Why Is It Important To Warm Up Before Exercise?

Regular exercise is one of the best things you can do for your body and mind, but jumping in without warming up first?

That’s a fast track to injury.

No matter your age, experience level, or fitness goals, warm-ups are a crucial part of any physical activity.

Skipping them can lead to unnecessary pain, sore muscles, and even setbacks that keep you from the activities you enjoy most.

As a sports medicine clinic, we see it all the time — a pulled muscle here, a strained joint there — many of them preventable with just a few extra minutes of prep.

In this article, we’ll break down:

• What a warm-up actually is
• Why it matters for your body and performance
• The different types of warm-ups and how to do them effectively
• How to tailor a warm-up routine to your specific workout or sport

Whether you’re just getting back into movement or training at a high level, a good warm-up can set the tone for a safer, more successful workout.

Let’s dive in and get moving — the right way.

What Is A Warm Up?

Simply put, a warm up is an activity you do prior to your workout.

It helps prepare your body and mind for the more demanding activity of your actual workout.

They generally consist of lower impact exercises, similar to the ones you’ll do in your actual workout.

Often times people will skip warm ups.

After all, they add extra time to your workout.

Plus, generally a warm up doesn’t provide the calorie burn and muscle building you will experience when you get to the main event.

But skipping your warm ups can lead to muscle soreness, injury, and excess strain on your heart.

This is especially true if you are participating in high impact and intense exercise.

What Are The Benefits Of Warm Ups?

When you go from not moving to moving, you’ll notice some changes in your body.

Think about something you do every day, such as waking up in the morning.

It can often be difficult to get moving.

To go from being wrapped in a cozy blanket to getting up and starting your day is no easy feat.

And rarely do we jump out of bed and are fully ready to face the day.

We start slowly.

Take time to stretch.

Maybe start the day with a quick game on your phone or browsing Instagram before jumping into more complex tasks.

You’re warming up for your day.

And starting your workout isn’t very different.

You’re making a change to your level of activity, and you need to prepare for it in order to stay safe during your workout session.

Let’s take a closer look.

1. They Prepare Your Body For A Workout

When you start working out, your body goes through certain changes, such as:

• Your heart rate increases
• Your joints loosen
• Your blood vessels widen to increase blood flow to muscles
• Your body temperature increases
• The connection between your body and brain increases
• Your muscles get more oxygen
• Your muscles contract more easily

While these are all good things, if they happen too quickly it can be a shock to your system.

A warm up gives your body a chance to ease into these changes and build up to them gradually.

According to the American Heart Association, warming up before exercise can ultimately keep your heart healthy and strong.

2. They Reduce Your Risk Of Sports Injuries

Everyone wants to see that they’re progressing towards their exercise goals.

This is true whether you’re hitting the gym, going for a run outside, or participating in sports.

The last thing you want is to experience an injury which will set you back and make progress harder.

But this is a lot more likely to happen if you skip your warm up.

According to a 2025 article by Sople and Wilcox, routine warm ups before physical activity can both reduce risk of injury and increase your physical performance.

3. They Improve Flexibility

Stretching is an important component to any warm up.

This practice improves blood flow to your muscles and helps increase your flexibility.

You can aim to stretch after the rest of your warm up when your muscles are warm, but before jumping into the main part of your workout.

4. They Increase Your Body Temperature

Going from being extremely cold to warm very quickly increases your chance of developing muscle cramps and strains.

Jumping into a workout without gradually bringing up your body temperature first is not a great idea.

Doing this can put a lot of excess stress on your muscles, including your heart.

Over a long enough timeline, this can increase your risk of stroke and other heart conditions.

5. They Can Help You Get In A Headspace For Exercise

Mental preparation for things can be just as important, if not more important, than physical preparation.

This seems obvious when it comes to mental exercises.

You don’t take an important test without studying first.

And you’re unlikely to go into an important work presentation without practicing.

But mental preparation for physical activity is just as important.

This is especially true when your exercises get more difficult and your goals get harder to reach.

Warming up will put you in the right headspace to push further and reach your goals.

How To Warm Up Before An Exercise

The way you warm up will depend on the exercise you want to do after you’ve warmed up.

The activities you have planned during your exercise session can inform which muscles to focus on and how to move in your warm up.

Let’s look at some general principles for warming up.

1. General Warm Up

In general, aim to focus your warm up on your major muscle groups.

Activities such as using a stationary bike on a low setting, walking, jogging, or light aerobics are a great way to warm up.

This should last between five and ten minutes and be enough to start to notice a little bit of sweat.

The goal of the general warm up is to increase your respiration and heart rate to get more oxygen to your muscles.

2. Static Stretching

Static stretching simply means holding each stretch for ten to fifteen seconds.

It helps increase overall flexibility and targets all major muscle groups.

Stretching acts to elongate tendons and muscles, allowing for an increase range of motion.

Yoga and pilates both offer great options for this.

3. Warm Up Specific To Your Sport

Once you’ve got a general warm up, and some static stretches out of the way, you’ll want to focus on sport specific moves next.

Since your muscles are already warm by this point, you can increase the intensity a little bit.

Sport specific warm ups are exactly that, sport specific.

For instance, if you’re going to be lifting weights, you might perform the same lifting movements but with lighter weights than you’d use when trying for a personal best.

If you’re going a run or a bike ride, then you’ll cycle or jog at a slower pace than you intend to go at the peak of your workout.

Essentially, consider what your workout or sport entails, and then do those movements at a less intense pace.

4. Dynamic Stretching

Static stretches, as we discussed, involve holding your stretch for ten to fifteen sections.

Dynamic stretching, on the other hand, involves movement.

Using controlled movements, bring the part of your body you want to stretch to the upper limits of what your range of motion allows.

This may start to feel uncomfortable, but be careful of stretching to the point of it feeling painful.

This could increase your risk of injury.

Just like in sports specific warm ups, you can use dynamic stretches in situations that are sport specific.

How Long Should A Warm Up Last?

You may be reading everything involved in the warm up we described above and thinking “wow, that will take as long as my workout”.

And yes, we’ve described all the steps we would all do to warm up in an ideal world.

But that’s not the world we live in, and we don’t all have unlimited time to dedicate to our warm ups and workouts.

So, a good rule you can use is to aim to have your warm up relative to the level at which you’re training or practicing.

For instance, in most hour-long group fitness classes meant for people looking for increase their health and wellness levels, a typical warm up is usually between five and ten minutes long.

However, if you’re involved in your sport or activity of choice at a higher level, then you’ll want to dedicate the appropriate amount of time and effort to warming up to prevent injury.
