In short:
- Cardio training and running are among the most effective tools for improving cardiovascular health and extending lifespan.
- The ACSM recommends that adults get at least 150 minutes of moderate aerobic activity per week.
- Even 5–10 minutes of running a day reduces the risk of all-cause mortality by up to 27%.
- The keys to success are gradual progression, adequate recovery and consistency.
Cardio training and running are cornerstones of modern fitness — accessible, well researched and suitable for almost every age group. This guide explains how to get started, when to raise the intensity and what to avoid so that your training is both safe and effective.
What are cardio training and running, and what health benefits do they offer?
Cardio training and running are forms of endurance training that challenge the cardiovascular system and increase the body’s capacity to use oxygen (VO₂max). Regular aerobic exercise improves heart function, lowers blood pressure, stabilizes blood sugar and helps regulate body weight.
According to the World Health Organization (WHO) physical activity guidelines, adults should do at least 150–300 minutes of moderate-intensity activity per week. The ACSM position stand describes regular aerobic training as one of the most effective tools for preventing cardiovascular disease (Garber et al., 2011). Running, the most common form of cardio training, reduces the risk of all-cause mortality by up to 27% and the risk of cardiovascular mortality by up to 45% compared with not running (Lee et al., 2014). You’ll find a further overview of aerobic training in the article Cardio training.
How do you start running — an approach suited to beginners?
The most important thing for a beginner is to start slowly and increase the training load gradually. A practical starting point is alternating walking and running: 1 minute of running, 2 minutes of walking, repeated over 20–30 minutes. Studies show that even 5–10 minutes of running a day at a low pace brings significant health benefits (Lee et al., 2014).
Heart rate zones are the main tool for managing intensity. Maximum heart rate is calculated with the more accurate formula 208 − 0.7 × age (Tanaka et al., 2001), which gives a better result than the older 220 − age formula. The moderate-intensity zone is 50–70% of maximum heart rate, and the high-intensity zone is 70–85%.
For well-rounded progress, it’s worth putting together a structured training program that takes into account training volume, recovery days and your specific goals.
What forms of cardio training are there, and how do you choose between them?
Cardio training isn’t limited to running. The main forms are:
- Steady low-intensity training (LISS) — long-duration, moderate-intensity activity (walking, jogging, swimming, cycling). Well suited to building an endurance base and to recovery.
- Interval training (HIIT) — alternating short, intense efforts with active rest periods. The ACSM recommends including HIIT no more than 2 times a week (Garber et al., 2011).
- Tempo running — running close to the anaerobic threshold (about 80–85% of max heart rate), which develops lactate tolerance.
- Long slow runs — building endurance at a low heart rate (60–70% of max heart rate).
It’s worth knowing that cardio training is good for your legs too — regular running strengthens the muscles, ligaments and tendons of the lower limbs, reducing the long-term risk of knee and ankle injuries.
What are the most common mistakes in cardio training and running?
1. Progressing too fast. A sudden increase in running volume is the main cause of injuries. The so-called 10% rule helps prevent orthopedic overload: weekly running volume shouldn’t increase by more than 10% per week (Warburton et al., 2006).
2. Skipping the warm-up. A dynamic warm-up (5–10 minutes) before running reduces muscle tension and improves running economy.
3. Neglecting nutrition. Adequate carbohydrate and protein intake is important for longer training sessions and for recovery. Endurance athletes need 1.2–1.4 g of protein per kilogram of body weight per day (Garber et al., 2011). You’ll find more science-based recommendations in the article dietary supplements for athletes.
4. Underestimating recovery. Lack of sleep and constant overload lead to overtraining. The ACSM recommends taking at least 1–2 recovery days per week.
How much cardio training is enough for your health?
The WHO physical activity guidelines for adults call for:
– 150–300 minutes per week of moderate aerobic activity, OR
– 75–150 minutes of vigorous aerobic activity, OR
– an equivalent combination of the two.
Additional health benefits are possible up to 300 minutes of moderate activity per week (Wen et al., 2011). Studies show that even 15 minutes of moderate activity a day adds three years to life expectancy on average (Wen et al., 2011). The key to success is consistency: a sensible increase in volume and intensity, adequate recovery and regularity deliver better long-term results than occasional bursts of intense training.

Frequently asked questions
How often should you run to get the health benefits?
According to WHO recommendations, 150 minutes of moderate aerobic activity per week is enough. In practice, that means 3–5 running workouts a week of 30–50 minutes each. Even running 2–3 times a week brings noticeable health benefits.
Does cardio help you lose weight?
Yes, but only in combination with your diet. Running burns on average 400–600 kcal per hour, depending on your speed and body weight. The most effective approach is to combine aerobic training with a moderate calorie deficit and adequate protein intake to preserve muscle mass.
What is the difference between HIIT and regular running?
HIIT (high-intensity interval training) consists of short, maximum-effort bouts (20–60 seconds) and active rest periods. It improves VO₂max quickly and saves time, but it puts more strain on the body. Regular steady running (LISS) is the better choice for building an endurance base and for recovery.
How can you avoid running injuries?
The main preventive measures are: increasing your volume by no more than 10% per week, doing a dynamic warm-up before running, wearing suitable shoes, adding strength training to your program (especially leg muscle and core exercises), and getting enough sleep and recovery.
Is cardio suitable for older adults too?
Yes, cardio is suitable for all age groups and is especially beneficial for people over 50. In older age, you should start at lower intensities, take the condition of your joints into account and favor low-impact forms such as walking, swimming or cycling. Consult a doctor if you have heart disease or other chronic conditions.
