Using something like Andy Bolton's 457.5kg deadlift as reference here:
Is that a good distance to have your butt off the ground before you start? I tend to start with my butt quite a bit lower and then drive with my legs throughout the lift. Is it more efficient doing it the way Andy does it here, with the legs not even being very bent at starting position? Or is it different for everyone? I just want to be able to deadlift the most weight possible haha.
