How to warm up before running: a complete routine

Whether you’re just starting out as a runner or preparing for an upcoming race, a good warm-up makes all the difference. In this guide, we’ll demystify why you need to warm up, give you a complete step-by-step dynamic routine, and tailor it to your planned intensity and Québec’s sometimes freezing weather.

Why warm up before running

Warming up isn’t a waste of time or a ritual reserved for elite athletes. It’s a physiological transition that prepares your body to go from rest to exertion. Without it, you’re asking a cold engine to run at full throttle—and that’s exactly where the trouble begins.

Preparing your heart and circulation

At rest, your heart beats slowly, and much of your blood is directed toward your digestive organs rather than your muscles. A progressive warm-up gradually increases your heart rate and redirects blood flow to your legs. The result: when you hit your cruising pace, your cardiovascular system is already up and running, and you avoid that unpleasant feeling of being short of breath during the first few kilometres.

Warming up your muscles and joints

The heat generated by the warm-up makes your muscles more flexible and elastic. Tendons, ligaments, and the fluid that lubricates your joints respond better when they’re warmed up. A warm muscle contracts and relaxes more efficiently, which improves your coordination and stride from the very first minutes.

Improve performance and prevent injuries

The two go hand in hand. A prepared body generates more power and reacts faster, which translates to better performance, especially during intense workouts. At the same time, a warmed-up muscle handles stress better and adapts more easily to changes in pace. This is one of the simplest strategies for preventing injuries such as strains, tendonitis, or the infamous runner’s knee.

Dynamic Warm-Up or static stretching

This is the point that still causes a lot of confusion. For years, we were taught to stretch at length before moving: grabbing our foot behind us, pulling on our thighs, holding the position for thirty seconds. We now know that these static stretches are not the right approach before running.

Static stretching involves holding a position that lengthens the muscle without moving. When done on a cold muscle, they do not improve performance and may even temporarily reduce it by decreasing muscle power and responsiveness. They are useful, but at a different time: for improving flexibility when your muscles are cold, outside of your runs, or very lightly during your cool-down.

Before running, dynamic warm-ups are preferable. The principle is simple: you warm up the body through movement. You perform a series of exercises that gently mimic the motions of running while moving your joints through their full range of motion. It’s active, it raises your body temperature, and it prepares your nervous system to coordinate the effort. In short: movement before exercise, gentle stretching afterward or at another time.

A Complete Step-by-Step Warm-Up routine

Here’s a practical routine you can follow before just about any run. It’s divided into three parts: the cardiovascular warm-up, dynamic movements, and progressive sprints. Allow about ten to fifteen minutes in total.

Step 1: cardiovascular Warm-Up

Always start by gently raising your body temperature. The goal isn’t to tire yourself out, but to warm up.

• Brisk walking (2 to 3 min): For the first few minutes, walk at a brisk pace to get your body going, especially if you’re coming straight from home or your car.
• Very light jogging (5 to 7 min): Follow up with a gentle jog where you could hold a full conversation without any effort. You should feel your breathing settle and a slight warmth rising in your legs.

Step 2: dynamic movements

Once you’re warmed up, stop or find an open area of about 30 metres to do these exercises. Stay flexible and controlled—don’t push yourself too hard.

• Knee lifts (20 to 30 m): Run while alternately lifting your knees toward your chest at a dynamic pace. This activates your hip flexors and quadriceps.
• Heel-to-butt kicks (20 to 30 m): Bring your heels toward your buttocks with each stride. This exercise engages the hamstrings, which are often overlooked during warm-ups.
• Walking Lunges (8 to 10 repetitions per leg): Take a long step forward and lower yourself by bending both knees, then stand back up and repeat with the other leg. This dynamically stretches the hips and improves balance.
• Hip rotations (10 on each side): Stand on one leg and draw large circles with the opposite knee to open up your hip. This is useful for loosening up your pelvis before long runs.
• Side-to-side shuffles (20 to 30 m on each side): Move sideways while keeping your hips low. This movement engages the lateral muscles—which are rarely worked when running in a straight line—and improves your stability.
• Ankle rotations and leg swings (10 per leg): Swing each leg back and forth like a pendulum, then make a few circles with your ankles. Simple, but effective for the joints that absorb all your impact.

Step 3: progressive accelerations

This final step prepares your body to run fast. It’s often called sprints or accelerations.

• Progressive sprints (4 to 6 x 60 to 80 m): Start at a relaxed pace and gradually accelerate to about 80 to 90 percent of your maximum speed over the last few metres, then slow down gently. Walk to recover between each sprint.

These sprints stimulate the nervous system, improve your stride length, and make you feel light and ready to start your workout. After that, you can tackle your main workout.

Adjust the duration based on the planned intensity

Not everyone needs the same warm-up. The more intense your session, the more time and attention you should devote to it.

• Easy run or recovery run: a minimal warm-up is enough. Five to ten minutes of brisk walking followed by a light jog that gradually picks up speed, and you’re all set. The run itself serves as an extended warm-up.
• Speed or interval session: this is where you need to go all out. Do the full routine, including dynamic movements and, most importantly, four to six progressive sprints. A body that’s not properly prepared for sprints is a prime candidate for muscle injury.
• Race day: Tailor your warm-up to the distance. For a 5K or a fast 10K, warm up thoroughly for a full 15 to 20 minutes, since you’ll be off to a fast start right from the gun. For a marathon, keep it very light: a simple warm-up is enough, since you’ll build up your pace during the first few kilometres of the race.

Warming up in cold weather in Québec

Québec winters have their own rules. When the temperature drops below zero, your muscles cool down faster and take longer to reach their ideal temperature. A half-hearted warm-up at minus fifteen degrees is a surefire recipe for a muscle tear.

The first tip: extend your warm-up. What takes ten minutes in the summer can easily take fifteen to twenty in the middle of winter. Your body has to work harder to warm up, and your peripheral circulation is reduced by the cold.

The second tip, which is even more important: do as much of your warm-up as possible indoors. Perform your dynamic movements in a warm place—at home, in the garage, or in the lobby of a gym. Knee lifts, heel-to-butt kicks, lunges, and rotations can all be done in place before you even step outside. That way, you’ll head out with your muscles already warmed up and can start right away with a light jog rather than shivering while walking.

Once outside, keep your warm layers on for the first few minutes and take them off only once you’re well into your run. Also, take the time to start very gradually: in extreme cold, your body and lungs need a few extra minutes to adjust to the freezing air.

Don’t forget the cool-down

The warm-up has a counterpart that’s all too often overlooked: the cool-down. After your workout, don’t stop abruptly. Finish with five to ten minutes of very slow jogging or walking to gradually lower your heart rate and help your muscles flush out the waste products that built up during exercise.

This is also the perfect time for those famous static stretches we mentioned earlier. On warm, supple muscles, a few light, held stretches of the calves, quadriceps, hamstrings, and hips promote flexibility and recovery. Keep it gentle: the cool-down isn’t an intense flexibility session—it’s just a smooth transition back to rest.

Conclusion

Warming up properly is the simplest and most rewarding way to run better and longer. A few minutes of walking, a handful of dynamic movements, and a few bursts of speed are enough to transform your run, while significantly reducing your risk of injury. Adjust the duration based on intensity, extend the warm-up in cold weather, do your warm-up indoors in the winter, and never skip the cool-down. Your body will thank you with every kilometre.
