"DB Wide Row" typically refers to a dumbbell exercise targeting the upper back muscles, particularly the latissimus dorsi and rhomboids. In this exercise, you hold a dumbbell in each hand and perform a rowing motion with your elbows flared out to the sides, resembling a wider grip compared to traditional rows. This variation helps engage different parts of the back muscles, promoting overall back strength and development. The video would demonstrate proper form, technique, variations, and the benefits of incorporating DB wide rows into a comprehensive upper body workout routine to enhance posture, strength, and muscular balance.
