Somewhere along the way, stretching became a religion with no scripture. The research is actually quite clear and quite awkward for the dogma: holding static stretches before explosive or heavy work can temporarily reduce power, while dynamic warm-ups genuinely cut injury risk. After training, static stretching is fine and useful for range of motion — just not for the reasons most people think. This guide sorts pre-workout from post-workout stretching and gives the five-minute habits that actually move the needle.
Static stretching before sport is mostly useless — and sometimes harmful. Here is what the evidence says about warming up, cooling down and flexibility.
Do dynamic movements — leg swings, lunges, arm circles — specific to what you are about to do. Save long static holds for after, since they can temporarily reduce power and strength.
A proper dynamic warm-up is associated with fewer injuries; static stretching alone is not. Warm muscles and prepared joints are what protect you.
For increasing range of motion, 30-60 seconds per stretch, repeated 2-3 times, several days a week. Brief 10-second touches do very little.
