it work ! it do what it say . you need to be patient with it , and just like and piece of gym equipment , you have to learn how to use it . whereas I do not recommend this as a replacement for free weight , or you regular gym workout if that be what you be do , I do recommend it as a addition to they . if you do not have free weight , or do not have time to go to the gym , this will do very well . if you can get a 6 minute work-out out of it right away , why be you use it ? -lrb- LOL ! -rrb- seriously , take you time with it , go as long as you can , be patient with it , use all the different exercise routine that it show you how to use -lrb- the include dvd be pretty good , and the website have even more -rrb- , and work up to as long as you can . you will feel it immediately -lrb- A.K.A. sore at first , burn once you get the hang of it - and burn be a good thing ! -rrb- . the only thing I do have to say as a downside to this be the grip . it be a tad uncomfortable , and it get a little slippery when you start to sweat -lrb- and you will ! -rrb- I highly recommend a good set of workout glove with good rubber grip -lrb- Sears sell they - $ 18 -rrb- . other than that , use it regularly , and start slow , just as you would any other workout regimen , and work up to that 6 minute a day workout . no I do not look like the guy in the commercial - yet - but I notice a significant increase in my arm , shoulder , and abdomen muscle . use the dvd and website !! good stuff for $ 30 !
