Query: powerful workout

I thought at first this would be easy no problem, but i was wrong it is pretty easy, but it realy works you and pushes you, if want a good work out opposite the days you go to the gym here it is. awesome hardcore workout, really works very sore the next day, the only thing is i had to listen to my ipod while doing here workout much really is no the greatest, a good bargin for the workout you will get.
