Barbell Sumo Romanian Deadlift is an intermediate barbell exercise for the gluteus maximus (glutes), with the hamstrings and adductors (inner thighs) assisting. Most lifters train it for 3 to 4 sets of 8 to 12 reps.
A compound lower-body hinge exercise performed with a barbell in a wide (sumo) stance and feet turned slightly outward. The movement involves pushing the hips back while maintaining a neutral spine and lowering the barbell along the inner thighs. The lifter then drives through the heels and midfoot to extend the hips and return to a standing position, keeping the bar close to the body and controlling the descent throughout the range of motion.
The sumo Romanian deadlift runs the classic RDL hinge from a wide stance with the toes turned out, which drags the adductors and glutes into work the narrow version mostly leaves out while still loading the hamstrings through a long eccentric. It suits lifters who feel conventional RDLs only in the lower back, sumo pullers who want stance-specific hamstring volume, and anyone building the inner thigh without a machine. Program it 3 to 4 sets of 8 to 12 reps on lower days, after the main pull or squat.
Load it like an RDL, not a deadlift: most lifters start around 40 to 60 kg and progress in 2.5 to 5 kg jumps while the bar stays glued to the thighs. The range is shorter than a narrow RDL because the wide stance meets the stretch sooner, so judge depth by the inner thigh and hamstring tension, usually just below the knees, rather than by plate height. A 3 second descent and a one second pause in the stretch make moderate weights brutally effective, and the knees must track over the toes the whole way down or the adductor emphasis disappears.
Stance and emphasis. The wide, toes-out stance adds adductor and glute work and shortens the range, while the narrow RDL stretches the hamstrings further. They complement each other across training blocks.
That is the point: hinging from a wide stance lengthens the adductors, which also extend the hip. Expect noticeable inner thigh soreness the first few weeks.
To the depth where the hamstrings and inner thighs reach a strong stretch with a flat back, typically just past the knees. Forcing RDL depth from a sumo stance usually just rounds the spine.
