by Charles Poliquin Iron Man MagazineQ: Is it okay to stretch before a workout?
A: I get this question all the time, and the answer depends on the type of stretching. If you’re talking about static stretching, the answer is no. Static stretching temporarily weakens the muscles and as such increases the risk of injury.
Studies have shown that the resultant decreases in maximum strength and power range from 7 to 20 percent—and who wants to compete at only 80 to 93 percent?
Rather than doing static stretching, you can use ballistic (also known as dynamic) stretching before training. With this type of stretching, I prefer the pendulum approach, in which you gradually increase both the range and the velocity of the stretch.
