As I try to lead an active life by exercising regularly, I read every article in my hands to find out what I can and should do to improve my performance and, of course, keep those persistent little books at bay. And something that athletes, doctors, and scientists don't seem to agree on is when the stretch should be performed, or even whether or not it is necessary.
A few years ago, the idea that stretching should be done before an aerobic or strength training session was more widespread, and it is still quite common to see many people stretching before going for a run. However, there are experts who claim that stretching before warming up can lead to muscle or joint injury, so they recommend stretching after exercises. In this way they ensure that it can help increase flexibility, contribute to recovery and decrease the effects of lactic acid on the body.
After considering the different opinions and taking into account what I can demand of my little body, I have chosen what seems to me the safest way: to do a brief five-minute warm-up before running or exercising with weights, either with jumps in place or smooth movements of the arms and legs, and with flexions of the waist. Only at the end I do a slight stretch of the arms and legs, trying not to force them too much.
