this be not a bad price , and it come with a dvd to show you different way to use it and diffferent excersize technique but after about 3 month I get tire of it , just like any other work out equipment . I do not see much progress and I use it about 3-4 time a week but if you be the kind of person who work out 2-3 time a day 5-7 day a week this might work better for you . it sure do make my arm sore so I be sure it do something !
