The Ooof ball takes medicine ball training beyond its normal applications. The OOOF Ball differs from the traditional leather medicine ball in several ways.
Some balls require inflation of air.
Many times the balls do not stay fully inflated during use, decreasing their effectiveness and function. An optional added piece of equipment, the air pump is also required with these balls. These weights can shift or if the covering breaks, you've got a mess to clean up and no way to fix the ball. Some balls don't bounce, decreasing the ways in which they can be used. An added piece of equipment such as a rebounder board may be required.
