Been there, done that!
Having spent years in the gym, and having starved myself with every diet known to human species, I finally realized that no matter how many hours I spent on the treadmill, I would never achieve the body perfection I was after.
At the end of the day we all have different body structure, genes play the role too. Of course, staying fit and healthy is important, but I, like you, was looking for an instant fix, something that would make me feel like a million bucks in the snap of a finger. Being one of the many out there who loves looking good in a pair of jeans (but always kinda felt uncomfortable in them), I started experimenting with various undergarments. I noticed that my little inventions worked and I figured other brothers in need will benefit from the results.
