This has been discussed before, but I can't find the threads. I figure if we make this thread better than those other ones then ΔG will be negative.
I still can't figure out how to deadlift with a belt. When I wore the belt at the third hole, the belt was too loose when I would get into the bottom position of the deadlift. When I wore the belt at the fourth hole (i.e. tighter) the belt would either get shoved into my ribs or pinch my abdominal fat at the bottom position, depending on how high up the belt was on my torso. Both of these cases are painful. What am I doing wrong?
