Lower body is my absolute favorite thing to work out in the gym, or even at home. Legs and glutes respond really well to weights and body weight exercises, making them easier to do anywhere. When I played sports in high school, my favorite exercises to do in the gym were definitely lower body. I liked knowing I could move that much weight around easily. I wasn't a very big person, at 5'3, 117 pounds, I was the next to smallest on my team. I could leg press double my weight at least. Deadlifts! Straight legged deadlifts target the glutes more than regular deadlifts, and are fantastic IF you watch your form. Main muscles targeted are the hamstrings.
