Fitness Through Life

In short: Fitness needs change across childhood, adulthood, pregnancy and older age. Use age-appropriate public-health guidance as a direction, not a personalised prescription. Prioritise enjoyable movement, strength and practical function, adapt for disability or illness, and seek relevant advice when symptoms, pregnancy circumstances or medical needs affect what is suitable.

This chapter of the ultimate guide to fitness looks at changing needs without treating age as a fixed limit. Your health, confidence, interests and circumstances matter alongside the number of birthdays you have had.

Why should your approach to fitness change through life?

Your approach should change because development, health, recovery, responsibilities and the activities that matter to you change.

A child's active play, an adult's lunchtime walk and an older person's balance practice may all support health, but they do not serve identical purposes. Children are developing movement skills and confidence. Adults may be fitting activity around work and caring. Later-life activity may place particular value on independence and fall prevention.

Changes are not always age-related. An injury, new medication, fluctuating condition or loss of access to a local facility can matter more than entering a new decade. A routine should be flexible enough to respond without becoming an all-or-nothing test.

Keep useful questions in view: what would you like to do more comfortably, what do you enjoy, and what support would make participation easier? Carrying shopping, joining friends outdoors or getting up from a chair can be meaningful outcomes.

Food and recovery needs also deserve attention throughout life. Our fitness nutrition guide offers general support without assuming everyone needs the same meals or sports products.

What physical activity guidance applies to children and young people?

Children and young people aged five to eighteen should generally aim for an average of at least sixty minutes of moderate or vigorous activity a day across the week.

This is the NHS guidance for children and young people, and it is separate from adult weekly targets. Activity should include varied types and intensities to develop movement skills, muscles and bones, with long periods of sitting interrupted.

Activity can include playground games, walking or cycling to school, dance, swimming, PE and sport. It does not need to be one continuous formal workout. Enjoyment, safe supervision and opportunities to try different movements are more useful than imposing an adult gym routine.

Avoid framing movement as punishment for eating or as a way to change a child's body shape. Praise skills, confidence, cooperation and enjoyment instead. A child who dislikes competitive sport may enjoy climbing, active games or dancing at home.

Disabled children may need different formats and targets; the NHS page includes specific guidance. Adapt participation to the child's abilities and needs rather than using the general target as a pass-or-fail test. Children under five have separate guidance and should not simply inherit school-age targets.

What should adults aim towards, and how should beginners use the targets?

Adults should work towards a mixture of aerobic activity and strengthening, starting from an amount appropriate to their current circumstances.

The NHS adult activity guidance recommends at least 150 minutes of moderate activity or 75 minutes of vigorous activity weekly, or an equivalent combination. It also recommends strengthening all major muscle groups on at least two days a week and reducing prolonged sitting.

These are population aims, not a tailored prescription. A beginner does not need to complete the full target immediately. Start with manageable activity and build according to comfort, function and any clinical advice. Vigorous exercise is not compulsory.

Moderate effort generally makes you breathe faster while still being able to talk, though not sing. The same activity can feel different to different people. A pace that is gentle for one person may be demanding for another.

A mixed week might include walking, cycling or swimming alongside suitable strength work. Our strength-training chapter explains accessible starting options without assuming access to a gym.

How should you approach exercise during pregnancy?

Use NHS pregnancy-specific guidance and advice relevant to your pregnancy rather than assuming every activity is suitable for everyone.

The NHS exercise in pregnancy guidance supports staying active and starting new activity gently. It describes an aim of 150 minutes of moderate activity across the week, including strengthening, while recognising that doing what you can is worthwhile.

This is not blanket clearance for every pregnancy or exercise. Existing conditions, pregnancy complications, symptoms and previous activity affect what is suitable. Speak with your midwife or maternity team about relevant precautions, especially if you have a health condition, have been advised to restrict activity or are unsure about a particular sport.

Comfortable walking, swimming and appropriately adapted classes may be options. Tell an instructor that you are pregnant and check that they can provide suitable adaptations. Avoid activities involving a substantial risk of collision or falling, and follow NHS advice about positions and activities to avoid.

Stop and contact your maternity team for concerning symptoms such as vaginal bleeding, fluid leakage, painful contractions, dizziness or feeling unwell. Severe breathlessness, chest pain or collapse requires urgent help. Pregnancy is not the time to ignore symptoms to maintain a streak.

How should you return to activity after giving birth?

Return gradually according to your birth, recovery, symptoms and advice from your maternity or healthcare team.

Recovery after birth varies. A straightforward delivery, a caesarean birth, significant tearing, pelvic floor symptoms and other complications can lead to different needs. Caring for a newborn and disrupted sleep also affect capacity, even when someone feels keen to exercise.

Gentle movement may be appropriate early for some people, but it should not be turned into a deadline. Discuss suitable pelvic floor exercises and progression with your midwife or relevant clinician. Seek help for persistent pain, leakage, pelvic heaviness or symptoms that worsen with activity.

A postnatal check is an opportunity to discuss recovery and next steps, not proof that every type of exercise is automatically suitable. Return to running, jumping or demanding lifting should reflect symptoms, previous activity and individual advice.

Keep goals practical: a comfortable short walk, rebuilding confidence or finding a few minutes for yourself. Sleep, meals and support may need priority over formal sessions. Our recovery and injury-prevention information explains why adaptation is part of sensible exercise, not a failure to progress.

What matters during midlife and menopause?

During midlife, maintain a flexible mixture of aerobic activity and strength work while adapting to symptoms, health changes and competing demands.

Midlife does not require abandoning challenging exercise, nor does it require adopting a harder programme. Some people feel stronger and more confident than before; others are managing pain, disrupted sleep, caring responsibilities or changes in mood and energy.

During perimenopause and menopause, symptoms can affect participation. Choosing cooler environments, adjusting session timing or using shorter sessions may help make activity more comfortable. Exercise can support general wellbeing, but it is not a substitute for assessment or treatment of troublesome symptoms.

Strength work can remain relevant to everyday function, while walking, swimming, cycling and other enjoyable activities provide different ways to stay active. Include movement that feels worthwhile to you rather than pursuing a routine solely because it is marketed for a particular age.

Persistent fatigue, unexplained bleeding, new pain or other concerning changes should not automatically be attributed to age or menopause. Seek appropriate advice rather than trying to train through them.

What should older adults prioritise?

Older adults should combine regular activity with strength, balance and flexibility work on at least two days a week, adapted to their abilities.

The NHS guidance for adults aged 65 and over recommends daily activity, including light movement, and reducing prolonged sitting. It also gives an aerobic aim of 150 minutes of moderate activity weekly, or appropriate vigorous activity for those already active.

Strength, balance and flexibility deserve explicit attention rather than assuming walking covers everything. Suitable activities might include supported balance practice, controlled chair rises and comfortable flexibility movements. The exact choice should reflect health, mobility and fall risk.

If you have fallen or are worried about falling, ask about appropriate support rather than attempting difficult balance tasks alone. A stable support, clear space and suitable supervision can make participation more accessible.

Do not assume that later life means only gentle exercise. Equally, do not compare yourself with unusually athletic examples online. Progress is individual. Our mobility and balance chapter offers ways to think about practical movement and confidence.

How can fitness adapt to disability, illness and changing access?

Adapt the activity, environment and expectations so that participation reflects your needs rather than a standardised ideal.

Seated exercise, wheelchair-based activity, supported standing, water-based movement and shorter sessions may all offer useful options. The appropriate choice depends on the person: one adaptation does not suit everyone with the same diagnosis.

Examples of adapting activity across changing circumstances

Circumstance	Possible adaptation	What to check
Balance concerns	Use stable support or supervised sessions	Fall risk and access to assessment
Limited standing tolerance	Explore seated or supported activity	Comfort, positioning and suitable instruction
Variable energy	Adjust timing, length and recovery	Whether condition-specific pacing advice is needed
Limited transport or funds	Consider home-based or local options	Space, safety and accessibility

Some conditions require specific precautions or pacing rather than standard exercise progression. If activity causes a delayed, disproportionate worsening of symptoms, seek advice. More effort is not automatically the answer.

Our fitness resources can help you explore formats. Ask providers about step-free access, accessible changing facilities, communication needs and instructor experience before attending.

Key takeaways

• Children's activity guidance is separate from adult targets.
• Adult targets are population aims, not individual starting prescriptions.
• Pregnancy and postnatal exercise need relevant guidance and symptom awareness.
• Older adults should include strength, balance and flexibility at least twice weekly.
• Adaptations support participation without guilt or comparison.

Frequently asked questions

Is it too late to start exercising in older age?

No. Appropriate activity can still be worthwhile. Begin at a suitable level and discuss your plans with a GP if you have been inactive for some time or have medical conditions or concerns.

Can children use the adult 150-minute weekly target?

No. Children aged five to eighteen generally have a separate average sixty-minute daily target across the week, with varied activity. Younger children and disabled children also have specific guidance.

Can everyone continue their normal workout during pregnancy?

No single answer covers every pregnancy. Previous activity, symptoms, complications and the exercise itself matter. Follow NHS pregnancy guidance and discuss relevant concerns with your maternity team.

Does walking replace strength and balance work?

Walking is valuable, but it does not necessarily challenge strength, balance and flexibility enough on its own. Include suitable additional activities, particularly in later life.
