Does strength training limit flexibility?

According to Sang H. Kim, author of Ultimate Flexiblity, the idea that strength training makes you less flexibile is a myth. "Just the opposite is true," he says, "thanks to the stretch-shortening cycle. A very simple description of the stretch-shortening cycle likens it to an elastic band. When you stretch the elastic, it becomes taut and ready to snap back with force when released. The more pliable the elastic and the farther you can stretch it, the more force it will generate when released." A detailed explanation of the reasoning behind coordinating your strength training with a good stretching program can be found in chapter 2 of Ultimate Flexibility.
