Comments
"When doing this exercise with a barbell or dumbbell load, this is mostly equivalent to romanian (stiff-legged) deadlifts - except for minor differences in how the shoulders and lats are engaged as supporting muscles. IMO the ergonomics are better with this exercise. Leg stiffness is ensured by the machine, and you can safely place a barbell load back on the floor after the last repetition..."
"This exercise is actually called "back extensions", not "hyperextensions". In this exercise, the back is not (and should not be) hyperextended, ever. I don't know where this "hyperextension" name came from, it is wrong, but it somehow stuck."
