Immediately focus on your thighs, glutes, abs, pelvic floor, and other specific muscle targets. 2. Multi-use everywhere: The fitness ball is suitable for increasing abdominal strength and flexibility. Not only can they be used for exercise, but they can also be used as yoga ball chairs in a home office or classroom.
