What is Dynamic Warm-up?
Why before running, you should not start by stretching only.

Before running, many people have the misconception that "you must stretch beforehand," particularly when bending over to touch your toes, pull your calves, pull your thighs, or hold your legs in place for several seconds. However, the truth is that starting a run by holding your legs in place alone may not be the most effective way to prepare your body, especially if you are going to run fast, cover long distances, or prepare for a race.

What Runners Should Know More About Dynamic Warm-up Or an active warm-up is a body preparation technique involving continuous movements such as jogging, quick strides, knee raises, leg swings, lunge steps, or movement patterns similar to actual running.

This article will explain what Dynamic Warm-up is, how it differs from static stretching, why you should "move your body awake" before running, and which warm-up methods Thai runners can actually apply before training or on the field.

This article is based on: Research review on the effects of static and dynamic stretching on performance, ACSM guidelines on stretching techniques, and recommendations from the Hospital for Special Surgery regarding pre-run dynamic warm-ups.

What is Dynamic Warm-up?

Dynamic Warm-up It is an active warm-up that moves joints and muscles through various movements continuously to gradually raise body temperature, stimulate blood circulation, and prepare muscles for the main activity.

For runners, Dynamic Warm-up is more than just a "stretch"; it simulates the movements involved in running, such as knee extension, leg swing, stride, hip movement, ankle motion, and gradually increasing heart rate before the actual run begins.

Simple to remember: Dynamic Warm-up is a way to "wake up your body to run" by moving rather than holding muscles still even before movement begins.

A review of research by Behm and Chaouachi suggests that a proper warm-up should begin with light aerobic activity, followed by dynamic stretching, and conclude with sport-specific exercises that closely mimic the actual running rhythm.

What is the difference between Static Stretching and Dynamic Warm-up?

Many people confuse "stretching" with "warm-up," as these terms are often used interchangeably, but they serve distinct roles—especially when applied before running.

Topic Static Stretching Dynamic Warm-up
Characteristics Hold the position as is, such as pulling the ankle back 20–30 seconds. Continuously move, such as leg swings, high knees, and walking lunges.
Primary Goal Increase flexibility or relax muscles Prepare your body to move and exert effort.
Suitable for which season? Post-workout or separate from daily mobility/flexibility training Before running, before training, before race
Feelings Ning Chong Relax Wake up, warm up, move forward.

It does not mean that static stretching is "bad," but it must be done at the right time. ACSM recommends that static stretching improves flexibility by being performed after an active warm-up and can be done regularly 2–3 times per week or more, depending on individual goals.

However, if the goal is to prepare for a run in just a few minutes, the Dynamic Warm-up is often better suited, as it gradually transforms the body from a static state into an active one.

Why should you not start your run by stretching and holding your feet?

Stretching while your body is still cool or has not yet moved much may not help you be ready to run as many people think it does because running requires blood circulation, muscle temperature, neural-muscle coordination, and simultaneous ankle, knee, hip, and body movement.

A research review indicates that dynamic stretching typically poses no harm to performance and may enhance certain aspects of movement or athletic capability, while static stretching is ideal for developing flexibility during rest periods or after the body has warmed up.

  • 1. Running requires continuous movement, not just flexibility.
    Running is the collaboration of the ankle, calf, hip, midsection, and arm. Dynamic Warm-up prepares the movement system more effectively.
  • 2. The body must gradually increase its temperature and heart rate rhythm.
    Running or light jogging before standing still helps blood circulation and muscle activation more effectively than immediately standing still.
  • 3. Dynamic Warm-up prepares your posture to closely resemble real running.
    High knees, leg swings, or walking lunges encourage greater movement of hips, knees, and ankles in a running-oriented manner.
  • 4. Static Stretching is beneficial but should be performed at the right time.
    If you wish to extend your stride to enhance flexibility or relax muscles, you may do so during the run or on days focused on mobility rather than immediately before starting the run.

In summary, before running, you do not need to discard all static stretching; instead, reorganize your routine by first moving your body to warm up, followed by appropriate stretching or mobility work as needed.

Warm-up routine: 8–10 minutes before running for runners

For beginners or those preparing for races, don't overcomplicate your training. Start with short, practical routines of 8–10 minutes before practice or on your regular run day.

Simple Warm-Up Before Running

  1. Run fast or jog for 2 minutes To gradually increase your heart rate.
  2. Ankle Circles 30 seconds per side Rotate your ankle to receive the impact of the ground.
  3. Leg Swings 10–12 times per side Control your front, back, and left-right leg movements.
  4. Walking Lunge 8–10 Steps per Side Prepare hips, knees, and balance.
  5. High Knees 20–30 seconds Stimulate leg rhythm and knee lift
  6. Butt Kicks 20–30 Seconds Rejuvenate the gluteal muscles, enhance stride rhythm, and ignite your leg movement.
  7. Easy Strides 2–3 rounds Slowly accelerate for short distance to prepare for real peiz running.

If it is a light run day, just 5–8 minutes may be sufficient; however, if it is a fast-paced training day, tempo interval sessions or race events should include more warm-up time, gradually increasing speed without jumping from standing still to running immediately.

The key is to execute every movement with control—never force, never rush, and never overexert yourself before starting your run. The purpose of warming up is "preparing the body," not "burning all your energy beforehand."

Common mistakes when warming up before running

Many people don't get hurt because they "don't know how to warm up," but instead because they overheat, overwork themselves, or choose a stance that doesn't match what they're actually doing.

  • 1. Stretching for an extended period while the body remains cool.
    If you have not yet walked or moved, begin with light movement first, then gradually transition into stretching or mobility exercises.
  • 2. Overheat during warm-up
    Dynamic does not mean fast or heavy jumps; beginners should begin with controlled movements first.
  • 3. Forget to warm up your ankles and hips
    Runners often focus on the legs, but the ankle and hip are key points that help improve foot placement and enable smoother strides.
  • 4. No warm-up adjustment based on training type
    A light run warm-up may be shorter, but a fast warm-up or race day should prepare your body more thoroughly, especially around the legs, hips, and core.

A good warm-up is not difficult but must align with the upcoming run. The more intense your training becomes, the more time your body needs to adapt.

VING Perspective: Prepare your body before running and prepare your feet after running.

When running is a daily routine, warming up is the phase that prepares your body before action, while aftergym care is the phase that ensures you are ready for the next day. Both are equally essential.

After running, your feet and calves undergo repeated impact, especially during high-intensity training sessions, long-distance runs, or race day preparations. Removing your running shoes, changing socks, and wearing breathable, comfortable shoes is another small step that helps your feet feel more relaxed.

VING Perspective

For VING, a good run doesn't begin at the first kilometer; it starts with warming up and ends with foot care after running. Running sandals or Recovery Sandals are part of the running routine for runners who help their feet feel light, comfortable, and ready to continue.

Simply put, before running, your body needs to "move to prepare," and after running, your feet need to "rest to recover." If you make these two phases a habit, your running training will feel more organized, and your body will respond better to long-term training.

Summary: Before running, move first, then stretch, and finally run with confidence.

Dynamic Warm-up is an active warm-up that prepares the body for running more effectively than static stretching alone, as running demands coordination of rhythm, heart rate, muscles, joints, and the nervous system working together.

Static stretching offers benefits, particularly regarding flexibility and muscle relaxation, but should be performed at the right time—such as during running or as part of mobility training—not immediately followed by high-speed running.

If you want to prepare better before your run, start with an easy 8–10 minute warm-up: fast walking, light jogging, ankle and hip movements, and light drills. This will help your body feel ready for every kilometer.

Before running, prepare your body; after running, prepare your feet to rest.

Complete your running routine with VING's premium footwear and running gear, including running sandals, running socks, and equipment designed to keep you comfortable from the moment you set off until the finish line.

FAQ: Frequently Asked Questions About Dynamic Warm-up Before Running

How long does it take to warm up before running?

Generally, 8–10 minutes is sufficient for a standard run; however, during training sessions, long-distance runs, or races, additional warm-up time may be required, gradually increasing intensity before departure.

Can it stretch before running?

Stretching is possible but should not be initiated for extended periods while the body is still cool. Walk or warm up by movement first, then gradually stretch specific areas as needed.

Is the Dynamic Warm-up suitable for beginners?

Perfect because it helps new runners gradually transition from a rest mode to a running mode without needing to start fast or hard from the very first moment.

If you have limited time, which pose should you warm up first?

Start with fast walking or light jogging, followed by leg swings, ankle circles, high knees, and easy strides. These gentle movements will help prepare your feet, hips, and running rhythm.

Should you perform another Dynamic Warm-up after running?

After running, focus on a cool-down by taking slow, light steps, followed by static stretching or light mobility exercises to relax the muscles rather than performing a dynamic warm-up before running.
