Sumo deadlift
From Wikipedia, the free encyclopedia
The sumo deadlift is a variation of the barbell deadlift often adopted by powerlifters.
The difference between the two lies in the setup of the lifter's feet and hands. When the bar is gripped with the lifter's hands inside their legs, the form is considered "sumo". Traditionally, hip stance is far wider in sumo deadlifts, and toes are pointed slightly outwards.[1]
The sumo deadlift may be advantageous to people with exceptional hip mobility, a long torso, or short arms, as it allows the hips to start closer to the bar, with the torso in a more upright position.[2] Another advantage of the sumo deadlift is decreased shearing force on the lumbar spine when compared to the conventional deadlift. Other benefits of the sumo deadlift include: Strengthening the quadriceps, glutes, hamstrings, and other muscles of the posterior chain. In addition to building strength and muscle mass, the sumo deadlift can be used as a rehabilitation exercise to overcome back injury.[3]
