The Balloon Sweep is an intermediate to advanced sweep to utilize but an important concept builder for beginners.
Against a skilled opponent this sweep can be very, very difficult but the setup is important because it builds perception of weight distribution. Specifically your opponents weight rocking forward onto your hips.
If you hit this sweep correctly it should feel almost effortless. The problem is the window of success is so small that often people will practice this 200-300 times
