very well even if it's hard!

I read all the reviews before buying, and it is consistent with what is said. By cons, 5 minutes, that's impossible, I'm 3 minutes or so, after a little over a week. But there was still a clear and flagrant improvement: at the beginning I could do that 5 movements. (Yes I count the minutes no movements). Today I actually 40 even if the last five are deadly!
Abs really reinforce vites before when I contractais, it was soft (but really), my brothers always ask me how do I survive without muscles :) And now it is clearly hard! by cons, visually, I do not see anything changing. Back muscles also work great (wrist love).
On the machine itself, installation in 5 minutes, still quite heavy packages, foams for the knees and arms are perfect, I am afraid they are all fine, not at all, no pain on members of support. In practice, apart sore abs after my 35 movements, we did not hurt the back, the back remains very very ergonomic right! I have co-bought one for my mother, my brothers were not convinced and found it a bit strange "what you got yet been bought, did you see it on TV: it does not work is the m **** ". Result, they have drooled when they tried it, and now they use more than my mother (lol).

I really recommend it ranks 1 minute, takes no space tidy! and we feel the results quickly, after I do not know how long they are clearly visible on the abs for women (it is known that men take more vites muscles than women).
