Key facts
- Two main types: static and dynamic.
- Dynamic stretching suits warm-ups; static suits after training.
- Improves flexibility over time with consistency.
- Static stretching before lifting can briefly reduce power.
Stretching lengthens muscles to improve flexibility. Dynamic stretching moves a joint actively through its range and is ideal before training as part of a warm-up. Static stretching holds a lengthened position and is better suited to after a session or dedicated flexibility work.
Timing matters: long static stretches right before heavy lifting can temporarily reduce strength and power, so dynamic movement is the better pre-workout choice. Done consistently, stretching gradually improves flexibility, which supports mobility and comfortable positions — though for performance, mobility work that includes strength tends to carry over more.
Frequently asked questions
Should I stretch before or after a workout?
Use dynamic stretching before, as part of your warm-up, and save longer static stretches for after training, when they won't reduce performance.
Does stretching prevent injury?
The evidence is mixed. A proper warm-up and good mobility likely matter more for injury prevention than static stretching alone, though flexibility still has value.
