The biceps are the show muscles of the body. To build them, we naturally think of weight-based exercises like the barbell curl, cable curls, and incline dumbbell curls. It’s no secret that a big upper back is important for being strong at just about anything. Although the biceps are relatively small muscles, that doesn’t mean that they should be paid any less attention. The back is the powerhouse of the human body. It provides structure, strength, mobility for every action we take.
