Hyperextensions - Back Extensions
The hyperextension, also known as back extension, is a bodyweight exercise for the lower back muscles, where you lock your legs in a hyperextension machine and raise your upper until legs and trunk are in one line. Hyperextension are good for everybody who wants to train his lower back muscles. If you prefer heavier exercises. I recommend the barbell deadlift, which is better for maximum strength and muscle volume. However, people with back problems and or weak back muscles should stick with hyperextensions.
