Although very simple, balance exercises can greatly strengthen your center of gravity. Any exercise that is done on one leg can be considered a balance exercise. Standing on one leg will improve your body's ability to center its mass over one leg.
These are known as planche push-ups. To do this variation, the body's center of gravity must be kept over the hands while performing the push-up by leaning forward while the legs are elevated in the air, which requires great strength and a high level of balance. The entire body weight is lifted in this variation.
