Static vs Dynamic? When and why..

Ever since first grade gym class were taught static stretch before playing. You know, the while touch you toes and hold stretch and things of that sort. But now researchers are coming to the conclusion that static stretching before most intense activites is actually bad for you since it pre-exhausts your muscles making them weaker. This is where the dynamic stretching aka movement stretching comes into play. Things like leg swings, butt kicks, jumping jacks, which increase blood flow and range of motion in the areas you plan to use. Now there is still a time and place for static stretching at the end of workouts when your trying to recover but like the G.I Joes show, learning when to use them is half the battle.

Dynamic Stretching Examples:
Leg Swings
Body Weight Squats
Jumping Jacks
Butt Kicks
Arm Swings
Carioca
Speed Good Mornings
etc...
