MK: You mentioned the sumo deadlift. What are your thoughts on the sumo deadlift as opposed to the conventional stance?

MR: As I said, the sumo is a way to increase the verticality of the back angle. This shortens the moment arm between the hip and the bar by effectively shortening the length of the femur when the stance width is increased and by shortening the moment arm between the hip joint and the scapulas when the back angle is made more vertical. It is interesting that there are some people who can’t deadlift efficiently with a conventional stance. For example, some people have femurs and tibias that are so long relative to their back length that they can’t get their back angles much above horizontal without a stance that sufficiently shortens the effective femur length. We found a woman at one of our seminars whose femurs were four inches longer than her back. She had never been able to deadlift conventionally without having the bar ten inches in front of her mid-foot at her start position. When she was in the conventional stance with the bar over her mid-foot, her hips were actually much higher than her scapulas. We put her in a sumo stance, and she got her back at what would be a normal angle for a more proportioned person. She set a PR in her deadlift by 10 kg that day.
