The erector spinae (/ ɪ ˈ r ɛ k t ər ˈ s p aɪ n i / irr-EK-tər SPY-nee) [1] or spinal erectors is a set of muscles that straighten and rotate the back. The spinal erectors work together with the glutes ( gluteus maximus , gluteus medius and gluteus minimus ) to maintain stable posture standing or sitting .
It is known as a good-morning because of the movement in the erector spinae which resembles the bow that traditionally begins a schoolday in some East-Asian countries. The erector spinae muscles of the lower back work isometrically to keep the spine in an extended position while the hamstrings and gluteus maximus work isotonically to perform ...
A back extension is an exercise that works the lower back as well as the mid and upper back, specifically the erector spinae muscles. There are two erector spinae, one on either side of the spine, that run along its length. These are formed of three smaller muscles – spinalis, longissimus, and iliocostalis. [1]
The thoracolumbar fascia (lumbodorsal fascia or thoracodorsal fascia) is a complex, [1]: 1137 multilayer arrangement of fascial and aponeurotic layers forming a separation between the paraspinal muscles on one side, and the muscles of the posterior abdominal wall (quadratus lumborum, and psoas major [1]: 1137 ) on the other.
Boosting the production of collagen and elastin helps prevent stretch marks from occurring. [18] Stretch marks can also derive from nutritional deficiencies. Consuming foods that contribute to the skin's health, such as zinc-rich foods, protein-rich foods, and foods high in vitamin A, C, and D, can help suppress stretch marks. [19]
The primary exercises for developing the posterior chain are the Olympic lifts, squats, [1] good-mornings, bent-over rows, deadlifts, [1] pull-ups and hyperextensions. The common denominator among many of these movements is a focus on hip extension, excluding bent-over rows and pull ups. Working on hamstrings is also important.
Then, over the years, we were told it was better to stretch after exercise. Stretching can help make you more flexible, improve range of motion in your joints — and feel good.
