Legs are important, even if your jeans hide them. These are the strongest and most important muscles in your body. Without them, you can't walk, and most importantly, you're not strong. Building your legs can be frustrating at first, but the results will be well worth it. This workout app will help to shape and define your legs.

You'll build all of the muscles needed to become well-defined: your glutes, hamstrings, and calves. You can do these exercises with most of your clothing on if that's what you want, and there's no reason to sweat too much.
