Back Muscle Group
Back Muscle Groups include the Trapezius, Rhomboids and Latissimus Dorsi
The Upper Back consists of several different muscle groups, including the trapezius and rhomboids. The trapezius (known as "traps") is a large muscle group extending from the upper back down the middle of the back. Rhomboids is a large muscle group in the middle of the back. The Latissimus Dorsi (known also as "lats") stretch from the upper arm ot the lower back.
What Do the Back Muscles Do?
The upper back muscles, including the rhomboids and trapezius, hand much of the burden of lifting, and do much of the work rotating the scapula (shoulder blade). These muscles are normally one of the strongest muscles on the body because they are required for so much of our daily work. However, since rhomboids retract the shoulders, and elevate the shoulder blades, weak rhomboids can result in a decline of proper posture. Weakness in any of the major back muscles can result in bad posture.
