Forget the thigh gap—I'll take strong legs over skinny any day! The power of strong legs lies in the ability to simply move better. Think about how much you walk around, trek up and down stairs, and go from sitting to standing all day. To get you to peak performance in and out of the gym, check out the best types of exercises that build up strength in your thighs. In other words, while you can run around town as much as you want, or hit the elliptical too, you still have to pick up some weights if you want to strengthen your thighs. Focusing on functional movement patterns—think squat, lunge, push, pull—is the smartest way to train your legs. And squats are a top-notch way to specifically target your thighs, working degrees of your upper leg.
