Exercise balls are more than just fun to sit and bounce on. They add variety, challenges and a new dimension to a workout routine—they’re a great way to improve strength, cardio endurance, and balance.
The ball will act as a surface, a weight, and an exercise machine in this workout, recruiting the abs, obliques, and transverse abdominis—a deep core muscle that’s critical to a strong midsection and pain-free back—which most conventional workouts leave untouched.
Shape the body you've dreamed of with this exercise routine,carefully selected to provide a maximum of efficiency and have fun while doing so.
