The core is the bridge of muscles between your upper and lower body; left and right sides. It helps correctly position your body in order to transfer power between your legs and upper body to produce an efficient motion. If there are any problems during the transfer of power, your chance of injury increases. A well-functioning core protects your spine, hips, knees and ankles and creates a fluent and efficient movement.

Try these exercises to help strengthen your core:

Twist

  1. Start in a seated position, with knees bent and feet raised off of the floor.
  2. Keep back straight and shoulders pulled back; hold a medicine ball or a weight plate out from the chest.
  3. Alternate twisting from right to left, bringing the ball or plate down toward the hips during each repetition. Keep the ball in front of the chest throughout the movement
  4. To modify: Repeat the exercise from a standing position. Standing with ankles, knees and hips slightly bent and trunk stabilized will simulate many sport-specific movements.
