Starting Exercise at 45: A Safe 12-Week Plan

You are 45, the kids still need lifts everywhere, your knees click on the stairs and the last time you trained properly was before the first baby. Part of you thinks the ship has sailed. It has not. Starting exercise at 45 is one of the best decisions you can make, and in my experience people who start in their forties often do better than they did at 25, because they finally train with a bit of patience. I coach a lot of mums and dads in this exact spot in Archway, and this is the plan I give them.

Is 45 too late? The honest answer

No. Your body still responds to training at 45, at 55 and well beyond. What changes is how you should start. You recover a little slower, you probably have an old niggle or two, and your time is squeezed by work and family. So the plan has to be shorter, kinder on the joints and more consistent than the “all or nothing” approach you might have tried before.

The NHS lists a long set of health benefits of exercise, including a lower risk of heart disease, stroke, type 2 diabetes and depression, plus better sleep, mood and energy. None of that has an age cut-off.

Before you start: a quick health check

If you have not exercised for a while, or you have a medical condition such as high blood pressure, a heart problem, diabetes, joint pain or a past injury, speak to your GP or a physio before you begin. The NHS physical activity guidelines for adults say exactly this. The NHS also recommends getting your blood pressure checked if you are 40 or over and have not had it checked for more than 5 years, so if that is you, book it in. It is quick and it gives you a starting point.

Women in their forties may also be going through perimenopause, which can affect sleep, joints and energy. If symptoms are getting in the way, talk to your GP. Strength training is still very worthwhile, and I have written more about perimenopause and strength training.

Starting exercise at 45: a 12-week plan

The NHS target for adults is 150 minutes of moderate activity a week plus muscle-strengthening work on at least 2 days. You do not need to hit that in week one. Build towards it.

Weeks 1 to 4: show up

• 2 strength sessions a week, 20 minutes each, at home or in a class.
• A 20-minute brisk walk on 3 other days. The school run or the walk to the station counts if you pick up the pace.
• Strength session: 2 rounds of 10 sit-to-stands from a chair, 8 push-ups against the kitchen worktop, 10 glute bridges, 20-second plank on your knees, 10 bent-over rows using two bags of shopping. Rest a minute between rounds.

The only goal for this month is attendance. Tick the sessions off on a calendar.

Weeks 5 to 8: build

• Go to 3 rounds of the strength session, or add a third 20-minute session.
• Swap sit-to-stands for squats without the chair, and worktop push-ups for push-ups on a low step.
• Stretch the walks to 30 minutes, with a few hills thrown in. Archway has plenty.

Weeks 9 to 12: add some load

• Pick up a light kettlebell or dumbbell and add goblet squats and deadlifts (3 sets of 8 to 10).
• Add one short burst of harder cardio a week, like 6 rounds of 30 seconds fast marching or cycling, 60 seconds easy.
• By now you should be close to the NHS weekly target without it feeling like a second job.

Five rules I give every 45-year-old beginner

1. Warm up every time. Five to eight minutes of marching, arm circles and slow squats. It matters more now than it did at 25.
2. Leave 2 reps in the tank. Finish each set feeling you could have done a couple more. That is enough to make progress without wrecking you.
3. Strength first, cardio second. From your forties onwards, keeping muscle and bone strong pays off for decades.
4. Protect sleep. A bad night means a lighter session, not a skipped week.
5. Pain is a stop sign. Normal muscle ache the next day is fine. Sharp pain, joint pain that gets worse, chest pain or dizziness means stop and get checked.

How long until you see results?

This is the question I get asked most. Most people I coach feel a difference in energy and sleep within 2 to 3 weeks. Strength usually improves noticeably in 4 to 6 weeks, because your nervous system learns the movements quickly. Visible changes in how clothes fit tend to take 8 to 12 weeks of consistent training and sensible eating, and they vary a lot from person to person. I go into more detail in how long it takes to see fitness results.

Where a bootcamp class fits

The biggest risk when starting exercise at 45 is not injury. It is drifting off after three weeks because life gets busy. A small group with a coach who knows your name fixes most of that. My SYP Built To Last strength class for over 35s was designed for exactly this: functional strength, joint-friendly options and no one shouting at you to do burpees until you are sick. Every exercise has an easier and harder version, so you start where you are. If you have been out of the game for years, my guide to starting exercise after years off is worth a read too.

FAQs

Is 45 too late to start exercising?

No. People of all ages get stronger, fitter and healthier with regular exercise. Start gently, build up over a few months and check with your GP first if you have a health condition or have been inactive for a long time.

How long does it take to see results when you start exercising at 45?

Most beginners notice better energy and sleep within a few weeks, strength gains in 4 to 6 weeks and changes in body shape after around 2 to 3 months of consistent training. It depends on how often you train, sleep, stress and food.

What is the best exercise to start with at 45?

A mix of brisk walking and simple strength training, like squats, push-ups, bridges and rows. Strength work is the part most people in their forties are missing, and it helps with posture, joints and everyday jobs like lifting kids and shopping.

How often should a 45-year-old work out?

Aim for strength training on 2 to 3 days a week and some moderate activity, like brisk walking, on most days. That lines up with the NHS guidelines and leaves room for recovery.
