A warm-up is one of the simplest ways to prepare your body for exercise, yet it’s also one of the parts of a workout that beginners are most likely to skip. If you’re excited to start training, spending a few minutes warming up can feel unnecessary. However, preparing your body before exercise can help movements feel more comfortable and allow you to perform at your best.
A good warm-up doesn’t need to be long or complicated. The aim isn’t to tire yourself out before your workout begins. Instead, it’s about gradually preparing your muscles, joints, heart and mind for the activity you’re about to do.
If you’re looking for a complete guide to reducing your risk of injury while exercising, our article How to Prevent Workout Injuries (Beginner Tips) explains the habits that help you train safely from the very beginning.
What is a warm-up?
A warm-up is a short period of light activity performed before your main workout. It gradually increases your heart rate, improves blood flow to your muscles and prepares your body for more demanding exercise.
Think of it as giving your body time to switch from everyday activities to physical exercise. Rather than asking your muscles and joints to suddenly work hard, a warm-up allows them to adjust progressively.
Although warming up is often associated with preventing injuries, its benefits go beyond safety. Many people find they move more comfortably, feel less stiff and perform exercises with better control after warming up properly.
Why warming up matters
Your body doesn’t instantly become ready for vigorous exercise the moment you start moving. If you’ve been sitting in a classroom, working at a desk or relaxing at home, your muscles and joints have been working at a relatively low level.
A warm-up gradually bridges the gap between rest and exercise. As your body temperature rises slightly and your circulation increases, movements often begin to feel smoother and less restricted.
Warming up also gives you an opportunity to concentrate on your technique before your workout becomes more challenging. This can be particularly helpful if you’re learning new exercises or returning after a break.
If you’ve ever wondered whether warming up is actually necessary, our article Do You Need to Warm Up Before Working Out? looks at the evidence in more detail.
Start with light movement
Most warm-ups should begin with gentle movement that gradually raises your heart rate without leaving you out of breath.
Examples include:
- brisk walking
- easy cycling
- light jogging
- marching on the spot
- using a rowing machine at a comfortable pace.
This first stage doesn’t need to be difficult. The goal is simply to help your body transition into exercise rather than shocking it with sudden high-intensity effort.
Prepare your joints by moving them
Once you’ve started to increase your heart rate, it’s helpful to move the joints that you’ll be using during your workout.
These movements are often called dynamic mobility exercises because they involve moving your body through comfortable ranges of motion rather than holding long stretches.
For example, before a lower-body workout you might perform leg swings, hip circles, bodyweight squats or walking lunges. Before an upper-body session, shoulder circles, arm swings and controlled reaching movements can help prepare the shoulders and upper back.
The aim isn’t to force your joints into uncomfortable positions. Instead, you’re simply encouraging them to move naturally before asking them to work harder.
Practise the movements you’ll be performing
One of the most effective parts of any warm-up is rehearsing the exercises you’re about to perform.
If you’re planning to squat with weights, begin by performing a few bodyweight squats. If you’re about to lift dumbbells, practise the movement using very light weights first. Before going for a run, spend a few minutes walking before gradually increasing your pace.
This gives your muscles and nervous system an opportunity to practise the movement while allowing you to check that everything feels comfortable before increasing the intensity.
Beginners often find that exercises feel much more controlled after completing a few lighter practice repetitions.
Match your warm-up to your workout
Not every warm-up should look exactly the same. The best warm-up is usually one that prepares you for the specific activity you’re about to perform.
For example, someone preparing for a strength-training session will benefit from different movements than someone about to play football or go for a long run.
If you’re lifting weights, focus on preparing the muscles and joints you’ll be using during that session. If you’re running, place greater emphasis on your hips, knees, ankles and gradually increasing your running pace. If you’re playing a sport involving quick changes of direction, include movements that prepare your balance and coordination.
Thinking about your warm-up as the first part of your workout rather than a separate task often makes it feel more purposeful.
Should you stretch during your warm-up?
Many people think stretching and warming up are exactly the same thing, but they actually serve different purposes.
Most modern warm-ups focus on keeping your body moving rather than holding long stretches before exercise. Gentle, controlled movements that take your joints through their natural range of motion are often more appropriate immediately before most workouts because they prepare your body for movement rather than encouraging it to relax.
Long, static stretches are often better suited to improving flexibility at other times, such as after exercise or during dedicated mobility sessions, depending on your goals.
If you’re unsure which approach is best, our articles Should You Stretch Before or After Exercise? and Does Stretching Prevent Injuries? explain the differences in more detail.
How hard should your warm-up feel?
A warm-up should leave you feeling ready to exercise, not exhausted before your workout has even started.
You should notice your breathing becoming slightly faster and your body feeling warmer, but you should still be able to hold a conversation without difficulty. If you’re already struggling to catch your breath, you’ve probably increased the intensity too quickly.
By the time your warm-up finishes, your movements should feel smoother, your muscles less stiff and your body ready to move into the main part of your workout.
Common warm-up mistakes
Many beginners don’t avoid warming up completely—they simply don’t warm up in a way that prepares them for the activity they’re about to do.
Some of the most common mistakes include:
- starting the workout at full intensity immediately
- performing stretches without any light movement first
- copying complicated warm-up routines from experienced athletes
- warming up muscles that won’t be used during the workout
- turning the warm-up into another full workout.
Your warm-up doesn’t need to be perfect. It simply needs to prepare you for the exercise you’re about to perform.
Do you always need the same warm-up?
Not necessarily. The amount of preparation you need often depends on the activity, the environment and how your body feels that day.
For example, if you’re going for a gentle walk, you may only need a minute or two to settle into a comfortable pace. On the other hand, a heavy strength-training session, a football match or a fast run will usually benefit from a more structured warm-up.
You may also find you need a little longer to warm up first thing in the morning or during colder weather, when your muscles and joints can feel stiffer than usual.
Listen to your body before every workout
A warm-up is also a useful opportunity to check how your body feels before you begin exercising properly.
If you notice unusual pain, dizziness, significant fatigue or movements that don’t feel normal, it may be sensible to adjust your workout rather than ignoring these warning signs. Sometimes reducing the intensity, choosing different exercises or taking an extra recovery day is the better long-term decision.
Learning to recognise how your body responds before each workout is an important part of exercising safely.

A good warm-up sets the tone for your workout
A warm-up isn’t something you have to do before exercise—it’s something that helps you get more from the workout you’re about to begin. Spending a few minutes preparing your body can make movements feel more comfortable, help you focus on your technique and allow you to transition gradually from everyday life into physical activity.
Remember that the best warm-up is one that matches the workout you’re about to do. It doesn’t need to be long, complicated or exhausting. By keeping it simple and consistent, you’ll develop a routine that supports both your performance and your long-term enjoyment of exercise.
