10 Min Exercise Ball Workout: Core-Strength Moves Using A Fitness Ball (Premium) - Tone Up And Slim Down app for iPhone and iPad

Swiss balls are more than just fun to sit and bounce on as they add variety, challenge and a new dimension to a routine—they’re a great way to improve vitality, cardio endurance, and balance.
The ball will act as a surface, a weight, and an training machine in this workout, recruiting the abs, obliques, and transverse abdominis—a deep muscle that’s critical to a strong midsection and pain-free back—which most conventional routines leave untouched.
Shape the body youve dreamed of with this training,carefully selected to provide a maximum of efficiency.
