i ve a abking pro,obitrek platinum and f crs a sauna belt.none of these machines helped me to get my belly back to where it belongs,and if you stop using these machines after sevrl months all the things you ve gaind during past months will be gone.but one f my frnd is using a trade mill and only it.but sprsingly he is in good shape.he exrsise 30 mins per day.im also goin to buy a one but they are very expnsive,execd 40k.but worth the money.
go to ur trainer or doc and ask about how to do cardiac exercises using a trade mill.its the best way to burn calorie
