A powerful core diminishes loss of momentum as energy is transferred from the lower body to the upper body and vice versa. This helps you fight fatigue, generate more power and do everything better; from sitting and standing to running and jumping. The Two Minute Plank workout helps you get exactly the kind of core that makes you feel you can go on forever. Add EC and you're on your way to your fitness goal.
Extra Credit: Keep the plank all the way, don't drop down.
