The Bender Ball is a 6-8″ inflatable ball that increases your core engagement up to 4 times more than floor crunches.
You can increase your workout intensity by extending back on the ball further. In the Bender Ball workouts, you can also choose the intensity and tempo that feels comfortable for you. Just by changing the leverage of your body, you can change the intensity of the workout. The intensity may also be adjusted by slightly inflating or deflating the ball. Other small balls, like a child’s toy ball, are not designed to be adjusted in this way.
