Ejercicios de Glúteos, Tríceps y Pectorales en Fit Ball.

If you've been stepping up your core workout with a fitball or a BOSU, it may be time to increase the intensity by combining the two. Designed to improve your core strength, stability and balance, the BOSU--which stands for "Both Sides Utilized"--is a ball-like dome with a platform on the opposite side. Through blending the BOSU dome, platform and a standard fitball, you can create core exercises that challenge your body in ways you've never experienced.
