Here’s an article I wrote a while back on Bullz-Eye.

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 strengthens 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.

Some say the squat is the king of all leg exercises. They even go as far as saying that if you don’t squat, your chances of building big, strong legs are next to impossible. And there are others who even take it one step further, claiming the squat is the best overall exercise there is period, and no routine should be without one.

Yes, I agree that the squat is unquestionably a very productive exercise in that it works a large number of major muscle groups. More so than any other exercise, however, it is not essential to do the barbell squat in order to get muscular and strong legs.

I do believe the squat is a very effective mass and strength builder, but for some the pain it causes due to injuries or anatomy makes this exercise very uncomfortable. An example of anatomy getting in the way are those who have very long legs and short torsos. These individuals have a very hard time being successful with this movement due to poor biomechanics. Some people need alternatives. But, if you want to learn how to perform the barbell squat properly and how to change what muscles are emphasized, go here.

Like the squat, the deadlift involves the largest muscle groups in the body: the gluteus maximus, hamstrings, quadriceps and erector spinea. And like the squat, it is a very hard, taxing exercise to perform. Consequently, for this reason alone many people don’t use the deadlift in their routines.

The gluteus maximus is utilized most in the beginning of the movement when there is a large degree of hip flexion. The glutes work in unison with the hamstring to extend the hips. The hamstrings, located on the back of the upper thigh, become more involved as you begin to decrease the degree of hip flexion as you raise 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. The quadriceps muscles are involved with knee extension.

Extension of the body occurs when the upper body, torso and pelvis rotate up and back. In a properly performed deadlift, this will happen simultaneously with the hips moving forward and the knees extending. Two of the biggest mistakes I see when this movement is performed are locking the knees out before the upper body is extended or 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 the hunch back of Notre Dame while performing the exercise that’s a different story.

The main reason your lower back would round, which could cause devastating trauma to the lumbar area, is weak erector muscles. There are various exercises you can use to strengthen your lower back like good mornings, arched back good mornings, arched back stiff legged deadlifts, and reverse hyperextensions, but good mornings and its variation in my opinion are probably the best exercise for this purpose.??????
