If you could choose only one exercise to add to your workout, that would be deadlifts. Yes, if you had the (unreal) possibility to do only one exercise, you couldn't choose better. This is absolutely the most complete exercise that you can imagine, because it involves a full body workout. It trains your upper body and lower body like no other exercise available. Correct deadlifts form. Quads, glutes, hamstrings, back, lower back, forearms, traps, rear deltoids, core...almost every muscle group is worked with this exercise. Think of deadlifts as a squat, only the barbell is in your hands instead of being on your shoulders.
