These intrinsics are primarily responsible for stabilising the spine when sitting or standing still and whenever you move a limb, Kelley said. They include the splenius capitis, interspinales, intertransversarii, spinal erectors, semispinalis, multifidi and rotatores. Muscles that sit a bit deeper and support your spine are collectively known as intrinsic back muscles. The rhomboids also kick in during exercises like a reverse fly and face pull (this involves pulling weight towards your forehead with a suspension trainer, resistance band or cable pulley while keeping your elbows high). ![]() These muscles pull the shoulder blades towards your midline, as when doing a bent-over row, Novak said. They sit beneath the traps and run from the spine to the edge of the shoulder blade. The rhomboids are two separate muscles in the upper back: the rhomboid major and the rhomboid minor. You'll work these muscles when you perform rows, pull-ups, shrugs and lat pull-downs. The traps allow you to lift and rotate your head, bring your shoulder blades in and down when maintaining upright posture, and twist your torso, noted the Cleveland Clinic. They start at the base of your neck, extend across your shoulders, and run down to the middle of your back. The trapezius, or "traps", are another pair of triangle-shaped muscles in your back. As such, the lats are heavily involved in exercises like pull-ups and lat pull-downs, and activities like rowing and swimming. Their main function is to internally rotate, extend and bring the arm towards the midline of the body (also known as adduction), said Jennifer Novak, MS, CSCS, owner of PEAK Symmetry Performance Strategies in Atlanta, Ga. They span from the upper arm (humerus) down to the pelvis and across the ribs. More commonly referred to as "the lats", these two triangle-shaped muscles take up most of the space in your back. They also help to move your arms and trunk in different directions. Essentially, they hold you up against the forces of gravity, said William Kelley, DPT, ATC, CSCS and owner of Aries Physical Therapy in South Florida. These muscles are always "on" to stabilise your spine. The muscles in your back are a group of postural muscles in the body. ![]()
