A dynamic warm-up before running is one of the simplest interventions with the most consistent evidence for reducing injury risk and improving early-run performance. Yet it is also one of the most consistently skipped. Most recreational runners go from sitting to running in under two minutes, asking cold muscles, stiff joints, and an unprimed neuromuscular system to immediately produce the forces and coordination of running.
This guide covers the specific exercises that most effectively prepare the body for running, why each one works, and how to structure them into a complete pre-run routine that takes 5 to 8 minutes and significantly reduces the injury risk and discomfort of the first kilometres.
Why Dynamic Rather Than Static Warm-Up
The research on pre-exercise stretching consistently shows that prolonged static stretching (holding stretches for 30 to 60 seconds) before exercise can temporarily reduce muscle force production and the elastic stiffness of tendons. Both of these effects are counterproductive before running, which requires high force production and relies on the energy-returning spring properties of tendons.
Dynamic warm-up exercises, which involve controlled movement through the range of motion without long holds, produce the opposite effects:
- Increase muscle temperature (warm muscles contract faster and more efficiently)
- Increase joint synovial fluid production (reducing the friction in joints during the first kilometres of running)
- Activate the neuromuscular system (improving the speed and accuracy of muscle firing patterns)
- Promote blood flow to the working muscles
- Prime the specific movement patterns used during running
- Activate the glutes and hip stabilisers that frequently underperform early in a run
The Complete Pre-Run Dynamic Warm-Up
The following routine is organised in a specific sequence: starting with the most low-intensity exercises and progressively building toward running-specific movements. This progressive sequence prepares the neuromuscular system gradually rather than jumping immediately to high-demand movements.
Approximate total time: 6 to 8 minutes
Exercise 1: Leg Swings (Sagittal Plane)
Purpose: Mobilises the hip flexors and extensors through the running-specific forward-backward range of motion. Increases hip joint synovial fluid and prepares the hip for the flexion-extension cycle of running.
How to do it:
- Stand beside a wall or post, holding lightly for balance
- Swing the outer leg forward and backward in a controlled arc
- Begin with a small amplitude and progressively increase the swing range over each repetition
- The leg swings freely like a pendulum, not forced to an extreme range
- Complete 15 to 20 swings per leg
Running relevance: Every running stride involves hip flexion (knee drive forward) and hip extension (leg push behind). Leg swings specifically prepare this sagittal plane hip movement pattern and activate the hip flexors that drive the knee forward during the swing phase.
Exercise 2: Leg Swings (Frontal Plane)
Purpose: Mobilises the hip abductors and adductors in the lateral range. Activates the gluteus medius that stabilises the pelvis during the single-leg stance phase of running.
How to do it:
- Face the wall with both hands on the wall
- Swing one leg across the body (inward) and then out to the side (outward)
- Begin with small amplitude and increase progressively
- Keep the trunk stable throughout: only the leg moves
- Complete 15 swings per leg
Running relevance: As covered in the lateral band walk exercise and glute activation with bands articles on this site, gluteus medius activation is a primary determinant of running economy and injury prevention. The lateral leg swing specifically activates the gluteus medius before the run.
Exercise 3: Hip Circles
Purpose: Takes the hip through its full range of rotation, mobilising the hip capsule in all directions and activating the hip external and internal rotators.
How to do it:
- Stand on one leg with a slight knee bend
- Lift the free knee to hip height
- Rotate the hip in a large circle: forward, outward, backward, and inward
- Complete 5 circles in each direction per leg
- Make the circles as large as comfortable
Running relevance: As covered in the hip CARs description in the external rotation of hip article on this site, hip circles (controlled articular rotations) develop the active range of motion that the hip requires during running, particularly during the swing phase.
Exercise 4: Walking Knee Hugs
Purpose: Activates the gluteus maximus and stretches the hip external rotators through a walking movement pattern that builds proprioception alongside mobility.
How to do it:
- Walk forward
- With each step, bring one knee up toward the chest and hug it for a brief moment (1 second)
- Release and step forward onto that leg
- Alternate knees with each step
- Complete 10 repetitions per leg (20 total steps)
Running relevance: The brief hip flexion hold activates the hip flexors and glutes in the single-leg position, and the standing balance component prepares the proprioceptive system for the repeated single-leg loading of running.
Exercise 5: Walking Quad Stretch
Purpose: Mobilises the hip into extension (the position reached during running push-off) while stretching the rectus femoris briefly.
How to do it:
- Walk forward
- With each step, lift one heel toward the buttock and briefly hold the ankle
- The momentary held position stretches the quad and hip flexor briefly without the prolonged static hold that reduces force production
- Release and step forward
- Complete 10 repetitions per leg
Running relevance: The brief quad stretch in the single-leg balance position replicates the hip extension of the push-off phase while developing the balance and coordination needed for running.
Exercise 6: Walking Lunge
Purpose: Activates the quadriceps, hip extensors, and hip flexors through the lunge pattern. Builds the eccentric quad control needed for the loading response of each running stride.
How to do it:
- Walk forward with an exaggerated lunge stride
- Step forward and lower the back knee toward the floor
- Drive through the front heel to rise and step forward into the next lunge
- Maintain an upright torso throughout
- Complete 10 lunges per leg
Running relevance: The walking lunge’s eccentric quad demand and the alternating single-leg loading pattern directly mimic the loading mechanics of running at a slower, more controlled pace.
Exercise 7: High Knee March
Purpose: Activates the hip flexors and glutes in the exaggerated knee-drive pattern. Warms up the hip flexors for the swing phase of running.
How to do it:
- Walk or march forward with exaggerated high knee drives
- Each knee drives up to at least hip height
- The arms pump in opposition to the legs (left arm with right knee)
- Focus on a deliberate, powerful knee drive rather than speed
- Complete 20 metres of high knee march
Running relevance: As covered in the exercise for psoas muscle strengthening article on this site, the psoas is the primary driver of the swing phase of running and specifically of high-speed knee drive. High-knee marching directly activates the psoas before the run.
Exercise 8: High Knee Skip
Purpose: Adds a plyometric element to the high knee pattern, developing the elastic response of the leg alongside the hip flexor activation.
How to do it:
- Skip forward with exaggerated high knee drives
- The skipping motion adds a small hop on each step, creating a brief flight phase
- Arms pump in opposition
- Focus on the height and power of each knee drive
- Complete 20 metres of high knee skipping
Running relevance: The brief flight phase of the skip requires the landing leg to produce elastic energy return during ground contact, preparing the Achilles tendon and calf for the spring-like demands of running.
Exercise 9: Butt Kicks
Purpose: Activates the hamstrings through the knee flexion pattern. Warms up the knee flexion component of the swing phase and the hamstring deceleration function.
How to do it:
- Jog forward with the heels kicking up toward the buttocks
- Focus on a rapid heel lift (knee flexion) rather than forward speed
- The movement emphasises the backward kick more than forward knee drive
- Complete 20 metres of butt kicks
Running relevance: As covered in the prevent hamstring injuries article on this site, hamstring activation before running is an important component of hamstring injury prevention. Butt kicks activate the knee flexion function of the hamstrings in a running-specific movement pattern.
Exercise 10: A-Skip (Coordination and Power)
Purpose: Combines the high knee drive with a skip rhythm, developing the coordination and neuromuscular timing that translates to running efficiency.
How to do it:
- Skip forward with an exaggerated high knee drive on each skip
- The lead knee drives up sharply while the opposite arm drives forward
- The skip rhythm creates a brief flight phase between each knee drive
- Focus on the precision and timing of the movement rather than speed
- Complete 20 metres of A-skips
Running relevance: The A-skip is used by sprint coaches as a fundamental running mechanics drill because it specifically develops the hip drive timing that produces efficient running. Including it in the warm-up primes the running mechanics before the run begins.
Exercise 11: Lateral Shuffle
Purpose: Activates the gluteus medius and hip abductors in the lateral direction, preparing these muscles for their stabilising role during the single-leg stance of running.
How to do it:
- Assume a slight squat position with the feet shoulder-width apart
- Shuffle laterally for 10 steps in one direction
- Shuffle back for 10 steps in the other direction
- Maintain the slight squat throughout
- Complete 2 sets per direction
Running relevance: As covered in the monster walk resistance bands article on this site, lateral movement activates the gluteus medius in the combined abduction and flexion pattern most relevant to the running stance phase.
Exercise 12: Progressive Acceleration Runs
Purpose: The final component of the warm-up. Progressive accelerations from walking pace to near-running pace prepare the cardiovascular system and the running-specific neuromuscular patterns for the main run.
How to do it:
- Begin with a 40-metre run at 60 percent effort
- Rest briefly (30 to 45 seconds) and perform a 40-metre run at 70 percent effort
- Rest and perform a 40-metre run at 80 percent effort
- For most easy runs, stop here. For speed sessions or races, add a 90 percent effort run
Why progressive accelerations are essential:
The exercises above prepare the muscles and joints for running. The progressive accelerations prepare the cardiovascular system and the running neuromuscular patterns at progressively higher intensities. Beginning a run immediately after the drills without the acceleration runs still leaves the body unprepared for running’s cardiovascular demands.

- Walking knee hugs: 10 per leg
- High knee march: 20 metres
- Butt kicks: 20 metres
- One progressive acceleration at 60 percent: 40 metres
Speed Session or Tempo Run Warm-Up (Full Version Plus)
For speed sessions, tempo runs, or race pace work that demands maximum neuromuscular preparation:
Complete the full routine above, plus:
- Add A-skips (second set) at maximum effort
- Add 4 progressive accelerations (60, 70, 80, 90 percent)
- Include 2 to 3 strides at near-race pace (100 metres at race pace effort)
Race Day Warm-Up
For races (5K, 10K, half-marathon, marathon):
5K and 10K: Full routine plus strides at race pace effort. Total time: 15 to 20 minutes before race start.
Half-marathon and marathon: Abbreviated routine (5 to 6 minutes) because the race itself begins at a sustainable aerobic pace. The full routine is most important for shorter, higher-intensity races.
Programming
For all runs: Perform the routine before every run, including easy recovery runs. The habit of warming up consistently is more important than the specific routine used.
Before running is cold: If running first thing in the morning or after a long period of sitting, spend an additional 2 to 3 minutes on lower body mobility (hip circles, leg swings) before beginning the structured routine.
Indoor running (treadmill): Perform the standing exercises (leg swings, hip circles, knee hugs, quad stretch) before stepping on the treadmill. The linear drills (high knee march, butt kicks, A-skip) can be replaced with treadmill walking at a brisk pace for 3 minutes as a transition.
Frequently Asked Questions
How long should a dynamic warm-up be before running?
The full routine described here takes 6 to 8 minutes. Research on warm-up duration suggests that 5 to 10 minutes of dynamic preparation is optimal for most running contexts. Shorter (3 to 4 minutes) is appropriate for easy runs. Longer (10 to 15 minutes) is appropriate before races and high-intensity speed sessions. The key is that the warm-up should leave the body primed and slightly elevated in heart rate without producing fatigue.
Should I stretch before running?
Dynamic stretching (as in this routine) is appropriate before running. Prolonged static stretching (holding positions for 30 to 60 seconds) is not appropriate immediately before running as it can temporarily reduce muscle force production and tendon stiffness. Save static stretching for post-run, when it is both more effective for flexibility development and does not interfere with running performance.
Can I skip the warm-up if I am running slowly?
Even easy runs benefit from a minimal warm-up because the first kilometres of any run at any pace place significant demands on cold, unstiff joints and unactivated glutes. The most common time for early-run injuries and discomfort is the first 10 to 15 minutes before the body is properly warmed up. A 3 to 4 minute minimal warm-up before even the easiest run reduces this early-run discomfort and risk.
Does the warm-up change the running performance?
Research on warm-up effects on running performance consistently shows that a dynamic warm-up improves early-run performance compared to no warm-up, particularly for the first 5 to 10 kilometres when the body would otherwise be gradually warming up during the run itself. For easy training runs, the performance effect is modest. For races and time trials, a proper warm-up is one of the most reliable free performance gains available.
