Whether it is running, swimming, weight lifting or aerobics, fitness experts say the center of all exercise routines is the core - the abdominal, back and muscles around the pelvis - which is the seat of stability, strength and power. Adding in exercise routines to strengthen the core can help the runner go faster, the basketball player jump higher and the everyday exerciser more easily do routine tasks from loading the car to cleaning the tub.
