Powerful quads translate the pull of the planet on the mass of your body into high-quality energy you can use for your own purpose. The legs of Steel challenge will help you level up by acquiring the kind of lower body strength that helps you stand, walk, run, jump and kick better. All you have to do is start one day one and come out transformed at the end of day thirty.
