Biomechanical analysis of elite powerlifters showed that these athletes produced significantly less force in the starting position compared to other positions of the deadlift. Train exercises like deficit deadlifts and speed deadlifts to improve your strength and power off the floor to overcome this weak position. Mobility work may also be necessary for novice lifters to be able to safely and adequately produce force in this position.
