Single-Leg Romanian Deadlift — Ipsilateral Load: A Complete Guide
Quick Intro
Single-Leg Romanian Deadlift — Ipsilateral Load is a Balance & Stability exercise performed by standing on one leg while holding a dumbbell in the hand on the same side as the standing leg, then hinging forward at the hip as the free leg rises behind the body to form a straight line with the torso. It builds on Single Leg Romanian Deadlift by moving the load to the same side as the standing leg, pulling the centre of mass toward the stance side rather than away from it.
Equipment Needed
A single Dumbbell is required, loaded lighter than the opposite-side version, since the same-side load pulls the centre of mass in a direction the hip has to resist in a different way.
Why Single-Leg Romanian Deadlift — Ipsilateral Load Matters
Balance is what this exercise trains most, reflecting how much the standing hip has to manage once the load sits directly over the stance side. Coordination comes with it, since the hinge, the rising back leg and the hanging weight all have to move together while the shoulders stay level.
When to Do It
This exercise fits well as an advanced single-leg hinge movement in a general strength or balance session, once Single Leg Romanian Deadlift feels fully controlled on both sides. It isn’t a sensible way to first learn the loaded single-leg hinge pattern.
Anyone newer to loaded single-leg hinge work should master the opposite-side version through a full set before switching the load to the same side. A same-side load removes the natural counterbalance the opposite-side version provides and asks the hip to stabilize against the pull in a considerably less forgiving way.
Getting Ready
Confirm Single Leg Romanian Deadlift feels solid on both sides before switching the dumbbell to the same side as the standing leg. Rehearsing the hinge with a very light load held on the stance side first, checking that the shoulders stay level, is a sensible way to introduce the change.
Step-by-Step Instructions
Entry. Balance on one leg with the dumbbell held in the hand on the same side as the standing leg, keeping the standing knee soft.
Hinge. Fold forward at the hip, letting the dumbbell travel toward the floor while the free leg lifts behind the body until it lines up with the torso. Fight to keep the shoulders level even though the load is pulling directly over the stance side.
Return. Return to standing by squeezing the stance-side glute (gluteus maximus), then repeat for the set before switching sides.
How Many, How Often
Single-Leg Romanian Deadlift — Ipsilateral Load is dosed by reps per side.
| Level | Reps (per side) | Notes |
|---|---|---|
| Beginner | 4-6 reps | Lighter load than the opposite-side version, shoulders checked level |
| Intermediate | 6-8 reps | Moderate load, controlled tempo throughout |
| Advanced | 8-10 reps | Heavier load, minimal visible lateral lean |
Two sets per side is a reasonable dose here, since the lateral stabilization demand through the hip tires considerably faster than the hamstrings do at this load.
Modifications and Variations
This exercise has one easier step, which moves the dumbbell to the opposite hand.
Easier: Single Leg Romanian Deadlift. The identical hinge pattern, with the dumbbell held in the hand opposite the standing leg. This is the appropriate regression for anyone whose shoulders tilt noticeably once the load moves to the same side.
Loading the same side as the standing leg already strips away the natural counterbalance a hinge can offer, so a further step up would mean a heavier load, not a different load placement.
Common Mistakes to Avoid
A common fault in this exercise is letting the shoulders tilt down toward the loaded side as the dumbbell pulls directly over the stance leg. Keeping the shoulders level is the central challenge this load placement is designed to create, and any tilt undoes most of that training value.
A second common mistake is using a load so light that the lateral stabilization demand barely registers. A moderate load that challenges the hip’s ability to resist the same-side pull is what makes this variation meaningfully different from the opposite-side version.
A third mistake is rushing the hinge before the standing leg has found a stable base, the same setup issue that shows up in the opposite-side version, only more pronounced here since there’s no counterbalancing pull to help settle the position first.
After Your Set
A few slow bodyweight calf raises on the working leg, rising onto the toes and lowering under control, gives the ankle and calf an active reset after the sustained hinge. Standing tall and taking a few deep breaths with both feet planted evenly is a simple way to let the hips settle back to level before switching sides.
Going Deeper
This exercise works well as a test of lateral hip stability under load, since moving the dumbbell to the same side removes the natural counterbalance a hinge normally gets from an opposite-side weight. A same-side load already asks about as much lateral control as a standing hinge can reasonably demand without changing the base or the load itself.
Progress here typically comes down to how level the shoulders stay through the bottom of the hinge, not how much weight gets lifted. A heavier load lifted with a visible lateral lean reflects less progress than a lighter load lifted with the shoulders staying level throughout.
How to Know You’re Improving
- Complete 6 to 8 reps per side with the shoulders staying level through the full range of the hinge.
- Notice the standing hip settling into a stable base before the hinge begins, without needing a moment to catch balance mid-rep.
- Reach 8 to 10 reps per side with a load close to what feels manageable on the opposite-side version.
- Keep the free leg and torso forming one straight line at the bottom of every rep, matching the same standard the opposite-side version holds to.
- Treat a level, well-controlled hinge under same-side load as the marker of mastery.
Muscles Worked
- Biceps Femoris (the outer hamstring at the back of the thigh, lengthening and then pulling the torso back upright)
- Gluteus Maximus (the largest glute muscle, extending the hip to finish the lift)
- Gluteus Medius (a smaller glute muscle at the side of the hip, keeping the pelvis level against a load pulling down the same side)
- Erector Spinae (the lower back muscles, bracing the spine against the load’s downward pull)
- Quadratus Lumborum (a deep muscle of the lower back, resisting the sideways pull of the load over the stance leg)
- Tibialis Anterior (a muscle along the front of the shin, correcting at the ankle under the same-side load)
FAQ
Do I need to master the opposite-side version first? Yes. Single Leg Romanian Deadlift should feel solid on both sides before switching the load to the same side, since a same-side load removes the natural counterbalance the opposite-side version provides (see Getting Ready above).
Why does loading the same side as the standing leg feel so different? Because the dumbbell now pulls the centre of mass toward the stance side instead of away from it, asking the hip to resist a pull in a direction it never has to manage when the load hangs on the opposite side.
Should I use the same weight as the opposite-side version? No. Loading lighter at first lets the shoulders stay level while the hip adapts to the new pull direction. Adding weight back gradually once the level-shoulder position feels secure is the safer path (see Common Mistakes to Avoid above).
Is there anything harder than this to move on to? Only by adding load. The hinge’s natural counterbalance is already gone, so any further challenge would come from a heavier dumbbell, not a different load placement.
How many reps should I aim for per side? Six to eight controlled reps per side is a reasonable working range once the opposite-side version feels easy. A smaller number of reps with level shoulders is worth more than a longer set spent leaning through fatigue.
