Dynamic and static stretching are both useful. The better choice depends on the goal, the duration of stretching and what you are about to do.
Dynamic stretching usually fits well into a warm-up because it combines movement with preparation for sport or training. Static stretching is effective for improving flexibility, and short bouts do not automatically reduce performance.
What Is Dynamic Stretching?
Dynamic stretching uses controlled movement through a comfortable range. Examples include leg swings, walking lunges, arm circles and controlled hip-openers.
It is often useful before running, lifting, field sports or other activities because it can be integrated into a progressive warm-up.
What Is Static Stretching?
Static stretching involves holding a position at the edge of a comfortable range. It is one of the most studied methods for improving flexibility.
A large 2024 systematic review found both acute and chronic static stretching improve flexibility, with larger gains in people who start with lower flexibility.

Does Static Stretching Reduce Strength or Power?
It depends largely on duration and context.
An updated 2024 meta-analysis found a small reduction in isolated maximal strength after static stretching, with larger effects when individual stretch bouts lasted 60 seconds or more. However, the review did not find a general negative effect on athletic performance such as jumping or sprinting.
Read the 2024 review of stretch-induced performance changes.
So the old advice that “static stretching before exercise is always bad” is too simplistic.
When Dynamic Stretching Makes Sense
Dynamic stretching is a useful choice when you want to prepare for movements you are about to perform.
- before sprinting or running
- before field or court sports
- before weight training
- before jumping or explosive activity
- when you want to combine mobility with a warm-up
A 2026 systematic review found dynamic stretching produced small flexibility gains and small performance improvements, while longer static stretching produced larger flexibility gains but slightly worse immediate performance in some contexts.

When Static Stretching Makes Sense
Static stretching is useful when flexibility itself is the goal. It can be used:
- in a dedicated mobility session
- after training if you enjoy it
- before activity when short and relevant to the task
- as part of rehabilitation when prescribed appropriately
There is no requirement to save all static stretching for after exercise.
Dynamic vs Static Stretching Before Training
| Goal | Dynamic stretching | Static stretching |
|---|---|---|
| Prepare for sport-specific movement | Very useful | Less specific |
| Improve flexibility acutely | Small benefit | Moderate benefit |
| Before maximal strength/power | Usually suitable | Keep long holds limited |
| Dedicated flexibility work | Useful | Very useful |
A Simple Warm-Up Structure
- Raise body temperature: 3–5 minutes of easy movement.
- Use dynamic mobility: choose movements relevant to the session.
- Add short static stretches only if useful: especially for a range you specifically need.
- Progress toward the activity: use lighter sets, drills or accelerations.
- Avoid unnecessary fatigue: the warm-up should prepare you, not tire you out.
Does Stretching Prevent Injuries?
Stretching alone does not guarantee injury prevention. Injury risk is influenced by training load, strength, previous injury, sport demands, recovery and many other factors.
Stretching should therefore be one tool within a broader programme rather than the centre of an injury-prevention strategy.
What About Tight Muscles?
Feeling tight does not always mean you need more stretching. Sometimes strength, fatigue, training load or sensitivity are more relevant.
If muscular tension is limiting comfortable movement, our Sports Massage or Deep Tissue Massage services may help with short-term comfort.
Frequently Asked Questions
Is dynamic stretching better before exercise?
Often yes, because it prepares you through movement, but short static stretching can also be appropriate.
Should I avoid static stretching before lifting?
Not necessarily. Short bouts are unlikely to meaningfully reduce performance, while long holds immediately before maximal efforts may be less useful.
How long should I hold a static stretch?
There is no single rule. For flexibility training, longer total volumes can be useful; immediately before maximal strength or power, shorter bouts are more conservative.
Can dynamic stretching improve flexibility?
Yes, usually to a smaller acute extent than static stretching.
Should stretching hurt?
No. It should feel controlled rather than sharp or painful.
