Stiff Leg Deadlift Aka Romanian Deadlift Overview
The stiff leg deadlift aka romanian deadlift builds your hamstrings. The hamstrings are the muscles on the back of your thighs. You hold a barbell and hinge at your hips. You push your butt back and lower the bar down your legs. It also works your glutes and back. Your glutes are your butt muscles. You need a barbell. This is an intermediate move. It teaches the hip hinge, a key pattern for life and sport. It builds strong hamstrings and glutes. It also makes your whole back line stronger. Keep your knees only slightly bent the whole time. Add it to a leg or pull day. Start light and learn the hinge first.
What Is The Point of the Stiff Leg Deadlift Aka Romanian Deadlift?
The stiff leg deadlift aka romanian deadlift builds stronger hamstrings and glutes while teaching proper hip hinge movement. It's one of the best moves for your posterior chain.
How To Do The Stiff Leg Deadlift Aka Romanian Deadlift
- Set up standing tall holding a barbell with both hands in front of your thighs, using a shoulder-width overhand grip. Your feet should be about hip-width apart with a slight bend in your knees.
- Set your shoulders down and back and pull the bar in tight against your legs. Brace your core by taking a big breath into your belly, as if you are about to be punched in the stomach.
- Keep that slight knee bend fixed for the whole movement. Unlike a squat, the knees stay mostly still here, since the power comes from your hips hinging.
- Begin the descent by pushing your hips straight back, letting your torso tip forward as a unit. Think about reaching your glutes toward the wall behind you rather than bending down.
- Slide the bar down your thighs and shins, keeping it in contact with your legs the entire way. A bar that drifts away from you loads your lower back and kills your leverage.
- Lower until you feel a strong stretch in your hamstrings, usually around mid-shin or just below the knee depending on your flexibility. Keep your back flat and never round it to go lower.
- Stop when your hamstrings are fully stretched or your back is about to round, whichever comes first. This is the bottom, and the stretch is the whole point.
- Drive your hips forward to stand back up, squeezing your glutes hard at the top and pulling the bar back into your body. Do not overextend or lean back at the top.
- Keep the bar close and your spine neutral throughout, and repeat for your reps. The Romanian deadlift works well in the 6 to 12 rep range for building the hamstrings and glutes.
Stiff Leg Deadlift Aka Romanian Deadlift Form Tips
- Keep your back flat the whole time. Never let it round.
- Push your hips back, not down. This is a hinge, not a squat.
- Keep the bar close to your legs. Let it slide down your thighs.
- Keep your knees slightly bent and still. Do not bend them more.
- Lower until you feel your hamstrings stretch. Do not force lower.
- Squeeze your glutes at the top. Do not lean back.
- Move slow and controlled. No bouncing at the bottom.
- Breathe in at the top, brace, then hinge. Breathe out as you stand.
- Keep your shoulders pulled back. Do not let them slump forward.
Common Mistakes to Avoid for the Stiff Leg Deadlift Aka Romanian Deadlift
- Rounding the lower back to reach lower. Chasing extra range by letting the spine round puts your discs under serious load and is the fastest way to hurt yourself here. Only go as low as you can keep a flat back, and let your hamstring flexibility set your depth.
- Turning it into a squat. Bending the knees a lot and dropping your hips down shifts the work to the quads and defeats the purpose of a hip hinge. Keep the knee angle fixed and push your hips straight back so the hamstrings and glutes do the work.
- Letting the bar drift away from your legs. A bar that swings out in front dramatically increases the load on your lower back and wrecks your leverage. Keep the bar shaved against your thighs and shins the entire rep.
- Not pushing the hips back. Trying to bend straight down instead of hinging at the hips loads the spine instead of the hamstrings. Initiate every rep by driving your glutes back toward the wall behind you.
- Going too heavy too soon. Ego loading forces your back to round and turns a clean hinge into a dangerous grind. Pick a weight you can control with a flat back through a full stretch, then add load slowly over time.
- Failing to brace the core. A loose trunk lets your spine move under load, which is exactly what you want to avoid on a hinge. Take a big breath, brace hard, and keep that tension from the top of the rep to the bottom.
- Hyperextending at the top. Leaning back and cranking your hips past straight at lockout stresses the lower back for no benefit. Finish standing tall with glutes squeezed and ribs down, in a neutral, stacked position.
- Rushing the eccentric. Dropping into the stretch quickly wastes the lowering phase, which is where the hamstrings get loaded hardest. Lower under control for two to three seconds and feel the stretch build.
- Overbending or locking the knees fully. Straight, locked knees put all the strain on your back and hamstring tendons, while too much bend turns it into a squat. Hold a soft, fixed knee bend the whole time.
- Looking straight up or tucking the chin hard. Cranking the neck to look up breaks your neutral spine at the top end. Keep your gaze a few feet in front of you so your neck stays in line with your back.
- Bouncing at the bottom. Using a bounce out of the stretch to rebound the weight up robs the hamstrings and risks your back. Reach the stretched position under control, then drive the hips forward smoothly.
Stiff Leg Deadlift Aka Romanian Deadlift Workout Tips
- Master the hip hinge before you load it heavy. The whole exercise is pushing your hips back with a flat back and a fixed knee bend, so groove that pattern with light weight first.
- Keep the bar glued to your legs. A bar path that hugs your thighs and shins keeps the load over your hips and protects your lower back from unnecessary strain.
- Let hamstring flexibility set your depth. Lower only as far as you can keep a flat back and feel a strong stretch, since going deeper by rounding just risks injury.
- Control the eccentric for two to three seconds. The lowering phase is where the hamstrings are loaded hardest, so resisting on the way down drives a lot of the growth.
- Squeeze your glutes hard at the top. A firm glute contraction finishes the hip extension and teaches you to lock out with your hips rather than your lower back.
- Brace your core like a punch is coming. A hard brace keeps your spine neutral and stable under load, which is the key to hinging safely.
- Train it in the 6 to 12 rep range. This range builds the hamstrings and glutes well while keeping the reps controlled enough to protect your back.
- Program it as a main posterior-chain builder. The RDL is one of the best hamstring and glute movements, so give it a prominent spot on leg or pull days.
- Feel the stretch as your guide, not the floor. This is not about touching the plates to the ground, it is about loading the hamstrings through their stretch.
- Add it to bulletproof your deadlift and sprint speed. Strong hamstrings and glutes carry directly over to a bigger conventional deadlift and more powerful athletic movement.
- Try a slow tempo or a pause in the stretch. Emphasizing the stretched position under control builds serious hamstring strength and size.
- Use straps if grip is your limiting factor. When your hamstrings can handle more than your hands, straps let you keep loading the target muscles without your grip failing first.
- Keep your neck neutral. Looking a few feet ahead keeps your whole spine in line and avoids cranking your neck at the top of the lift.
- Film from the side to check your hinge. Video quickly reveals a rounding back or a bar drifting forward, which are hard to feel in the moment.
- Progress with small, steady load increases. The posterior chain is strong and responds well to patient progressive overload over months.
- Do not chase failure with sloppy form. Stop the set when your back is about to round, because a clean hinge is always worth more than one extra ugly rep.
