A B-stance Romanian deadlift is a hip hinge you perform with most of your weight on one leg, while the toes of your other foot rest behind you like a kickstand. It sits neatly between the two-legged Romanian deadlift and the full single-leg version, handing you most of the single-leg training effect without the wobble that makes true one-leg work so fiddly. You load one hamstring and glute hard, keep your balance with a light back foot, and still get to use a decent amount of weight. It's one of the best ways to even out a stronger and a weaker side. Here's how to set it up, the muscles it hits, and how to program it.
Picture a normal Romanian deadlift, then slide one foot back so only your toes touch the floor behind you. That back foot isn't there to lift weight. It's a kickstand, taking maybe a fifth of your bodyweight so you can hinge over your front leg without toppling sideways. The front leg does roughly 70 to 80 percent of the work, which is why some coaches call this a one-and-a-half leg exercise.
The Romanian deadlift trains both hamstrings at once and lets you move the most weight. The single-leg deadlift isolates one side completely, but it turns into a balancing act that caps how heavy you can go. The B-stance splits the difference. You get the single-side focus that exposes and fixes a weaker leg, minus most of the wobble, so you can actually load the muscle rather than fighting to stay upright.
Why bother? Most people have one hamstring and glute that pull harder than the other, and a two-legged hinge happily lets the strong side take over. Training one leg at a time closes that gap. The B-stance is also the easiest unilateral hinge to learn, which makes it a sensible first rung on the ladder before you attempt full single-leg work.
You can hold a dumbbell or kettlebell in one or both hands. Start with a weight in both hands in front of your thighs while you learn the pattern.
Keep every rep slow and the stretch honest. Most of the benefit lives in that lengthened position, so rushing the lower just robs you of it.
The one cue that makes it click
Treat the back foot as a kickstand, nothing more. Keep around 75 percent of your weight planted through the front foot and let the back toes carry just enough to stop you tipping sideways. If you feel yourself pushing down hard through the back leg, you've quietly turned it into a normal two-legged hinge and lost the point.
The B-stance RDL is a posterior chain exercise, meaning it loads the muscles down the back of your body on the working side.
Deadlift-pattern moves load the hamstrings, though not maximally: one EMG classification placed the deadlift in the lower-intensity band for the semitendinosus, below moves like the Nordic curl (hamstring exercise EMG classification). Treat the B-stance RDL as a dependable staple rather than your single hardest hamstring move. For more ways to hit these muscles, see our guides to hamstring exercises and glute exercises.
Loading the back foot. This is the usual error. The second you press down through the back leg, both legs share the work and the lift stops being one-sided. Keep that heel high and the pressure feather-light.
Squatting instead of hinging. If your front knee keeps bending and your hips sink straight down, you're squatting. Lock in one soft knee angle and send your hips back instead of down.
Rounding your back. Letting your spine curl under the weight pulls load off the hamstrings and onto your discs. Keep your chest proud and a flat back from your head to your tailbone the whole way down.
Going too deep. Depth should come from your hamstring flexibility, not from bending further once the stretch runs out. When your lower back starts to round, you've gone far enough. Stop there.
Hips twisting open. The hip of your kickstand leg loves to rotate outward, which skews your alignment and lets the stronger muscles cheat. Keep both hip bones pointing at the floor like headlights, square to the front.
Any single weight works, but where you hold it changes the feel.
Strength work like this counts towards the muscle-strengthening the NHS suggests adults do on at least two days a week, alongside your other leg and hip training.
The B-stance RDL rewards control over heavy ego-lifting, so keep the reps moderate to high.
Always train your weaker side first and match the stronger side to it, not the other way round. If your left leg manages only 10 clean reps, cap the right at 10 too. That's how you actually level out a lopsided pair of legs over a few weeks, rather than letting the dominant side race ahead.
It's a hip hinge you do with most of your weight on one leg, while the toes of your other foot rest behind you as a kickstand for balance. The front leg does roughly 70 to 80 percent of the work. It sits between the two-legged Romanian deadlift and the full single-leg version, giving you single-side training without the big balance demand.
Neither is strictly better, they just trade off. The single-leg deadlift isolates one side completely but turns into a balancing act that caps how heavy you can go. The B-stance version keeps a light back foot for stability, so you can load the working hamstring and glute harder and focus on the stretch. Most people should learn the B-stance first.
As little as possible. Keep around 75 percent of your weight through the flat front foot and let the back toes carry just enough to stop you tipping sideways. The moment you start pressing down hard through the back leg, both legs share the load and the exercise stops being one-sided.
Mainly the hamstrings and glutes of your front leg, with the spinal erectors holding your back flat and the adductors (inner thighs) stabilising the hip. Because most of the weight sits on one leg, the working glute and hamstring can't hide behind the stronger side, which makes it a good fix for left-right imbalances.
For muscle and strength, 3 to 4 sets of 8 to 12 reps per leg, twice a week, resting 60 to 90 seconds. Keep the reps slow and controlled rather than heavy and rushed. Always train your weaker side first and match the stronger side to it, so the gap between your legs actually closes.
Either works. A weight in each hand keeps you square and is easiest while you learn. Holding a single dumbbell or kettlebell in the hand opposite your working leg adds an anti-rotation challenge for your core and glute. A kettlebell handle is comfortable to grip through long sets, which is handy for the higher reps this exercise suits.
