Here's what we have learned over the last several years. Dynamically stretching before activity is important-Five Star Fitness Boot Camp vets know what this means: Butt Kickers, High Knees, Side Shuffles, Jack Squats, med ball tosses etc. Static stretching is reserved for the end of the workout.
Remember this: Dynamic Warm prepares the muscle for activity. Static Stretching prepares the muscle for rest.
