BOSU ball is unstable ball which stands for BOTH sides up, is a fitness training device, invented in 1999 by David Weck, consisting of an inflated rubber hemisphere attached to a rigid platform. The device is often used for balance training. When the dome side faces up, the BOSU ball provides an unstable surface while the device remains stable. This combination of stable/unstable allows a wide range of users, from the young, elderly, or injured to the elite level athlete. With the dome side up, the device can be used for athletic drills and aerobic activities. As the name suggests, the device can also be flipped over so that the platform faces up. In this position, the device is highly unstable and can be used for a wide array of exercises as well.Benefits of bosu ball

Guidelines for bosu ball
1. The bosu is sensitive to extreme cold and extreme heat. It should not be stored near any heating
device. If you are leaving it in a car for more than an hour in cold weather, you will need to deflate the
2. Beginners, who have not yet developed adequate core strength, may be tempted to compromise form and over-compensate for weak core muscles by using larger muscle groups. This defeats the purpose of the exercise.
3. Exercising on the bosu requires extreme concentration. Without it, you risk slipping off the device and incurring an injury.
4.If you tend to sweat, perspiration accumulating on the ball can cause you to lose your balance. People with weak ankles may find that their ankles twist when stepping on and off the platform side.
