Just go to the website of US amazon (amazon.com) to see that this product has 500 recommendations and ... 5 stars !! I wanted what was best, and I'm not disappointed. Certainly there is no DVD but an access code, you can watch many online videos and brochure shows many exercises to perform. An attachment system allows you to use a door as corner mounting and can replace all the movements you could do on a pulley on all desired heights. There are straps for the ankles, to work the legs and glutes, which most competitors do not offer. The carabiner hook system allows to double the elastic to increase strength but also to use other accessories such as XBAR (EZ curl bar) and offer many more possibilities like the squat and so on ... One thing beast but the weight is indicated on the elastic, no need to learn by heart the weight color association. It took me some time to find what I wanted but it is for me to have elastic THE!
