How to Start Exercising When You’re Out of Shape
You don't need a gym, a trainer or a new wardrobe. You need ten minutes, a realistic plan, and permission to start small.
The best way to start exercising when you’re out of shape is to begin with ten to fifteen minutes of gentle activity most days — usually walking — and add a little more each week. Include two short strength sessions a week using your own bodyweight. Starting small isn’t a compromise. It’s the method that actually sticks.
Check with a doctor first if you have a heart condition, high blood pressure, diabetes, joint problems, are pregnant, or haven’t been active for a long time and have any health concerns. This guide is general information, not medical advice.
How much exercise do you need?
The US Department of Health and Human Services recommends that adults aim for at least 150 minutes of moderate activity a week — such as brisk walking — plus muscle-strengthening activities on two or more days. That sounds like a lot, but it’s just over 20 minutes a day. And any amount is better than none; you’ll feel benefits well before you hit the full target. The Physical Activity Guidelines explain it in more detail.
Why starting small works
Most beginners quit because they start too hard. They go from nothing to five intense workouts a week, feel wrecked, get sore for days and give up. Your heart, lungs, muscles and joints all adapt, but they adapt at different speeds. Tendons and joints take longer than your enthusiasm. A gradual build gives everything time to catch up.
A simple 4-week beginner plan
| Week | Walking | Strength | Notes |
|---|---|---|---|
| 1 | 10 min, 5 days | 1 session | Easy pace; you should be able to chat |
| 2 | 15 min, 5 days | 2 sessions | Add a slightly faster minute or two |
| 3 | 20 min, 5 days | 2 sessions | Try one route with a gentle hill |
| 4 | 25–30 min, 5 days | 2 sessions | Brisk pace for most of the walk |
If a week feels too hard, repeat it. There’s no prize for finishing in four weeks. Consistency over months matters far more.
Beginner strength moves (no equipment)
Do each move for 8 to 12 slow, controlled repetitions. Rest a minute, then repeat the circuit once or twice.
- Sit-to-stand: stand up from a chair and sit back down slowly, without using your hands if you can.
- Wall push-ups: hands on a wall at shoulder height, step back, bend your elbows and push away.
- Glute bridges: lie on your back, knees bent, and lift your hips towards the ceiling.
- Step-ups: step up onto a low, stable step, then down, alternating legs.
- Bird dogs: on hands and knees, extend the opposite arm and leg, hold briefly, switch.
As these get easier, move to push-ups on a table edge, then on your knees. Add a backpack with books for extra resistance on squats and step-ups.
How hard should it feel?
Use the “talk test”. During moderate exercise, you can talk but not sing. If you can’t speak in full sentences, slow down. Some muscle soreness a day or two after strength work is normal when you start. Sharp pain, chest pain, dizziness or unusual shortness of breath are not — stop and get medical advice.
How to stay motivated
- Schedule it. Put your walks in your calendar like appointments.
- Attach it to an existing habit. Walk after breakfast or straight after work.
- Track it simply. A tick on a calendar is enough to build momentum.
- Find a buddy. A friend, a dog or a local walking group makes it harder to skip.
- Focus on how you feel, not just the scales. Better sleep, energy and mood usually arrive first.
What to eat and drink
You don’t need special supplements to start. Eat regular, balanced meals with protein, vegetables, fruit and whole grains, and drink water before and after activity. Our guide on how much water to drink a day covers hydration for exercise.
After the first month
Once 30-minute walks feel easy, you can keep progressing in several ways: walk faster, add hills, try cycling or swimming, or join a beginner class. Keep your two strength sessions — they become even more important as you get older, protecting muscle, bone density and balance.
Common mistakes to avoid
- Doing too much too soon and getting injured.
- Skipping warm-ups; five minutes of easy movement prepares your body.
- Comparing yourself to people who’ve trained for years.
- Treating a missed day as failure. Just do the next one.
- Wearing worn-out shoes for walking; supportive footwear helps prevent aches.
Exercise also improves sleep, which in turn makes exercise easier — a nice loop. See our guide to improving sleep quality for the other half of the equation.
Frequently asked questions
How do I start exercising if I’m very unfit?
Start with 10 minutes of easy walking most days and one or two short bodyweight strength sessions a week, then add a few minutes each week.
How long does it take to get fit?
Most people notice more energy and easier walks within two to four weeks. Bigger changes in fitness usually take two to three months of consistent activity.
Is walking enough exercise?
Brisk walking is excellent aerobic exercise. Add two strength sessions a week to meet general health guidelines.
