The other machine that i really have mixed feelings about is this machine below called the butt buster - and it really is that - you are on your hands and knees pushing weight up - anyhow the entire time i am on this machine i am thinking about how great it will be to be done - but it is the same thing once i am done i am happy that my rear end is tightening up - so that is why i do it even though i hate it so much
