Bending over to pick something up can be a very dangerous move if done with a rounded back. Most people in their lifetime will have an injury to the lower back. One way to help prevent such injuries is to do the good morning.

Performing the good morning is an excellent choice for strengthening and building the posterior chain, which includes the lower back, glutes and hamstrings. The glutes (butt) and the hamstrings are responsible for hip extension while the muscles of the lower back (erector spinea) are contracted statically.

Because of the large degree of hip flexion, the gluteus maximus and the hamstrings are utilized throughout the movement. The glutes work in unison with the hamstring to extend the hips in the concentric (raising) part of the movement. The hamstrings, located on the back of the upper thigh, become more involved as you begin to decrease the degree of hip flexion while raising the weight. The erector spinea, which run the length of your spine on both sides, are statically contracted throughout most of the movement, keeping the normal curvature of the spine. A static contraction of the rhomboids and the trapezius muscles help maintain the shoulders.

Extension of the body occurs when the upper body, torso and pelvis rotate up and back. The biggest mistake I see with this movement is allowing the back to ?round? and magnifying the kyphotic (upper back) curvature while de-emphasizing the lordotic (lower back) curvature. I need to add that a slight curve of the upper back will present no danger and will happen to most while using heavy weight, but if you look like a big question mark (?) while performing the exercise, that?s a different story.
