Bodyweight alone is used to target your core and glutes - with an extra emphasis on your obliques.

Inner thighs and obliques are a perfect match for working on core stability. Use a pilates ball for this series that targets your adductors and sides of your waist.

This challenging core series uses a pilates ball to target both your deep abdominal muscles and obliques.

Work your arms and abs from every angle in this 15 minute class.

Arms & Abs - name a better duo. This 15 minute video combines upper body and 360 degree core work using a set of light weights and a pilates ball.
