While relaxing into the holidays with the activity intensity of a good book and a float in the ocean is an entirely sensible idea, if you need to shake out all the festivities, you might want to set aside a little time for some strength.

And although there is nothing fancy about bodyweight exercises such as push-ups, sit-ups and squats, in 2019 these humble moves continued to prove they punch well above their weight.

A study released last week, from the University of Missouri, found that older adults who completed an eight-week strength-based program, which included exercises such as squats and bicep curls, “improved significantly” in their strength, in their balance and in their sleep quality.

One study from November found strength training (including bodyweight training) is as good as aerobic exercise for weight management, while another found it is also as effective as aerobic training for reducing the likelihood of depression (though the combination of the two was the most effective).

Separate research from October found that we are four times less likely to have a heart attack if we exercise regularly, incorporating both strength and aerobic, while another study, published in July, found that resistance training improves the ability to think and reduces age-related memory loss. At least it does in rodents.



Dr Jason Bennie, a senior research fellow from the University of Southern Queensland, has led and been involved with many of the latest studies into strength.

He says “there is some research to suggest” that compared with aerobic exercise, strength training has “more favourable effects” on cognitive function and memory.

“Other things such as ‘mastery’ of skills, and the fact that [strength training] occurs most likely during leisure time, where someone has the freedom to do this activity, are all likely to play a role,” he adds.

Previous research has found doing strength-based exercise just twice a week supports metabolism and bone density as we age as well as cognitive function. Strength training improves insulin sensitivity, markers of glucose metabolism as well as lipid metabolism, increasing HDL cholesterol and decreasing LDL cholesterol.

It is also linked with a 23 per cent reduction in risk of premature death by any means, and a 31 per cent reduction in cancer-related death.

All of this is important for two reasons. The first is that, historically, fitness research has focused on aerobic exercise and secondly because too few of us do enough aerobic exercise and even fewer do enough strength.

More than half of Australian adults don’t meet the physical activity guidelines of 30 minutes of moderate physical activity five days a week, nearly 80 per cent don’t meet the muscle strength guidelines of two sessions a week and only 15 per cent of Australian adults meet both.

Yet adding some squats, sit-ups and push-ups requires no equipment nor any special location. You can crack a few each evening on your living room floor while you watch Netflix and, mostly, chill.

An added advantage to starting these three exercises this week is that they also take very little time, and starting with something very short and very easy is the best way to establish a new habit, according to experts.

Starting with whatever you can squeeze into 30 seconds or two minutes “helps you effectively wire in the behaviours you want so they become habits and grow naturally,” explains B.J. Fogg, director of Stanford’s Behaviour Design Lab, in his book, Tiny Habits.

So while these exercises might seem glaringly obvious and basic, they may just be the gateway to a healthier, fitter and stronger new decade for you.
