You SHOULD stretch!
Don't be confused by articles and studies about the negative effects of stretching before athletic performance. These studies do not negate the positive effects and need for flexibility training. If you are about to sprint or squat YES stretching can have a negative impact on your performance. This does not mean that you should never stretch!! If you remove mobility and flexibility from your practice you are limiting your capacity to to move freely. A body that is ridged is not free and not strong. Shawn Mozen
