A fitness ball can be a great tool for toning your abdominal muscles (abs), as well as other core muscles.
Fitness balls — also known as stability balls — come in various sizes. Choose a fitness ball that allows your knees to be at a right angle when you sit on the ball with your feet flat on the floor.
To tone your abdominal muscles using a fitness ball, try the abdominal crunch:
Start with up to five repetitions, as long as you're able to maintain good form. Over time, as you strengthen your abs and core muscles, gradually increase to 12 to 15 repetitions on the fitness ball. Remember to breathe freely and deeply while using the fitness ball.
