How to Start Exercising When You're Completely Out of Shape

You Don't Need to Be Fit to Start

You've thought about it a hundred times. Maybe you've even bought runners that are still sitting in the box. But every time you look at a workout plan or a fitness class, it feels like it was made for someone who already exercises — and that's not you.

You're not alone. According to the Australian Institute of Health and Welfare, fewer than one in four Australian adults meet both the aerobic and strength components of the national physical activity guidelines. And physical inactivity is the ninth leading preventable cause of ill health and premature death in Australia.

But here's what most fitness content gets wrong: it assumes you already have a baseline. This guide doesn't. Whether you haven't moved in years, have never exercised, or just don't know where to begin — this is your starting point.

Forget the Guidelines (For Now)

The Australian Physical Activity Guidelines recommend adults get 150 to 300 minutes of moderate-intensity activity per week, plus muscle-strengthening activities on at least two days. That's a solid target — but if you're starting from zero, it can feel impossibly far away.

The guidelines themselves actually say something important that often gets buried: doing any physical activity is better than doing none. That's not a consolation prize. It's the whole point. Even small amounts of movement reduce your risk of chronic disease, improve mood, and help you sleep better.

So don't aim for 150 minutes. Aim for five.

Start With Walking — Seriously

Walking is the most underrated form of exercise in Australia. It requires no equipment, no membership, no coordination, and no fitness level. You can do it from your front door.

Start with a five-minute walk. Not a power walk, not a brisk march — just a walk. Around the block. To the letterbox and back. Down the street to grab a coffee. It doesn't matter where. What matters is that you did it.

Do that three or four times in your first week. The following week, try seven minutes. Then ten. You're not training for anything. You're building a habit — and small habits compound faster than you'd expect.

If walking feels too easy, that's perfect. You want it to feel easy. The moment exercise feels punishing, you stop doing it. The goal right now is to keep showing up.

A Simple Week-by-Week Progression

There's no rush here, and these aren't rules. If a week feels too fast, repeat it. If it feels too slow, move ahead. Listen to how your body responds.

Weeks 1–2: Walk for 5–10 minutes, three to four days a week. Keep the pace comfortable — you should be able to hold a conversation without getting breathless.

Weeks 3–4: Extend to 15–20 minutes. Try walking at a slightly brisker pace for a minute or two in the middle, then ease back. Starting slow is a feature, not a bug.

Weeks 5–6: Aim for 20–30 minutes, four to five days. You might notice you're sleeping a bit better or feeling less sluggish in the afternoons.

Weeks 7–8: Start exploring variety. Walk a different route. Try a gentle stretch after your walk. Consider a local walking group if you'd like some company.

Low-Impact Options Beyond Walking

Once you've built a basic walking habit and feel ready to try something new, there are plenty of activities that are gentle on your body while still getting you moving.

Swimming and water-based exercise are brilliant if you carry extra weight or have joint pain. The water supports your body, so movements that might be uncomfortable on land feel much easier in a pool. Most local aquatic centres run beginner-friendly water aerobics classes. Find pools and aquatic centres near you.

Cycling — even on a stationary bike — is easy on the knees and lets you control the intensity. You don't need to ride far or fast. Ten minutes on a flat path counts. And e-bikes are a legitimate option if hills are a barrier.

Gentle yoga or tai chi build flexibility and balance without requiring any cardio fitness. Many community centres and libraries offer free or low-cost beginner sessions — search for fitness training groups near you to see what's available locally.

Lawn bowls might not be the first thing that comes to mind, but it gets you outdoors, on your feet, and socialising — with zero fitness barrier to entry. Most clubs welcome beginners with open arms and barefoot bowls sessions are a relaxed way to try it.

The Mental Hurdle Is Real

Let's talk about the part that no workout plan addresses: feeling like you don't belong.

Walking into a gym when you're unfit takes courage. Showing up to a group class when everyone else seems to know what they're doing is intimidating. And scrolling through fitness content full of toned bodies and intense workouts can make you feel like exercise isn't for people who look like you.

It is. Full stop.

If the gym feels too exposed, don't go to the gym. Walk your neighbourhood. Exercise in your lounge room. Find a quiet park. There's no rule that says physical activity has to happen in a fitness facility, and exercising in green spaces has its own health benefits.

If group settings feel uncomfortable, start solo. Once you've built some confidence and routine, you might find that a beginner-friendly group is less scary than you imagined — and far more welcoming.

Find Something You Actually Enjoy

This is the part that matters most, and it's the part most beginner guides skip over. Sustainable exercise isn't about willpower. It's about finding an activity you don't dread.

If you hate running, don't run. If the gym bores you, skip it. If you loved playing tennis as a kid, try picking it up again. If you've always been curious about pickleball, now's the time.

The Australian guidelines don't care how you move — they care that you move. Gardening counts. Dancing in your kitchen counts. Playing with your kids at the park counts. Every minute of movement adds up.

Browse activities near you and filter by what interests you. You might be surprised at what's running in your area — from social badminton to walking netball to community dance classes.

What About Strength Training?

The national guidelines recommend muscle-strengthening activities on at least two days per week, and 73% of Australian adults don't meet this target. But strength training doesn't mean lifting heavy barbells in a gym.

At the beginner level, your own body weight is enough. Standing up from a chair without using your hands is a squat. Pushing against a wall is a push-up. Carrying your shopping bags from the car is a loaded carry. These all count.

Once you've been walking regularly for a few weeks, try adding two or three bodyweight movements after your walk — even just a minute of each. Wall push-ups, standing calf raises, sitting down and standing up from a chair ten times. That's strength training. It doesn't need to be more complicated than that.

When to See a Doctor

If you've been completely inactive for a long time, have a chronic health condition, are over 45, or experience pain during activity, it's worth having a conversation with your GP before ramping up. This isn't about getting permission — it's about making sure you start in a way that works for your body.

Most GPs will be thrilled to hear you want to move more, and they can point you toward exercise physiology services if you need a structured plan that accounts for any health considerations.

The Only Bad Workout Is the One You Didn't Do

Five minutes of walking is better than zero minutes of anything. A slow lap of the block beats a planned gym session that never happened. Progress doesn't look like what you see on social media — it looks like putting your shoes on and stepping outside, even when you don't feel like it.

You don't need to be fit to start. You just need to start to get fit. And if today all you managed was reading this article — tomorrow, try the walk.
