Single-Leg Romanian Deadlift
Move · Resistance Training · Movement, Typed Supps
Because the weight hangs to one side of the leg you are standing on, the muscles on the outside of that hip end up working as hard as the hamstring behind it.
Stage by stage
- Set-up (Knee angle fixed): A constant slight bend in the standing knee ensures hip flexion produces the range rather than the knee unloading the hamstring.
- During the set (Three planes at once): The offset load creates an adduction and rotation moment the hip has to resist while it is also producing extension.
- At the bottom (Hamstring loaded long): Increasing hip flexion lengthens the external moment arm and loads the hamstrings near long muscle lengths.
- Weeks later (Control before strength): Postural control is the ceiling on load, so early progress is coordination and only later per-limb strength.
Muscles trained
- Primary: hamstrings
- Secondary: abs, glutes, hip abductors, lower back
Intensity
3.5 METs (Resistance (weight) training, multiple exercises, 8-15 repetitions at varied resistance).
Time to effect
- Weeks: Balance and hip stability on the working leg improve fast, since most of the early struggle is coordination rather than strength.
- Months: Hamstring and glute strength even out between the two legs, closing side-to-side imbalances a bilateral deadlift can hide, and single-leg stability translates into better change-of-direction control.

Common myth
"Single-leg RDLs are just a lighter version of the regular RDL." In reality: The load per leg is actually similar to or even higher than a bilateral RDL for the working side, since one leg is doing the job two normally share; what's lighter is the total weight on the bar or in the hand, because balance becomes the limiting factor long before hamstring strength does.
