Start here
- Aim for 3 sessions/week before increasing intensity.
- Make most sessions easy enough to talk in full sentences.
- Increase time or days before adding intervals.
Movement
Cardio (walking, running, and beyond)
Cardio improves fitness through consistent, mostly easy work. Build an easy base first (walking counts), then add a small amount of harder work if you want to progress.

At a glance
3‑step progression
- Weeks 1–4: 20–40 minutes easy, 3×/week.
- Weeks 5–8: add one longer session or an extra day.
- Then: add 1 interval day (short, controlled) if you want.
Avoid
- Going “all hard” immediately (fatigue and niggles).
- Judging sessions by calories; track time and consistency instead.
- Big jumps in running volume (increase gradually).
A simple progression
Build an aerobic base first; add harder work later.
If you want a straightforward plan, start by making easy sessions normal. Easy sessions build the base that supports everything else: longer walks, quicker running, and better recovery.
- Start with time: choose a duration you can repeat (20–40 minutes).
- Add days or a longer session once the habit feels stable.
- Add intervals only after you can recover from easy volume.
Beginner weekly template
A default week you can repeat.
Week (example)
- Mon: 30 min easy walk (or cycle)
- Wed: 30 min easy + 5 min brisk finish
- Fri: 30–40 min easy cardio
- Optional Sat/Sun: longer easy session (45–75 min)
If you want intervals (later)
- Warm up 10 minutes easy
- 6 × 30 seconds brisk / 90 seconds easy
- Cool down 10 minutes easy
Keep the brisk efforts controlled (not sprinting).
General information only. If you have medical concerns or symptoms with exercise, seek professional advice.
Intensity: a practical check
You don’t need complex zones to start.
Most sessions should be easy. If you can hold a conversation in full sentences, you’re in the right range for base building. If you can only speak a few words, you’re closer to interval intensity.
- Easy: conversational pace (most of the week).
- Brisk: breathing heavier but controlled (short portions).
- Hard: short intervals (once weekly, later).

Useful answers, kept short
Common questions
Open a question for the practical answer. More detailed guidance is linked from the journey above.01What counts as cardio?+
Anything that raises your heart rate and breathing for long enough to train your aerobic system. Brisk walking, cycling, swimming, rowing, jogging, and hiking all count.
02How hard should most sessions feel?+
Easy. A practical check is “can you speak in full sentences?” Most sessions should be conversational. Hard sessions are useful, but they should be a small part of the week.
03Do I need to run to get fitter?+
No. Walking and cycling can build a strong base, especially for beginners. Running adds impact and tends to require a slower ramp. Choose the form you can repeat consistently.
04When should I add intervals?+
After you’ve built a base you can recover from (often 4–8 weeks of mostly easy sessions). Start with short, controlled intervals once per week and keep everything else easy.
05Is a step goal useful?+
Yes for many people. Steps are a simple way to increase total weekly activity. If your goal is fitness, also include a few dedicated sessions of sustained easy effort.
06What if I get pain or unusual symptoms?+
Stop and seek professional advice if you have chest pain, dizziness, fainting, or persistent joint pain. For mild niggles, reduce volume (time) and intensity first and progress more gradually.
