Whether you’re hitting the gym, heading out for a run, or gearing up for game day, warming up properly is one of the most important things you can do to prevent sports injuries and enhance performance. Skipping your warm-up can lead to muscle strains, joint pain, or even long-term damage that could sideline you for weeks—or worse.
As a physiotherapist with years of experience working with athletes of all levels, I’ve seen how powerful a good warm-up can be. A proper warm-up doesn’t just prepare your body for exercise—it also improves mobility, activates the right muscles, and primes your nervous system for optimal performance.

Why Warming Up Matters
Before jumping into the exercises, it’s essential to understand why warming up is crucial:
- Increases blood flow to muscles and joints
- Improves flexibility and range of motion
- Activates neuromuscular pathways
- Prepares your mind for the upcoming activity
- Reduces the risk of strains, sprains, and muscle tears
A proper warm-up should last about 10–15 minutes, combining dynamic stretching, muscle activation, and sport-specific movements. Now, let’s explore the five essential exercises.
1. Jumping Jacks – Full-Body Dynamic Activation
Target Areas: Shoulders, calves, quads, glutes, core
Duration: 30–60 seconds
Reps: 2–3 sets
Why it works:
Jumping jacks are a classic dynamic warm-up exercise that increases heart rate, improves circulation, and warms up key muscle groups. It’s an excellent way to get your whole body moving quickly.
How to perform:
- Stand upright with feet together, arms at your sides.
- Jump your feet out while raising your arms overhead.
- Quickly return to the starting position.
- Repeat at a moderate pace.
Tip: Focus on rhythm and full range of motion for optimal activation.
Injury Prevention Benefits:
By warming up your entire body, jumping jacks reduce joint stiffness and prepare muscles for more intense activity. They’re especially helpful for cardio-based or full-body sports like basketball, soccer, or tennis.
2. Leg Swings – Improve Hip Mobility and Flexibility
Target Areas: Hamstrings, hip flexors, glutes, lower back
Reps: 10–15 swings per leg (front-to-back and side-to-side)
Why it works:
Tight hips are a major cause of lower-body injuries. Leg swings help loosen up the hip joints, improve range of motion, and prepare the legs for sprinting, jumping, or squatting.
How to perform (Front-to-Back):
- Stand near a wall or pole for balance.
- Swing one leg forward and backward in a controlled motion.
- Keep your core tight and your upper body stable.
- Switch legs after 10–15 reps.
Side-to-Side Swings:
Swing one leg across your body and then out to the side. Repeat for 10–15 reps before switching.
Injury Prevention Benefits:
Improves dynamic flexibility in the hips and legs, helping prevent groin pulls, hamstring strains, and hip impingement.
3. Arm Circles – Shoulder and Upper Body Warm-Up
Target Areas: Shoulders, rotator cuff, upper back
Reps: 10 forward, 10 backward (small to large circles)
Why it works:
Your shoulders are one of the most injury-prone joints, especially in overhead or throwing sports like swimming, tennis, baseball, or CrossFit. Arm circles help increase synovial fluid in the shoulder joint and warm up the rotator cuff muscles.
How to perform:
- Stand with arms extended straight out to your sides.
- Make small forward circles, gradually increasing the size.
- After 10–15 seconds, reverse direction and repeat.
- Keep your shoulders relaxed and avoid shrugging.
Injury Prevention Benefits:
Arm circles improve shoulder mobility and joint lubrication, reducing the risk of rotator cuff tears, impingement, and shoulder stiffness.
4. Walking Lunges with a Twist – Dynamic Stretch + Core Activation
Target Areas: Quads, glutes, hamstrings, hip flexors, obliques
Reps: 10–12 per side
Why it works:
Walking lunges combine leg activation, hip mobility, and core engagement—making them a powerhouse warm-up move. Adding a twist incorporates spinal rotation, which is essential for athletes in sports like golf, baseball, and martial arts.
How to perform:
- Take a step forward into a lunge position.
- Twist your torso toward the front leg.
- Return to standing and repeat on the opposite leg.
- Keep your knee aligned over your ankle.
Injury Prevention Benefits:
This move targets multiple planes of movement, making it perfect for prepping the body for real-world athletic demands. It strengthens stabilizers and helps prevent ACL injuries, lower back pain, and hip strains.
5. High Knees – Cardiovascular Warm-Up and Coordination
Target Areas: Core, hip flexors, calves, quads
Duration: 20–30 seconds
Reps: 2–3 rounds
Why it works:
High knees elevate your heart rate, activate your core, and improve neuromuscular coordination. It’s a favorite among sprinters and team sports athletes because it gets your body moving explosively and prepares your central nervous system for action.
How to perform:
- Stand tall and lift your knees as high as possible toward your chest.
- Pump your arms in coordination.
- Maintain a quick pace, landing lightly on the balls of your feet.
Injury Prevention Benefits:
High knees build hip stability, improve coordination, and reduce the likelihood of muscle tears, particularly in the hamstrings and lower back.
Warm-Up Tips from a Physiotherapist
To maximize the benefits of your warm-up and avoid sports injuries:
- Start slow, then build intensity
- Focus on dynamic—not static—stretching
- Incorporate sport-specific movements
- Hydrate before and after your warm-up
- Use warm-up time to mentally focus on your performance goals
Avoid doing static stretches before your workout or game. Save those for your cool-down when your muscles are already warm.
Customizing Your Warm-Up Based on Your Sport
Each sport places unique demands on your body. Here’s how to modify your warm-up:
- Running: Emphasize leg swings, high knees, and calf raises
- Weightlifting: Add banded glute bridges and shoulder mobility drills
- Team sports (soccer, basketball): Include lateral shuffles and jump squats
- Swimming or tennis: Focus on arm circles, thoracic twists, and rotator cuff activation
- Cycling: Warm up with hip openers, knee circles, and gentle pedaling
What Happens If You Skip the Warm-Up?
Skipping your warm-up might save time in the short term, but the long-term consequences can be serious:
- Decreased performance
- Higher risk of injury
- Tight muscles and poor range of motion
- Longer recovery time post-workout
Think of warming up as “insurance” for your body. You wouldn’t drive without a seatbelt—so why exercise without preparation?
Frequently Asked Question
How long should a warm-up session last before exercise or sports?
A: A proper warm-up should last between 10 to 15 minutes, depending on the intensity of the workout or sport you’re preparing for. This allows enough time to raise your heart rate, activate key muscle groups, and improve mobility.
What is the difference between dynamic and static stretching in a warm-up?
A: Dynamic stretching involves controlled, movement-based stretches that increase circulation and range of motion—ideal for warming up. Static stretching, where you hold a stretch for 20–30 seconds, is best saved for the cool-down after exercise to aid flexibility and recovery.
Can I skip warm-up exercises if I’m short on time?
A: It’s not recommended. Even a 5-minute warm-up with 2–3 key movements can significantly reduce your risk of injury and improve performance. Skipping it increases your chance of strains, pulls, and poor workout results.
Are these warm-up exercises suitable for beginners?
A: Yes! The 5 warm-up exercises—jumping jacks, leg swings, arm circles, walking lunges with a twist, and high knees—can be modified in intensity and are beginner-friendly. Focus on good form and controlled movement.
Should I warm up differently based on the sport I’m doing?
A: Absolutely. While these five exercises form a solid general warm-up, you should add sport-specific drills (e.g., lateral movements for basketball or shoulder mobility work for swimming) to prepare your body for specific demands.
What injuries can be prevented with proper warm-ups?
A: A consistent warm-up routine helps prevent muscle strains, ligament sprains, joint stiffness, tendonitis, lower back pain, and even ACL injuries. It improves neuromuscular coordination and joint lubrication.
Can I do these warm-up exercises every day?
A: Yes! These dynamic movements are safe to perform daily, especially if you’re training regularly. They not only prepare your body for workouts but also improve mobility, posture, and movement quality over time.
