RocketArm training system

does anyone have, or have used the RocketArm training system? and if so what are your thoughts on it

i have not but i can assure you , you will get the same results from using light free weights and resistence tubing doing RC exercises . gimmicks like that are just for people who dont know any better , granted it probably does help but you dont need to buy THAT to get THAT help. Again light free weights and res. tubing is for the same purpose
