Squats are great for building lower-body strength. The simple move targets a bunch of muscles, but you usually feel it primarily in your quads (front thigh muscles) and glutes (butt muscles).
Tweaking your squat form can have an impact on all kinds of things, including where you feel the move and the type of strength you build. For example, jump squats can help you build explosive strength, while doing a squat hold will improve your muscular endurance.
