How to Start Exercising When You Have Not Done Any for Years

Starting to exercise after years away from it is not really a fitness problem. It is a starting problem. Most beginners are perfectly capable of walking briskly for twenty minutes or doing a few bodyweight exercises. What trips them up is starting too hard, feeling awful, missing a week and deciding they are “not a gym person”.

This guide takes the opposite approach. It begins with very little, builds slowly and focuses on making exercise a normal part of the week rather than a dramatic new identity. It is designed for complete beginners, people returning after a long break and anyone who has started and stopped more times than they would like to admit.

Here at FlyJanuary.org we write a lot about fresh starts, and exercise is the classic January resolution that fades by February. The aim here is to build something that lasts until summer and beyond.

How much exercise you are aiming for

It helps to know where you are heading, even if you will not get there for a while. The NHS guidelines for adults suggest:

• At least 150 minutes of moderate-intensity activity a week, such as brisk walking or cycling, or 75 minutes of vigorous activity, such as running, or a mix of the two.
• Strength exercises on at least two days a week that work the major muscle groups.
• Reducing long periods of sitting where you can.

You can read the full guidance on the NHS exercise pages. The key point for a beginner is that this is a target to build towards, not a starting point. Any activity is better than none, and the biggest benefits tend to come from going from nothing to something.

You do not have to meet the guidelines in week one. Your first job is to become someone who exercises a little, regularly. The amount can grow later.

Before you start

A few minutes of preparation saves a lot of frustration.

Check in on your health

Most people can start gentle activity such as walking without any problem. If you have a heart or lung condition, diabetes, joint problems, are pregnant, or have ever had chest pain, fainting or dizziness during activity, speak to a GP or practice nurse first. It is also worth asking if you are simply unsure.

Sort out the basics

You do not need special kit. Comfortable clothes and supportive trainers are enough for walking and home exercise. If you plan to run, it may be worth having your trainers fitted at a specialist shop, but that can wait until you know you are sticking with it.

Pick a time, not just an intention

“I will exercise more” rarely survives a busy week. “I will walk for twenty minutes at 12.30 on Monday, Wednesday and Friday” has a much better chance. Put it in your calendar like any other appointment.

Choose an activity you might actually enjoy

The best exercise is the one you will keep doing. Some options that suit beginners:

Activity	Why it suits beginners	Things to know
Brisk walking	Free, low impact, easy to fit in	Aim for a pace where you can talk but not sing
Swimming	Kind on joints, works the whole body	Check local pool times and lane sessions
Cycling	Builds fitness without heavy impact	Start on quiet routes or a static bike
Beginner running	Efficient and flexible	Use a walk-run programme rather than running continuously
Bodyweight strength	Can be done at home in ten minutes	Focus on form before adding repetitions
Group classes	Structure and social motivation	Tell the instructor you are new

If running appeals, the NHS Couch to 5K programme is a well-known free option that builds from short running intervals over several weeks.

A gentle four-week starter plan

Here is a worked example for someone starting from very little. Adjust the numbers to suit you. If a week feels too hard, repeat it rather than moving on.

Week	Walking	Strength	Weekly total (approx.)
1	3 walks of 15 minutes	1 session of 10 minutes	55 minutes
2	4 walks of 20 minutes	2 sessions of 10 minutes	100 minutes
3	4 walks of 25 minutes	2 sessions of 15 minutes	130 minutes
4	5 walks of 25 minutes	2 sessions of 15 minutes	155 minutes

By week four, this example plan reaches roughly the 150-minute guideline for moderate activity, plus two strength sessions, without any single day being demanding.

A simple strength session

You can do this at home with no equipment:

1. Sit-to-stand from a chair, 8 to 10 times.
2. Wall press-ups, 8 to 10 times.
3. Step-ups on the bottom stair, 8 to 10 each leg, holding the banister.
4. Glute bridges lying on your back, 8 to 10 times.
5. Standing calf raises, holding a chair, 10 to 12 times.

Rest for a minute and repeat the circuit once or twice. Move slowly and with control. If anything causes sharp pain, stop.

How hard should it feel?

Beginners often either take it far too easy or push until they feel ill. A simple guide is the talk test:

• Moderate intensity: you are breathing faster and feel warmer, but can still hold a conversation.
• Vigorous intensity: you can only say a few words before needing to pause for breath.

For the first few weeks, moderate is plenty. Feeling pleasantly tired afterwards is good. Feeling wrecked for the rest of the day is a sign to scale back.

Making the habit stick

Starting is the easy part. Keeping going through February rain and a busy spring is the real challenge.

• Lower the bar on bad days. If you cannot face twenty minutes, do five. Keeping the habit alive matters more than any single session.
• Attach it to something you already do. A walk straight after dropping the children at school or a strength circuit while the kettle boils is easier to remember.
• Track it simply. A tick on a calendar is enough. Seeing a run of ticks is motivating.
• Exercise with someone. A friend, a club or a class gives you a reason to turn up.
• Plan for winter. Have an indoor option ready for dark, wet evenings so the weather does not end the habit.

Common beginner mistakes

A few patterns catch out many people who start enthusiastically:

1. Doing too much in the first week. Soreness and exhaustion make it hard to continue.
2. Expecting quick visible results. Fitness and energy often improve before appearance changes, so judge progress by how you feel and what you can do.
3. Relying on motivation. Motivation comes and goes. A fixed time and a low minimum carry you through.
4. All or nothing thinking. Missing a week is not failure. Just restart at the previous week of the plan.
5. Ignoring rest. Muscles adapt between sessions, so rest days are part of the plan.

The benefits beyond fitness

Regular activity is widely recommended not just for physical health but for general wellbeing, sleep and mood. Many people find a daily walk is one of the simplest ways to feel better in winter, especially when it gets them out in daylight. If the darker months tend to drag you down, our article on beating the January blues explains how movement fits alongside other basics.

Start small, be consistent and let the amount grow. Four weeks from now, you could be someone who exercises regularly without it feeling like a battle. Browse more practical guides in our wellness section.

Frequently asked questions

How much exercise should a beginner do?

Start with less than you think you can manage, such as 10 to 20 minutes of brisk walking most days, and build gradually. The NHS suggests adults work towards at least 150 minutes of moderate activity a week plus strength exercises on two days, but that is a goal to reach over time.

Should I see a doctor before starting to exercise?

Most people can safely start gentle activity such as walking. If you have a health condition, are pregnant, have had chest pain or dizziness, or have not been active for a long time and are unsure, it is sensible to check with a GP or practice nurse first.

Is it normal to ache after starting exercise?

Mild muscle soreness a day or two after a new activity is common and usually fades within a few days. Sharp pain, joint pain or pain that gets worse is different, and you should stop and seek advice rather than push through it.
