Boosting Exercise Intensity Reduces Mortality Risk, Study Suggests

If you want to live longer, you might want to push yourself just a little harder during your next gym visit: a new study reveals that putting extra strain on your body when you exercise matters more than squeezing in another session.

Researchers from the University of Basel in Switzerland and the University of Leicester in the UK have shown the intensity of your exercise can be more important than the time spent engaging in physical activity.

The team amassed three years of fitness tracker information covering a total of 7,518 adults in the US, with mortality data logged for an additional four years after that.

Higher intensity physical activity was found to be associated with comparitively lower risk of an early death from all causes, but the difference was most noticeable when it came to cardiovascular disease – think strokes, artery disease, and other heart problems.

“Higher intensity stimulates the cardiovascular system more,” says University of Basel sports scientist Fabian Schwendinger.

“This improves vascular function and cardiorespiratory fitness … the performance of the cardiovascular and respiratory systems.”

Boosting the speed of your regular jogs, or taking the stairs instead of the lift are just two ways daily activity can be given a healthy boost. To take one example from the data, an extra 150 minutes of brisk walking during the week could reduce mortality risk by as much as 28 percent, the study reports. That’s a significant benefit for not much extra effort.

The research chimes with previous studies that found greater intensity during exercising can have positive health effects, though the study also compared directly against the total duration of exercising.

“One of the great strengths of our study is that it included people with very different levels of fitness and health,” says Schwendinger.

“This means that everyone, regardless of whether they are very athletic or inactive, can benefit from the knowledge that intensity reduces mortality.”

The study authors also found that intense physical activity seems to be most beneficial when it’s done in one session, rather than spread out over the day.

To be clear, more exercise of any intensity is helpful. What’s more, there is such a thing as overdoing it. There will come a point when exercising harder won’t give you any extra years on the end of your life, and may actually start doing damage to your body instead.

“It’s not about people only living longer if they train extremely intensively, wear themselves out and are completely out of breath,” says Schwendinger.

The research has been published in the European Journal of Preventive Cardiology.

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.’
