Yoga balls are all the rage these days, and there is good reason for it. A yoga ball forces your stabilizer muscles, like your abs, to work. With typical weight machines, you are able to isolate a muscle group without including your abs or other smaller muscle groups. This means that while you are improving the strength and endurance of the major muscles, your smaller muscles are suffering from atrophy.
Removing yourself from the solid surface of a bench or platform allows you to work every single fiber of your muscle. This insures a balanced look and an overall tone that looks and feels remarkable. Start with these 5 great exercises on the Yoga Ball to begin strengthening your muscle tone and looking even better overall.
