I am passionate eaters, like cricket and like to drink sometimes a beer. Therefore, I did it not so with diets. In the office I move micht too little, and sport doing less and less. At 1.80 and approximately 100kg liveweight you see me also to something. Therefore, I ordered this Bauchweg undershirt to hide my "problem zone belly" something. I have the undershirt ordered in size XL and then unfortunately had to find that it only helps very little. My girlfriend thinks that you can already see a difference. I personally felt the Bauchweg effect than low. In addition, I have a relatively broad cross and beginning tweaked it up a little rum side, below the armpits. By the time He did, because I have got used to it and the shirt also stretch slightly. 100% undetectable undershirt was however at no time. So I would not want to constantly wear. Whether it moves in the belly better in size L, I can not say, but there in XL to the chest is a little tight, I have refrained from an exchange.
