I am in my 2nd week of using it every week... am up to intensity of 65 for 35-40 mins
I think it does work as my waist is dropping inches a lot faster than anywhere else.
I was told that when you are still covered with fat, the changes don't show as the fat covers the muscles but it still does tone the muscles which are revealed when the weigh finally goes...
For me I have a bad back and have to be extremly careful with exercise, and couldnt every do sit ups.. so for me it is an option I am using to the full,, i suppose only time will tell though if it really really works...
