01 · Why warm up?Why a warm-up?
A good warm-up prepares your body for the load: your temperature rises, your blood circulation improves and your nervous system is activated. This makes you run smoother, more efficient and safer, with less risk of injury. Moreover, you will get into the right training feeling (zone, pace, rhythm) faster without your first km feeling heavy or sticky.
Many runners skip a warm-up because they want to “save time”, but in reality these few minutes actually yield benefits: your technique feels freer, your breathing stabilizes faster and your training quality improves.
02 · What happens in your body?What's happening in your body?
When running you demand a lot from your muscles, tendons, nervous system and breathing. A warm-up ensures that all these systems are gradually activated, so that your body is ready before the real strain starts. Instead of jumping abruptly from rest to effort, you build up tension and rhythm in a controlled manner. This makes your technique more stable, your breathing calmer and your body less susceptible to injuries.
Without a warm-up, the first fifteen minutes of your training often costs an unnecessary amount of energy: your breathing lags behind, your legs feel heavy and your stride does not flow well. You can prevent this with a good warm-up and start the training with a body that is already in the correct position.
This is what happens under the hood:
Temperature. ↑ → warmer muscles and tendons move more easily, with less stiffness. Your body literally becomes more flexible, making you feel lighter.
Oxygen delivery ↑ → your body switches more quickly to an efficient aerobic rhythm. Less panting, faster “in your running rhythm”, especially during endurance runs and tempos.
Neuromuscular activation ↑ → sharper ground contact, better stride control, higher cadence. Your nervous system responds faster, making your technique feel smoother early in the run.
Range of Motion. ↑ → hips and ankles move more freely, making your stride feel smoother. Especially important for runners with stiffness in the lower back, hips or calves.
Coordination. ↑ → your body quickly remembers your “technical baseline”. Ideal for fast training, because your stride mechanics become stable and efficient sooner.
So a warm-up is not a formality: it is the link that converts your calm body into an exercise machine that is ready for work.
03 · 3 warm-up phasesThe 3 phases of an effective warm-up
Move quietly
Dynamic mobility
Drills and accelerations
A good warm-up does not feel complicated or heavy: it is a short, logical structure that prepares your body step by step for the training to come. By following these three phases, you activate your heart rate, mobility, technique and rhythm without becoming extra tired. The result? You start smoothly, your breathing stabilizes faster and your body can move more efficiently from the first meters.
Think of it as a kind of “on switch” for your body: first start slowly, then create room to move, and then activate your technical patterns. This makes a huge difference, especially during intensive training (intervals, hills, tempo) — but even with easy runs it ensures that you get into a comfortable flow faster.
| Phase | Duration | Target | Examples |
|---|---|---|---|
| 1. Get moving | 3–5 min | Heart rate gradually increases, finding rhythm | Walking → dribble, small steps, gentle arm swing |
| 2. Dynamic mobility | 3–5 min | Preparing joints and tendons | Leg swings, Hip openers, Walking lunges, Ankle rolls |
| 3. Running drills & accelerations | 2–4 mins | Technique, activation and rhythm | A-skips, Butt kicks, High knees |
This structure ensures that your cardiovascular system, nervous system and technique move in the same direction. This way, the first km does not feel heavy or awkward, but as if your body knows exactly what the intention is.
Why this sequence works
A warm-up is most effective when your body is prepared step by step for higher intensity. By first moving slowly, then adding mobility and then doing drills and accelerations, you build up your load in a controlled manner. This way you activate exactly the systems you need — heart rate, technique, rhythm and muscle tension — without unnecessary fatigue.
A warm-up is not the prelude to training. It is the first part of the training.
04 · Extra warm-up tipsExtra tips for a good warm-up
A warm-up does not have to be complicated, but a few smart choices do make it much more effective. By taking into account the type of training, the weather and how you feel, you will get more out of it without losing extra time.
With this approach you will feel technically smoother, more efficient and better prepared from the first meters — the best basis for any training. A good warm-up is not a waste of time, but an investment in better performance and staying injury-free.
05 · Warm-up before racingWarming up before competition
A warm-up before a race prepares your body and mind for what is to come. You increase your heart rate, activate your muscles and ensure that you start smoothly.
For a short distance such as the 5 km, a good warm-up is extra important, because you are running relatively fast from the start. So you really want to “turn on” your body. A typical 5K warm-up consists of 10–15 minutes of easy running, followed by dynamic exercises (such as knee lifts, heel lifts and skips) and 4 short strides of 80–100 meters at race pace.
For longer distances such as 10 km or a half marathon, the warm-up needs to be less intense. You start the race more calmly and you can use the first km to get into your rhythm.
In short: the shorter the distance, the more important a thorough warm-up.
06 · Choose your routineChoose a routine based on your training
A warm-up does not always have to be the same. By adjusting it to the intensity of your training, you prepare exactly the systems you need: mobility for smooth steps, neuromuscular activation for tempo, and light cardio to pleasantly raise your heart rate. The five routines below will give you just the right amount of preparation — without making your warm-up take longer than necessary.
1. Recovery run (zone 1–2) – 8 minutes
Calm, relaxed, focused on blood circulation. You don't have to do anything technically complicated: the goal is simply to get moving comfortably.
2. Endurance run (zone 2) – 10 minutes
Your “basic” warm-up: enough to become flexible, but not heavy. Perfect for long or easy runs.
3. Tempo run (zone 3–4) – 12 minutes
For sessions where you want to walk briskly but in a controlled manner. The warm-up focuses on rhythm, technique and breathing.
4. Interval/Track – 12–15 minutes
This warm-up activates your nervous system, technique and explosiveness. Ideal for intensive blocks.
5. Cold or wet day (indoor activation) – 8–10 minutes
Perfect when it's too cold outside to warm up quietly.
07 · Warm-up mistakesCommon mistakes during warm-ups
Even with good intentions, a warm-up often goes wrong. Small mistakes can cause you to start your training stiff, restless or half tired. By recognizing these pitfalls, you will get much more out of the first km and reduce your risk of injury.
08 · Checklist (1 minute)Checklist (1 minute)
A good warm-up doesn't have to be complicated. With this short checklist you can check just before you start whether your body is ready for the first meters and whether your technique is “on”. Think of it as your final mental and physical reset.
