Static stretching can weaken your workout

The problem with this article is that it is too vague.

Stretching is by far a very useful technique to prevent cramping in your muscles. That's what needs to be kept in mind. If you pull a muscle from not stretching before and after a workout, or even get a cramp can dampen your workout regimine, and if you pull a muscle or strain it a week to a few weeks can be lost until you can get back to 100% of your workout.

Researchers now believe that some of the more entrenched elements of many athletes’ warm-up regimens are not only a waste of time but actually bad for you.

I would completely disagree with this. There have been NUMEROUS times where I had not stretched before working out our playing basketball and noticebally pulled a damn hamstring, strained a damn calf muscle, or even just getting a cramp somewhere, which could have been easily prevented from stretching.
