Superman Is Kryptonite For Your Lower Back

Disagree, disagree, and disagree again.  I'm a personal-trainer with over 10 years of experience.  The #1 exercise people suffering from lower back pain SHOULD do is the superman.  I've cured the back pain of numerous clients and I've always started them off with supermans.  Yes, you are right that if someone performs the superman to the degree that you show in your pictures, they will generate over 1300lbs of force and can cause further damage, BUT what your pictures are actually showing, and what you failed to mention, is the complete wrong way to perform the exercise.  The correct way to do the superman is to only lift your arms and legs off the ground 2-3 inches.  You start by holding the flexed position for 2 seconds for about 10 sets, and eventually build up to 30 second holds for 3 sets.  If anyone raises their legs, arms, and head as high as the individuals do in your pictures they are sure to hurt themselves.  Lastly, if you feel I"m wrong about this, please tell me how I've cured the back pain of several clients by having them perform an exercise that is "kryptonite" for their back.
