Exercise 'sweet spot' you need to hit to live longer – it's less than you think
SCIENTISTS have revealed the exercise ‘sweet spot’ you need to hit to live longer.
It’s no secret that working out is a key part of staying healthy for longer – but you don’t need to spend hours at the gym each week to reap the benefits, scientists from the University of Jyväskylä in Finland said.

In fact, moderate levels of activity could be enough to lower your risk of death, they suggested.
Finnish researchers studied the exercise habits of 22,750 twins, following up with them after 15 and 30 years to assess their biological age and risk of mortality.
They split participants up into four groups:
- Sedentary
- Moderately active
- Active
- Highly active
Moderate-movers seemed to reap the most benefits from exercise, with a seven per cent lower risk of death compared to people who didn’t work out.
Though higher levels of exercise were found to lower the risk of mortality in the short-term, it actually brought no additional benefit in the long-term, researchers said.
They found that highly active participants didn’t get any more benefit to their mortality risk – essentially, more is not necessarily better.
Associate professor Elina Sillanpää from the Faculty of Sports and Health Sciences suggested that the idea that ‘being sedentary increases the risk of death’ is incorrect.
Instead, he says: “An underlying pre-disease state can limit physical activity and ultimately lead to death, not the lack of exercise itself.
“This can bias the association between physical activity and mortality in the short term.”
The twins participating in the study were all born before 1958 and their physical activity was assessed through questionnaires in 1975, 1981 and 1990.
Over a third (38.8 per cent) of the participants from the sedentary class died during the 30-year follow-up period, compared to 30.8 per cent of the moderately active group, 29 per cent of the active group and 25.4 per cent of the highly active group.
Moderately active and sporty participants had a 16 and 24 per cent lower risk of death compared to the sedentary group.
But after researchers factored in lifestyle-related factors and participants’ body mass index, their risk was only reduced by seven and nine per cent.
“But the moderately active and active classes exhibited lower risks of all-cause mortality compared to the sedentary class and highly active class within all pairs,” researchers wrote in the study published to Nature.
How researchers worked out activity levels
Participants’ levels of physical activity were measured using questionnaires, which looked at how much they moved or worked out each week, how long for and how intense the bouts were.
Each answer was assigned a score, after which participants were divided into their four groups.
The questionnaires differed slightly between 1975 and 1981, and 1990.
Here’s what the one used in 1990 looked like:
The following questions are about your physical activity during leisure time or during your daily journey to work during last 12 months.
How many hours in week you engage in physical activity corresponding to each intensity level?
Intensity levels:
- Walking
- Alternatively walking and jogging
- Jogging
- Running
Duration:
- Not at all
- Less than 30 minutes a week
- Between 30 minutes and less than an hour a week
- Two to three hours a week
- Four hours of more a week
The researchers also investigated whether following the World Health Organization’s physical activity guidelines affects mortality and genetic disease risk.
The guidelines advise adults to do 150 to 300 minutes of moderate or 75 to 150 minutes of vigorous activity weekly.
The study found that meeting these guidelines did not lower people’s risk of death or change their genetic risk.
Even for twins who met the recommended levels of exercise over a 15-year period, there wasn’t a difference in mortality rates compared to their less active twin pair.
Finally, researchers estimated the biological age of participants, looking at how it changed according to exercise levels.
They did this by taking blood samples from participants to get a sense of how fast the cells in their bodies were ageing.
Biological age – the age of our cells – measures how well your body functions and how much wear and tear it’s experienced.
It may be a better indicator than chronological age of how long we’ll will live and be in good health for.
Prof Sillanpää said: “We found that the association between leisure-time physical activity and biological aging was U-shaped.
“Biological ageing was accelerated in those who exercised the least and the most.”
Highly active people were on average, 1.2 years biologically older than the moderately active group and 1.6 years biologically older than the active group.
What counts as moderate exercise?
Moderate activity will raise your heart rate, and make you breathe faster and feel warmer.
One way to tell if you’re working at a moderate intensity level is if you can still talk, but not sing.
Examples of moderate intensity activities include:
- Brisk walking
- Water aerobics
- Riding a bike
- Dancing
- Doubles tennis
- Pushing a lawn mower
- Hiking
- Rollerblading
The NHS recommends that adults between 19 and 64 should aim to:
- Do at least 150 minutes of moderate intensity activity a week or 75 minutes of vigorous intensity activity a week
- Spread exercise evenly over four to five days a week, or every day
- Reduce time spent sitting or lying down and break up long periods of not moving with some activity
- Do strengthening activities that work all the major muscle groups (legs, hips, back, abdomen, chest, shoulders and arms) on at least two days a week
Examples of vigorous activities include:
- Running
- Swimming
- Riding a bike fast or on hills
- Walking up the stairs
- Sports, like football, rugby, netball and hockey
- Skipping
- Aerobics
- Gymnastics
- Martial arts

Jogging 101: Benefits for Your Body and Mind
Walking and running share a number of benefits — but what about that sweet middle ground between the two?

“Jogging is about creating a steady pace,” says sports and exercise medicine specialist Leonardo Oliveira, MD. “Instead of focusing on speed, you’re focused more on endurance with good, quality steps.”
Before your next jaunt, Dr. Oliveira shares the many benefits of jogging and how it can help improve your overall health and wellness.
9 benefits of jogging
Unlike running, where you’re focused on targeting different heart rate zones, jogging involves keeping a more stable and persistent pace. If you’re jogging at a moderate intensity, for example, your target heart rate will usually fall into zone 2, at 60% to 70% of your max heart rate.
“When you’re jogging, you should be able to carry on a conversation as you breathe through your nose,” says Dr. Oliveira. “If you’re doing just 15 minutes of jogging three times a week, you’re already going to notice the benefits.”
Here’s how you can benefit from jogging.
1. Reduces stress
Jogging, like other exercises, can help decrease your stress levels. As an aerobic exercise, it helps release endorphins, which can boost your mood and create feelings of euphoria or satisfaction. Not only does it provide an outlet for pent-up energy, but jogging outside also allows you to spend more time in nature, which provides even more mental health benefits.
“Research shows exercise can be as effective as medication when treating depression because of its wide-ranging benefits,” says Dr. Oliveira.
2. Burns calories
Jogging is a full-body exercise that offers a higher calorie burn than some other aerobic exercises. According to the widely used Compendium of Physical Activities, jogging burns about 7.5 calories per kilogram of body weight each hour. That means you can burn about:
- 8 times as many calories as sitting quietly
- 4 times as many calories as walking
- 2.6 times as many calories as stationary cycling
“Jogging will burn more calories in a shorter period of time than cycling, especially if you’re not used to exercising,” reports Dr. Oliveira.
3. Improves insulin resistance and boosts metabolism
Insulin resistance is one of the biggest barriers to having a healthy metabolism. Insulin helps your body break down glucose for energy. But if your body can’t do that, your metabolism slows down, leading to:
- Lower energy levels
- Weight gain
- An inability to burn fat
“Exercising at higher intensities helps increase metabolism and insulin resistance,” says Dr. Oliveira. “But researchers have also found that even lower-intensity exercises, like jogging, for longer periods of time can have the same effect.”
4. Strengthens your heart
Jogging also has positive impacts on your heart and its ability to pump blood to the rest of your body. That’s because it contributes to hypertrophy, or the strengthening of your heart’s muscle tissues.
“As you develop endurance, the amount of blood in one pump increases,” explains Dr. Oliveira. “When your heart gets stronger, it contracts more efficiently, which decreases your resting heart rate.”
5. Improves lung expansion and gas exchange
The more you work on building endurance and stamina, the more likely it is that you’ll improve your overall ability to breathe — both at rest and while jogging.
“Consistent aerobic exercise helps your lungs get stronger and more efficient,” says Dr. Oliveira. “Over time, you won’t need to breathe as often because each breath brings in more oxygen than before.”
6. Activates muscles
Jogging activates major muscle groups, including your:
- Quads
- Hamstrings
- Glutes
- Core
- Back
“Strength training is a good complement to jogging because it can help strengthen all the areas of your body,” says Dr. Oliveira. “This can help you handle longer distances.”
7. Reduces stiffness
“Jogging is one of those activities where once you get going, you start to feel better,” notes Dr. Oliveira. “It’s an exercise that helps warm up your muscles and lubricate your joints, which can help with the overall sense of stiffness that comes with age.”
That said, jogging is still a high-impact exercise because it forces you to bear down weight as your feet hit the pavement. Consider working with a physical therapist or athletic trainer to reduce the risk of further injury if you:
- Have arthritis
- Have an active injury
- Had previous sprains or fractures in your lower body
8. Improves endurance
“The more you jog, the more you’ll increase your functional aerobic capacity,” says Dr. Oliveira. “Someone who jogs regularly will have better physical fitness that will help them last longer on a bike or a walk than someone who’s just getting started.”
Your ability to breathe and move also extends to other daily activities that demand cardiovascular strength and endurance, like climbing stairs.
9. Provides better quality of life and other mental health benefits
Research shows that any amount of jogging — even just once a week — can improve your quality of life and lower your risk of dying from cancer and cardiovascular-related issues.
“Jogging is a great form of exercise, but it’s not the only one,” notes Dr. Oliveira. “The most important thing is to work on being healthy and strong. And for a lot of people, if you’re looking to advance your physical fitness, jogging is a good place to start.”

Michelle Yeoh, 63, uses ‘exercise snacking’ to stay fit – here’s why mini workouts have big benefits
As an increasing number of scientific studies are published citing the benefits of ‘exercise snacking’ – short bouts of physical activity sprinkled throughout the day – one celeb has sworn by the practise for several years already. The woman in question? Acting great Michelle Yeoh. Below, we look at the power of mini workouts and why the Oscar-winner’s go-to move is so effective.
Stretching
Michelle revealed to Vogue that she incorporates fitness into her morning routine in a way that’s incredibly time-efficient. ‘Remember, you can do your kicks, you can do your stretches, while you are also waking up,’ she said. Indeed, research has shown that regular stretching can improve flexibility, reduce muscle stiffness and improve blood circulation – all crucial elements of healthy ageing.
And you don’t have to stretch for very long, either. One study found that while static stretching improves flexibility in adults, there was no additional benefit observed beyond four minutes per session or 10 minutes per week. So, it seems that a short stretching sesh (you don’t even have to get out of bed to do it) like Michelle’s is a very worthwhile habit to adopt.
Squats
In her Vogue interview, Michelle also shared that she performs squats most days while doing her skincare routine. Virtually every expert and trainer we speak to here at Women’s Health lists squats as one of the most important moves for women to do as they age. A compound exercise (when multiple muscle groups are used), squats also mirror the vital movement pattern of sitting down and getting back up again.
Numerous studies have highlighted the benefits of this simple exercise for posture, strength and power, and one paper even found that intermittent squat exercises performed during prolonged periods of sitting may boost brain power. Whether you’re squatting mid-moisturise like Michelle or while you’re waiting for the kettle to boil, the science suggests sprinkling squats into your day can be really quite powerful.
The power of habit stacking
As Michelle’s routine shows, adopting a sustainable exercise routine often relies on habit stacking – adding a movement to something you already do every day, like doing your skincare or brushing your teeth.
BRB, we’re just off to do our daily squats.

I Have a Master’s in Exercise Science. These Are the Only 6 Strength Moves You Need To Build Muscle
Strength training doesn’t have to be complicated. Fitness content on social media may leave you thinking that you should only work out at specific times, use certain weights and incorporate an ever-rotating assortment of moves — but to reap the full benefits of building muscle, you can actually keep things surprisingly simple.
The Physical Activity Guidelines for Americans recommends at least two days of resistance training, aka strength training, for adults each week as part of their workout routines. And those two days need only include six moves, Adrian Chavez, Ph.D., nutrition and health coach, tells TODAY.com.
It’s often the most advanced fitness routines that generate the most buzz online. And while having lots of different strength moves in your arsenal can stave off boredom at the gym, it’s not usually necessary, Chavez explains. Sticking to the basics and staying consistent will give you the most bang for your buck, he adds.
The Most Efficient Strength-Training Moves
The six moves Chavez says are most efficient for improving health and body composition are:
“Those movements cover all of the (major) muscle groups of the body,” Chavez says. “I wouldn’t necessarily say these are the only six movements that you need, but those are the ones that are going to work the largest amount of muscle in each movement.”
Building muscle through strength training can boost longevity, a mood, bone density and more.
It’s also a key factor to improving metabolic health, Chavez points out. Muscle burns calories, even while you’re at rest. So, the more muscle you have, the more calories you’ll burn.
If you’re after efficient results, focusing on these six movements that target the body’s largest muscle groups will get you there since these muscles require the most energy to function.
Which Muscles Does Each Move Target?
The overhead press primarily targets the shoulders, says Chavez. It also works the triceps, the trapezius muscles in your upper back and the core.
Perform a chest press when you’re looking to strengthen your pectoralis muscles, the two largest in the chest. These muscles are responsible for lifting, rotating and pushing.
By including a back row in your strength training routine, you’ll be working your upper back and biceps, says Chavez.
The overhead pull-down or pull-up will strengthen your latissimus dorsi muscles (lats), which extend from the lower back to the armpit. Chavez says you’ll be engaging your biceps, too.
Squats work the quadricep muscles (quads) in the thighs, hamstrings and glutes, says Chavez. They’ll also engage your core, since squats require stability.
Include deadlifts in your routine to challenge your quad muscles in the thigh, hamstrings, glutes and lower back, says Chavez. You can choose between the regular deadlift and the Romanian deadlift, or incorporate both into your workout.
Benefits of a Consistent Strength Training Routine
Studies show that consistency when strength training, rather than the complexity of your workout plan, is what makes the biggest difference for health. Any kind of resistance training compared to none at all improve sstrength, muscle function and endurance regardless of intensity, equipment type and variation, research shows.
These six moves are not the only effective workouts for improving strength and altering body composition, but if you were to stick only to these six, you’d be in great shape, he explains.
Regular strength training will not only improve your physique but also your quality of life. “When you do a deadlift, that’s like picking up your kid,” Chavez says, comparing pull-ups to playing with them on the monkey bars.
“Carrying groceries, moving furniture, all of those things become a lot easier when you build some strength. And … these six movements cover all of the major muscle groups, so that will translate into really changing the way that you experience life,” he adds.
How to Add Variation
Once you’ve committed to a training plan you’ll use again and again, you may also want to mix things up, Chavez says.
To avoid boredom or to add an additional challenge, most of the six moves have variations.
For example, narrow-stance squats isolate the quads. Or you can change the grip during bicep curls to also target the forearms. “Learning slight variations to these primary movements is how you really build out a good routine,” he says.
An ideal workout program includes strength training at least two times a week and additional sessions with a type of cardio you enjoy. Chavez plays basketball, runs and rides his bike in between strength training sessions. He also suggests walking, swimming or rowing.
