A neck hump, often called a “buffalo hump” or postural hump, can develop due to poor posture (especially forward head and rounded shoulders), muscle imbalance, excess fat accumulation, osteoporosis, or certain medical conditions, and long-term slouching can make it more noticeable by tightening chest muscles and weakening the upper back. Exercises like chin tucks (to align the neck), shoulder blade squeezes (to strengthen upper back muscles), wall angels, and upper back stretches can gradually improve posture and reduce its appearance when done consistently 4–5 times per week. Most people may notice small improvements in posture within 3–4 weeks, but visible changes in the hump’s appearance often take 8–12 weeks or more, depending on the cause and consistency of corrective exercises.
