Working your midsection

FRESNO, Calif. (KFSN) -- Fitness expert Rhonda Murphy shows us some moves that will help you work all those muscles.

When working the core muscles, it is important to work front to back, side to side. You want to have an exercise routine that is less challenging at the beginning and you can increase the intensity as you get stronger.

For core-based workouts, you want to think about your body's circumference so each movement from side to side and front to back will target the core in a slightly different manner. For example, a modified plank focuses on the front part of the core but as you turn your knee in toward your midline you start to work the sides.

As you lift your arm up and turn your torso. The load on the muscle goes into the side and slightly to the back of the core. When you change the angle of your arms, you change the whole load on the core muscle. Engage the core and slowly control the move.

Try and change your workout about every month.
