the neck one only some...they will turn your head left and right
a few times before 1 swoop to either side ad you'll hear all the
kiiaaacckk..
the other cracking part is the back and spine there..twisting
your body to either side..
i dont enjoy the leg part though..never really fancied leg
massages..
i like backs...but shoulders are the killers for me. awfully
painful.
