Fit at 70: Seven Everyday Habits for Staying Active, Alert and Content

You do not have to feel sluggish and frail at 70. A few sensible everyday habits can help you remain impressively fit, alert and content.

Many people worry about getting older: less strength, more aches and pains, and a diminishing enjoyment of life. Yet this is a major misconception. Research has shown for years that the body can still be highly capable at 70 – provided it is not simply left to its own devices. Seven areas matter most, and small, consistent actions in them achieve more than any miracle pill.

Keep your body moving without overdoing it

At 70, exercise does not mean entering a marathon. The aim is regular activity suited to your abilities: movement that is kind to the joints while challenging the muscles rather than damaging them. Doctors often refer to “everyday activity” – and that can begin right outside your front door.

Around 4,500 steps a day are already enough for most people aged 70 and over to maintain their circulation, muscles and mobility.

If you have hardly been active so far, it is best to begin with very manageable steps: brief walks, doing a few journeys on foot rather than by car, taking the stairs instead of the lift, and gradually extending the time spent moving. A fitness tracker or step-counting app can provide motivation and help you keep the 4,500-step target in sight.

Gentle sports that are ideal at 70

• Walking and hiking: support the heart and circulation while working balance and leg muscles.
• Gentle swimming: takes pressure off the joints and strengthens the back and shoulders.
• Aqua cycling or water aerobics: water reduces the load on the body, makes movements easier and lowers the risk of falls.
• Cycling (indoors or outdoors): particularly suitable for anyone with knee or hip problems.

There are also activities many people do not even regard as exercise: gardening, vacuuming, cleaning windows and carrying out small repairs. All of these challenge the muscles and coordination while also keeping the home in good order.

Being active outdoors brings sunlight as well as movement. This stimulates vitamin D production, which in turn supports the bones and immune system. This effect makes a real difference in later life.

Keep an eye on weight – neither too high nor too low

At 70, many people struggle either with excess weight or with the opposite problem: unintended weight loss, declining muscle mass and a feeling of weakness. Both put strain on the body and increase the risk of illness.

Doctors use the body mass index (BMI) as a general guide. It is calculated by dividing body weight in kilograms by height in metres squared.

BMI value	Assessment
below 18.5	significant deficiency, with a risk of weakness and falls
18.5 – 25	normal range
25 – 30	overweight
30 – 40	obesity
40 – 50	severe obesity
above 50	extreme obesity

If the figure is clearly above 25, changing your diet is worthwhile. Carrying too many kilos does not only make you tired and less mobile; it also raises the risk of diabetes, joint wear and tear, stroke and heart attack.

People who lose a few kilos often sleep better, find stairs easier to climb and feel surprisingly more confident.

What a practical diet after 70 can look like

• Plenty of vegetables and fruit: provide vitamins, fibre and plant compounds.
• Enough protein: for example from eggs, dairy products, pulses, fish or lean meat – essential for maintaining muscle.
• Wholegrains instead of refined flour: keep you full for longer and stabilise blood sugar.
• Little sugar and few processed foods: reduce hidden calories and additives.

Conversely, anyone who has lost a great deal of weight or is becoming noticeably weaker should speak to their GP to establish whether they are malnourished. The body may then need specifically increased calories and protein, potentially with the help of nutritional drinks.

Train the brain like a muscle

Being fit at 70 is about more than flexible knees and strong legs. The brain needs a challenge too. Using your mind builds mental reserves – this cannot reliably prevent dementia, but in many cases it can delay cognitive decline.

Regular thinking, learning and puzzle-solving work like fitness training for nerve cells.

Any activity that genuinely stimulates rather than merely provides passive entertainment can help:

• Reading novels, non-fiction books, newspapers and magazines
• Visiting museums, theatres and concerts
• Completing crosswords, Sudoku and logic puzzles
• Playing board games and card games with others
• Using simple learning apps or tablet games that test memory and reaction speed

Learning something entirely new can be especially effective, whether that is a foreign language, a musical instrument or using a smartphone confidently. It compels the brain to form new connections, which is precisely what mental fitness depends on.

Social contact as protection against loneliness

People who feel lonely over a long period age faster, both physically and emotionally. A positive mood, reliable surroundings and regular contact with others work almost like medicine against low spirits and lack of motivation.

Useful options include:

• Neighbourhood cafés, social groups for older people or sports groups
• Clubs, choirs and adult education courses
• Regular meetings with friends and acquaintances

Family is just as important an anchor. Shared meals, game nights with grandchildren, short outings or simply a long telephone conversation can transform the whole day. Those who make themselves useful – by looking after children, helping with a house move or assisting with paperwork, for example – often immediately feel: “I am needed.”

See your GP regularly – not only when there is a problem

Many health issues develop gradually: high blood pressure, diabetes, heart failure and kidney disease. Initially, they cause barely any symptoms, yet they may already be doing damage inside the body. Anyone aiming to stay fit at 70 should therefore rely on check-ups rather than chance.

An annual health check and regular appointments with your GP provide reassurance and improve the chances of detecting illness early.

This can include blood-pressure measurements, blood tests, checks of the heart and kidneys, vaccine boosters and, depending on your medical history, further screening. It is important to follow treatment advice properly: take tablets regularly, use prescribed aids and accept rehabilitation services.

Commitment and volunteering: purpose gives strength

Many people who have recently retired describe a void: suddenly, there is no structure, no colleagues and no clearly defined tasks. Finding a meaningful occupation brings benefits on several levels – socially, mentally and emotionally.

Voluntary work can range from helping children with homework and visiting residents in care homes to supporting sports clubs. Older people bring experience, calmness, often practical skills and life wisdom. These qualities are needed – and receiving that feedback benefits their own wellbeing in return.

Do not forget enjoyment: pleasure is a health factor

Nobody has to “hold back” at 70 simply because working life has ended. On the contrary, this is the time to revive old hobbies or try new ones. Painting, singing, dancing, photography, travelling, model-making, camping or cooking: anything is suitable if it feels good and is realistically achievable.

People who regularly do something simply because they enjoy it protect themselves from depression better than through any amount of self-help reading.

The combined effect is interesting. Someone taking part in a dance group, for instance, brings together exercise, social contact, music and enjoyment. Such combinations are particularly powerful. The same applies to walking groups, choir rehearsals and theatre projects for older people.

A simple weekly plan can be helpful: set days for exercise, meeting people, hobbies and voluntary work. This creates structure without making the diary feel overcrowded. And from many small decisions – a walk today, a board game tomorrow, a GP appointment the day after – there gradually emerges what everyone wants at 70: a life that feels remarkably young despite the wrinkles.
