Stretching before or after exercise: what works
Dynamic first, static later
Coach Julien Marest
Exercise physiologist
In simple terms
Long holds before effort can reduce power; save them for the cool-down.
Two very different kinds of stretching
Dynamic stretching means moving through a range of motion: leg swings, arm circles, walking lunges. Static stretching means holding a position for 20 to 60 seconds.
Before exercise
A warm-up should raise your temperature and rehearse the movement you are about to do. Five to ten minutes of easy cardio plus dynamic movements does that. Long static holds just before a sprint or a heavy lift can temporarily reduce force output, so keep them short if you use them at all.
After exercise
This is where static stretching fits naturally. It will not prevent muscle soreness, but it feels good, helps you wind down, and maintains flexibility over months when done consistently.
Does stretching prevent injury?
On its own, not much. What does reduce injuries is strengthening the muscles around the joint, progressing training load gradually, and sleeping enough. Flexibility work is a useful complement, not a shield.
