In the video "The Best & Worst Chest Exercises To Build Muscle (Ranked!)," the speaker ranks different chest exercises based on muscle-building effectiveness. He discusses the benefits and shortcomings of each exercise, including cable crossovers, which he finds to effectively target different parts of the chest, though they require more setup and weight progression can be difficult. The dip, incline dumbbell press, and machine chest press are among his favorites, while exercises such as the standing plate press and dumbbell pullover do not effectively target the chest. The bench press is ranked as the number one exercise for effectively overloading the pecs and placing high tension on them throughout a full range of motion.
