what are you talking about ballapix? not anyone can use them, some claim 8 inches minimum but we know what the good ones are, i havent even finished my 12 week one and i have gained 8 - 10 inches. if u are overweight or have a medical condition then you shouldnt do them, unless ur physician says u can. and to the guys thats lyk 5'6 130 yeh thats fine to start.
