These days, you hear a lot about being "quad dominant." There's good reason for it, too: Our compulsive focus on training the muscles we see in the mirror, poor form in movements like a squat, and our desk jockey culture all add up to quads that are typically tight and overused. But too often the knee-jerk reaction is to avoid training the quads altogether, and simply focus on the butt and hamstrings to re-create body balance. That dismisses the idea that tight muscles can still be weak. Instead of ignoring the quads, use proper training and stretching techniques to improve their muscle quality, and set the stage for strong, balanced, healthy legs. Here are the top exercises to do just that.
