NEVER HYPEREXTEND

99. NEVER HYPEREXTEND They are commonly called hyperextensions but in reality you should never hyperextend. One of the best exercises for the lower back muscles is to lie face down on a ball or back extension machine and then gently raise the torso upwards. You should only rise up until your upper body is in line with your lower, or just slightly beyond. Do not try to arch as high as you can. This places tremendous stress on the lower back ligaments. You can still call the exercise hyperextensions, but please don't hyperextend.
