cardio: No Such Thing as Too Much Exercise for Overall Health

Cardiovascular exercise, often known as cardio, has been a hot topic in the fitness world for years. While many believe in its numerous health benefits, a common concern has been the potential harm from excessive cardio. However, new research challenges this belief, suggesting that there might be no such thing as too much cardio exercise. The study highlights the potential benefits of sustained aerobic activity for overall health and well-being, dispelling the notion of ‘too much cardio’.

The Significance of Aerobic Exercise

Aerobic exercise, which includes activities such as swimming, jogging, and cycling, is essential for overall endurance and cardiovascular health. It has been extensively studied for its numerous health advantages. These include combating diseases related to a sedentary lifestyle, improving mental health, and maintaining a healthy weight. Whether it’s a Zumba class, a brisk walk in the park, a run on the treadmill, or a cycling session, these aerobic activities play a crucial role in keeping us fit and healthy.

Physical Activity and Creative Thinking

Furthermore, aerobic exercise not only enhances physical health but also stimulates creative thinking. Activities like walking at a natural pace, engaging in moderate intensity aerobic exercise, and dance have been found to enhance divergent thinking. However, there is a need for more comprehensive exploration into understanding the effects of resistance exercise and structured moderate to vigorous intensity aerobic exercise on creative cognition. This showcases the multifaceted benefits of aerobic exercise, stretching beyond physical wellness into cognitive enhancement.

High Intensity Interval Training (HIIT) vs Moderate Intensity Continuous Training (MICT)

When it comes to the intensity of the exercise, a meta-analysis compared the effects of High Intensity Interval Training (HIIT) and Moderate Intensity Continuous Training (MICT) on cardiovascular risk factors in adolescents. The findings showed that HIIT was better than MICT for improving cardiovascular health in adolescents, with better effects on body weight, BMI, fat mass, systolic blood pressure, diastolic blood pressure, maximal oxygen uptake, and other metabolic factors.

Exercise and Cardiometabolic Health

Regular exercise remains a cornerstone in the prevention and treatment of non-communicable diseases. It induces tissue-specific adaptations that enhance cardiometabolic health, including improved cardiorespiratory fitness, physical function, and glycemic control. The associated metabolic stress of each individual exercise bout provides the basis for long-term adaptations across tissues, ultimately improving cardiometabolic health. This reaffirms the importance of regular aerobic exercise in maintaining good health and preventing diseases.

Exercise for Brain Health

Finally, not only does aerobic exercise contribute to physical health, it also provides significant mental benefits. Researchers from the University of South Australia found that high intensity interval training and continuous moderate exercise deliver greater benefits to the brain than sustained strenuous exercise. The greatest changes in neuroplasticity occurred with 20 minutes of interval training or 25 minutes of continuous moderate aerobic exercise. This suggests that integrating regular cardio exercise into our daily routine could result in substantial cognitive advantages, alongside the physical benefits.

In conclusion, whether your goal is to enhance physical health, stimulate creative thinking, improve cardiovascular risk factors, or boost brain health, cardio exercise appears to be a powerful tool. So, lace up your sneakers, get your heart pumping, and embrace the power of cardio for a healthier and happier life.

Higher fitness levels linked to lower risk of depression, dementia – Harvard Health
research review

People with high cardiorespiratory fitness were 36% less likely to experience depression and 39% less likely to develop dementia than those with low cardiorespiratory fitness. Even small improvements in fitness were linked to a lower risk. Experts believe that exercise’s ability to boost blood flow to the brain, reduce bodywide inflammation, and improve stress regulation may explain the connection.

These 20-Minute Burpee Workouts Replaced His Entire Gym Routine – and Transformed His Physique

These 20-Minute Burpee Workouts Replaced His Entire Gym Routine – and Transformed His Physique

While many swear by them, most people see burpees as a form of punishment – usually dished out drill sergeant-style by overzealous bootcamp PTs. Often the final blow in an already brutal workout, burpees are designed to test cardiovascular fitness, muscular endurance and mental grit. Love them or loathe them, they deliver every time.

For Max Edwards – aka Busy Dad Training on YouTube – they became a simple but highly effective way to stay fit and lean during lockdown. Once a committed powerlifter, spending upwards of 80 minutes a day in the gym, he was forced to overhaul his approach due to fatherhood, lockdown and a schedule that no longer allowed for long, structured lifting sessions.

‘Even though I was putting in hours and hours into the gym and even though my physique was pretty good, I wasn’t becoming truly excellent at any physical discipline,’ he explained in a YouTube video.

‘I loved the intentionality of training,’ says Edwards. ‘The fact that every session has a point, every rep in every set is helping you get towards a training goal, and I loved that there was a clear way of gauging progression – feeling like I was developing competence and moving towards mastery.’

Why He Walked Away From Powerlifting

Despite that structure, Edwards began to question whether powerlifting was sustainable long-term.

‘My sessions were very taxing on my central nervous system. I was exhausted between sessions. It felt as if I needed at least nine hours of sleep each night just to function.’

He also noted that his appetite was consistently high.

But the biggest drawback was time.

‘I could not justify taking 80 minutes a day away from my family for what felt like a self-centred pursuit,’ he says.

A Simpler Approach That Stuck

‘Over the course of that year I fixed my relationship with alcohol and I developed, for the first time in my adult life, a relationship with physical training,’ says Edwards.

With limited time and no access to equipment, he turned to burpees. Just two variations, four times a week, with each session lasting 20 minutes.

‘My approach in each workout was very simple. On a six-count training day I would do as many six-counts as I possibly could within 20 minutes. On a Navy Seal training day I would do as many Navy Seal burpees as I could within 20 minutes – then in the next workout I would simply try to beat the number I had managed previously.’

This style of training is known as AMRAP – as many reps (or rounds) as possible.

The Results

Edwards initially saw the routine as nothing more than a six-month stopgap to stay in shape. But that quickly changed.

‘I remember catching sight of myself in the mirror one morning and I was utterly baffled by the man I saw looking back at me.’

He found himself in the best shape of his life. His energy levels improved, his resting heart rate dropped and his physique changed in ways that powerlifting hadn’t quite delivered.

‘It has been five years since I have set foot in a gym,’ he says. ‘That six-month training practice has become the defining training practice of my life – and for five years I have trained for no more than 80 minutes per week.’
