Lesson 1: Why Strength Training Matters at Any Age

Why This Lesson Comes First

Strength training means making your muscles work against resistance. The resistance can be your own body weight, a dumbbell, a resistance band, a machine or a heavy bag of shopping. You do not need a gym, special clothes or any experience to begin.

This lesson covers three things you should know before you lift anything:

1. What the UK guidance asks adults to do.
2. Whether you should speak to your GP first.
3. Why having a qualified coach check your technique in person is worth it.

What the UK Guidance Says

The four UK Chief Medical Officers (CMOs) publish the official physical activity guidelines for England, Scotland, Wales and Northern Ireland. The guidelines were last updated in July 2026. The update reviewed the newer evidence but kept the same weekly targets as the 2019 edition.

For adults aged 19 to 64, the guidance says:

• Do activities that develop or maintain strength in the major muscle groups on at least 2 days a week.
• The NHS lists those major muscle groups as legs, hips, back, abdomen, chest, shoulders and arms.
• Any strengthening activity is better than none.
• Alongside this, aim for at least 150 minutes of moderate activity (such as brisk walking) or 75 minutes of vigorous activity (such as running) each week, and cut down on long periods of sitting.

For older adults (65 and over), the guidance says to do activities that improve or maintain muscle strength, balance and flexibility on at least 2 days a week.

Example: Priya works at a desk all week and does no strength work. If she does one short full-body session on Tuesday and another on Saturday, she meets the strengthening part of the guidance.

What Counts as Strengthening Activity

Strength work is not only lifting weights in a gym. The official examples include:

• Bodyweight exercises such as push-ups and sit-ups
• Free weights (dumbbells) and resistance machines
• Resistance bands
• Heavy gardening, such as digging and shovelling
• Climbing stairs and carrying children
• Yoga, Pilates and tai chi

Do this now: Write down any activity from the list above that you already do each week. That is your starting point.

Why It Matters at Any Age

The guidance stresses strength because it underpins everyday physical function: getting up from a chair, carrying shopping, climbing stairs and staying steady on your feet. Some points to keep in mind:

• Young and middle-aged adults build strength that they can maintain later in life.
• Older adults are advised to combine strength with balance work to stay steady and independent.
• People with no training history are covered too. The guidance says the biggest health gains come from moving from doing nothing to doing something.

Think of strength like savings in a bank account. The earlier and more regularly you pay in, the more you have to draw on later. It is also never too late to start paying in.

Step 1: Decide Whether to Check With Your GP

The NHS advises speaking to your GP before you start if you have not exercised for some time, or if you have medical conditions or concerns. Use this checklist. If you answer yes to any item, book a GP appointment before your first session:

• Do you have a heart, lung, joint, bone or other long-term health condition?
• Are you taking regular medication, including weight-loss medication?
• Have you had recent surgery or an injury that is still healing?
• Are you pregnant or have you recently given birth?
• Have you not exercised for a long time?
• Do you get chest pain, dizziness or unusual breathlessness when you exert yourself?

If you answered no to all of them, you can usually start gently. If you get chest pain, dizziness or unusual breathlessness while training, stop and get medical advice.

Do this now: Go through the checklist and write down your answers.

Step 2: Plan to Have Your Technique Checked in Person

You cannot see yourself from the side while you move, and a beginner often cannot feel a fault. Common examples are knees caving inwards or the lower back rounding. A qualified coach watching you in person can:

1. Spot faults you cannot see or feel.
2. Correct them before they become habits.
3. Adjust exercises to suit your body, any health condition and your equipment.
4. Show you a safe starting load.

Videos and apps are useful, but they cannot watch you. In the UK, look for a coach with a recognised Level 3 personal training qualification. You can check whether a trainer is registered on the CIMSPA (Chartered Institute for the Management of Sport and Physical Activity) register. Registration is voluntary, but it shows professional standing. Even one or two sessions to check your technique are worthwhile.

Do this now: Find one qualified coach or gym instructor near you, or one who works online with live video, and note their details.

Step 3: Commit to Two Days

1. Choose two non-consecutive days each week, for example Monday and Thursday.
2. Put them in your calendar like appointments.
3. Keep them even before you start following a full programme.

Key Takeaways

• The UK CMOs advise adults to do muscle-strengthening activity on at least 2 days a week, working all the major muscle groups.
• Adults aged 65 and over should work on strength, balance and flexibility on at least 2 days a week.
• Any strengthening activity is better than none, and everyday tasks such as heavy gardening count.
• Speak to your GP first if you have a health condition, take regular medication, or have not exercised for a long time.
• A qualified coach checking your technique in person catches faults you cannot see or feel.
