The single-leg Romanian deadlift is a hip hinge done on one leg. It trains the hamstrings and glutes of the standing leg and makes your hip and foot work to hold your balance.
Left: start position. Right: end position. Orange: the muscles that work.
Breathing. Breathe in and brace at the top. Hold the brace while you hinge down, and breathe out as you drive your hip forward and stand up.
The single-leg rdl works mainly the hamstrings and glutes.
| Muscle | Role |
|---|---|
| Hamstrings | Main mover. They lengthen under load as you hinge down and pull the hip back to standing on the way up. |
| Glutes | Extend the hip with the hamstrings. The smaller glute muscles on the side of the standing hip also keep your pelvis level so that it does not drop or twist. |
| Lower back (also works) | Holds your spine in a neutral position while your torso leans forward. It works to keep the back still, not to bend it. |
| Abs (core) (also works) | Resists the twist that comes from standing on one leg with the other leg reaching back. |
| Goal | Sets | Reps | Rest |
|---|---|---|---|
| Beginner (first weeks) | 3 | 10-20 reps | 75 s |
| Build muscle | 3 | 8-20 reps | 90 s |
| Get stronger | 3 | 6-20 reps | 2 min |
| General fitness | 3 | 10-20 reps | 75 s |
| Fat loss (with more daily activity) | 3 | 12-20 reps | 60 s |
These numbers come from the same rules as the Oh My Coach app. Use a load that leaves 1 to 3 reps in reserve. When you reach the top of the range in every set, add a little load or move to the harder version (double progression). What is double progression?
Why it matters: The free leg turns out and the pelvis rotates, so the hamstring stretch gets smaller and you lose balance.
Fix: Point the toes of the free foot at the floor and keep both hip bones facing down.
Why it matters: The motion moves from the hip to the spine, and the hamstrings get less stretch.
Fix: Go only as low as you can with a flat back. Range comes from the hip, not from the hands reaching the floor.
Why it matters: The movement turns into a one-leg squat, so the quads take over and the hamstrings do less.
Fix: Set a slight knee bend at the start and keep that angle for the whole rep.
Why it matters: A fast hinge on one leg makes you wobble, and you stop the set because of balance, not because the muscles are tired.
Fix: Move slowly on the way down and pause for a moment at the bottom.
If you cannot do clean reps yet, start with the bodyweight good morning.

No equipment You can do this exercise anywhere.
This exercise loads the hip and ankle. If your hip hurts, stop. Options that do not load the hip in the same way: Barbell deadlift, Trap-bar deadlift. For pain that does not go away, see a doctor or a physiotherapist.
If your hip or ankle hurts, stop the set. Try the bodyweight good morning on two feet instead.
It works mainly the hamstrings and glutes of the standing leg. The lower back holds your spine still, and the abs and the small hip muscles keep you from twisting or tipping over.
They do different jobs. The two-leg version lets you use much more load. The one-leg version needs less weight, adds a balance demand and trains each side on its own. The ACSM position stand recommends both one-leg and two-leg exercises in a strength program.
In the app, the bodyweight good morning is the easier step. You can also keep the toes of the back foot on the floor as a kickstand, or hold a wall with one hand.
A deadlift starts from the floor with more knee bend, so the quads help more. In an EMG study of the two-leg lifts, the conventional deadlift used the front of the thigh much more than the Romanian deadlift.
