Physical Activity and Exercise: A GP Guide
Regular physical activity is one of the most powerful things you can do for your health. It lowers the risk of heart disease, stroke, type 2 diabetes, some cancers, depression and dementia.
You do not need a gym membership or to run marathons. Brisk walking, cycling, gardening and carrying shopping all count, and any increase from your current level brings benefit.
This guide explains how much activity adults need, why strength matters, and how to start safely.
These articles are intended as educational sources, not diagnostic nor taking place of a proper medical assessment. If you need help, please book an appointment with one of our GP’s.
How much activity do adults need?
The UK Chief Medical Officers recommend that adults aged 19 to 64:
- do at least 150 minutes of moderate activity a week, or 75 minutes of vigorous activity, or a mix of both
- do muscle-strengthening activity on at least 2 days a week
- reduce long periods of sitting
Adults over 65 should follow the same advice where possible, and also include activities that improve balance and flexibility to reduce the risk of falls.
Moderate or vigorous?
Moderate activity raises your heart rate and makes you breathe faster, but you can still talk. Vigorous activity makes you breathe hard, and you can only say a few words without pausing.
As a rough guide, 1 minute of vigorous activity gives similar benefit to 2 minutes of moderate activity.
Types of activity
A balanced week usually includes a mix of:
Brisk walking
Easy to start, free, and counts as moderate activity.
Cycling and swimming
Good for fitness and gentle on the joints.
Strength training
Weights, resistance bands or bodyweight exercises such as squats.
Balance and flexibility
Yoga, Pilates and tai chi, especially as you get older.
Everyday activity
Gardening, housework, taking the stairs and active travel.
Sport and classes
Team sports, dance and group classes add a social element.
The benefits of regular activity
Being physically active helps to:
- lower blood pressure and improve cholesterol
- improve blood sugar control and insulin sensitivity
- maintain a healthy weight
- improve sleep, mood and energy
- reduce the risk of falls and fractures
The biggest gains come when someone who is inactive becomes a little more active.
Why strength matters
Muscle strength naturally declines with age. Strength training helps to:
- maintain muscle and bone strength
- support joints and reduce back pain
- improve blood sugar control
- preserve independence in later life
Strength work is especially important when losing weight, including with GLP-1 medicines, to help protect muscle.
Getting started safely
If you are new to exercise or returning after a break:
- start with short sessions, such as 10 minutes, and build up gradually
- choose activities you enjoy and can fit into your week
- warm up before and cool down after
- expect some muscle soreness at first; this usually settles within a few days
Consistency matters more than intensity. Regular moderate activity is better than occasional intense sessions.
Fitting activity into a busy life
Practical ideas include:
- walking or cycling for part of your commute
- taking a 10-minute walk after meals
- doing bodyweight exercises at home
- standing or walking during phone calls
Short bouts of activity add up across the day and all count towards your weekly total.
Activity with a long-term condition
Physical activity is safe and beneficial for most long-term conditions, including:
- high blood pressure and heart disease
- type 2 diabetes
- asthma and COPD
- arthritis and back pain
- anxiety and depression
It is sensible to speak to a GP first if you have a heart or lung condition, or if you have been advised to limit activity. See our guides to asthma and COPD.
When to stop and seek advice
Stop exercising and seek medical advice if you develop:
- chest pain or tightness
- severe breathlessness
- dizziness or feeling faint
- palpitations
If symptoms are severe or do not settle with rest, call 999.
Frequently asked questions
How much exercise should I do each week?
Adults should aim for at least 150 minutes of moderate activity or 75 minutes of vigorous activity a week, plus muscle-strengthening activity on at least 2 days.
Does walking count as exercise?
Yes. Brisk walking counts as moderate activity and is one of the easiest ways to become more active.
Do I need to do it all at once?
No. Activity can be spread across the week and the day. Short bouts of activity all count towards your total.
Is it safe to exercise with a heart or lung condition?
For most people it is safe and beneficial. Speak to a GP first if you have a heart or lung condition, or have been told to limit activity, so you can agree a safe starting point.
Will exercise help me lose weight?
Activity helps with weight loss and is especially important for keeping weight off. It works best combined with changes to diet.
