Should You Stretch Before and After Strength Training? A Physical Therapist Explains the Effective Timing
Conclusion
“If I start strength training, should I also do stretches?”
Many people have this question.
To give you the conclusion first, you should stretch, but it is important to change the timing depending on your goal.
Before strength training: Dynamic stretching (performed while moving the body)
After strength training: Static stretching (stretching slowly)
Using these two types appropriately leads to safer and more efficient training.
In this article, from the perspective of a licensed physical therapist, I will explain recommended stretching methods for strength training beginners in an easy-to-understand way.
Why is stretching important?
Stretching plays a role in making it easier to move muscles and joints smoothly.
When muscles are stiff, it becomes difficult to maintain proper form, and you may not be able to provide sufficient stimulation to the targeted muscles.
Also, if you force yourself to train while your range of motion is limited, the burden is more likely to concentrate on specific parts of your body.
Especially for beginners, incorporating stretching makes it easier to continue strength training safely.
Perspective of a licensed physical therapist
In physical therapy, "muscle flexibility" and "joint movement" are considered the basics for moving the body efficiently.
For example, in a squat,
hip joints
ankles
thoracic spine
if movements like these are insufficient, your form is more likely to collapse.
If your form breaks down, the muscles you want to target won't receive sufficient stimulation, and you may place unnecessary strain on your lower back, knees, and other areas.
Stretching is not just for softening muscles; it is recommended to think of it as "preparation for performing training safely with proper form."
Dynamic stretching is recommended before strength training
Before strength training, dynamic stretching, which warms up muscles and joints while moving the body, is suitable.
For example,
shoulder circles
arm swings
leg swings
lunges
light squats
are recommended.
Performing dynamic stretching makes it easier for your body to move and prepares you for training.
Static stretching after strength training
After training, static stretching, which involves slowly stretching muscles without bouncing, is recommended.
The guideline is about 20 to 30 seconds per muscle group.
Do not hold your breath, and perform the stretches within a range that feels comfortable.
Stretching after training helps with relaxation and maintaining or improving flexibility.
What does research say?
Research has reported that performing long-duration static stretching before strength training may temporarily decrease muscle force production.
On the other hand, dynamic stretching is expected to improve performance as a warm-up.
Also, while static stretching after strength training is effective for maintaining flexibility and relaxation, the results regarding its effectiveness in significantly reducing muscle soreness are inconsistent.
Therefore, for beginners,
remembering the basic rule of 'dynamic before, static after'
is sufficient.
Using a foam roller is also recommended
In addition to stretching, self-care using a foam roller is also recommended.
Many people incorporate it as part of their post-workout conditioning or to support better body movement.
I personally use it for care after strength training or on days when I have been working at a desk for a long time.
Summary
For strength training beginners, making stretching a habit makes it easier to continue training safely and efficiently.
Here are the three key points:
Dynamic stretching before strength training
Static stretching after strength training
Do not overstretch
Stretching not only lengthens muscles but also helps in developing proper form and preventing injuries.
Please try incorporating it into your daily strength training routine.
