No matter where you are in your fitness journey, warming up is one habit you should never skip. As a Sheffield-based personal trainer, Darren Johnston believes a proper warm-up is the foundation of every effective workout, helping improve performance, reduce injury risk and support long-term fitness goals.
Whether you’re strength training, running or taking part in functional fitness, spending just a few minutes preparing your body can make every session safer and more productive.
Why Warming Up Matters Before Exercise
For Darren Johnston, warming up is an essential part of every workout. It prepares both the body and mind by increasing blood flow, loosening muscles and joints, and raising your heart rate gradually.
A good warm-up also helps improve focus, allowing you to approach each session with the right mindset. Building this simple habit leads to greater consistency, helping clients stay fit and make steady progress.
What Happens to Your Body During a Warm-Up?
As your body begins to move, your heart pumps more oxygen-rich blood to your muscles, improving mobility, flexibility and coordination. Your nervous system also becomes more responsive, helping you move more efficiently throughout your workout.
Darren Johnston finds that clients who warm up properly often feel more energised and perform better during strength training, running and functional fitness sessions. A warm-up also provides a valuable opportunity to reduce stress, improve focus and mentally prepare for exercise.
The Benefits of a Proper Warm-Up
A structured warm-up offers a range of benefits, including:
- Improved flexibility and mobility.
- Better balance and coordination.
- Increased strength and movement efficiency.
- Higher energy levels during workouts.
- Improved focus and confidence.
- Greater consistency in training.
- Better long-term physical health and wellbeing.
According to Darren Johnston, long-term fitness is built through consistent habits, and warming up is one of the simplest ways to keep up regular exercise and achieve results.
Dynamic vs Static Stretching, What’s the Difference?
Dynamic stretching involves controlled movements, such as walking lunges, leg swings, arm circles and bodyweight squats, that prepare your body for exercise. This is generally the best option before a workout.
Static stretching, where a stretch is held for an extended period, is more effective after training when muscles are warm. Darren Johnston recommends tailoring your warm-up to the activity, depending on the focus area of the workout.
Common Mistakes People Make When Warming Up
Many people reduce the effectiveness of their workouts by:
- Skipping the warm-up.
- Starting heavy lifts too quickly.
- Performing only static stretches beforehand.
- Failing to warmup the target muscles.
- Not warming up for long enough.
- Ignoring mobility limitations.
- Rushing through movements.
As a personal trainer in Sheffield, Darren Johnston adapts each warm-up to suit the client’s fitness level, experience and goals.
Warming Up for Different Types of Exercise
Different workouts require different warm-ups. Strength training benefits from muscle activation and lighter warm-up sets, while functional fitness focuses on mobility, coordination and movement patterns.
For running, dynamic lower-body movements help prepare the hips, glutes and legs, while even a brisk walk should begin with a few minutes of gentle movement. Tailoring your warm-up helps maximise performance and supports long-term strength and flexibility.
Tips for Making Warm-Ups Part of Your Routine
To make warming up a consistent habit:
- Allow time before every workout.
- Keep your routine simple.
- Match your warm-up to the activity.
- Prioritise movement quality.
- Listen to your body.
- Stay consistent.
Darren Johnston believes the biggest fitness results come from repeating good habits over time, and warming up is one of the easiest to maintain.
