Single Leg Deadlift: Proper Form, Tips & Progressions

The single leg deadlift is humbling. That's the first thing you should know. You might be able to Romanian deadlift heavy dumbbells without thinking twice. But the moment you pick one foot off the floor, everything changes. Your balance disappears, your hip drops, your back rounds, and you're wondering how standing on one leg got so hard.

That struggle is the point. A 2009 study in the Journal of Orthopaedic & Sports Physical Therapy found that single-leg hip-dominant exercises produced significantly higher gluteus medius activation than bilateral variations (Distefano et al., 2009). The gluteus medius is your primary hip stabilizer. When it's weak, your knees cave, your hips shift, and your lower back picks up the slack. Single leg deadlifts fix that.

But here's the honest truth: this exercise has a steep learning curve. Most people need 2-3 weeks of practice before their balance catches up to their strength. So this guide covers the progression from bodyweight to loaded, the form details that make or break the movement, and why you should start way lighter than your ego wants.

Quick Facts

How to Do a Single Leg Deadlift (Step-by-Step)

1. Set up your stance. Stand tall on your right leg with a slight bend in the knee. Hold a dumbbell in your left hand (opposite hand from standing leg). Let your left foot hover just behind you, barely off the floor. Plant your standing foot firmly. Weight should be spread across the whole foot, not just your toes.
2. Hinge at the hip. Push your hips straight back. Your torso lowers toward the floor as your free leg extends behind you as a counterbalance. Think about your body as a seesaw with the pivot at your hip joint. As your chest goes down, your back leg goes up. Keep your back flat and your core braced the entire time.
3. Lower to your range. Keep hinging until your torso and back leg are roughly parallel to the floor, or until you feel a strong stretch in your standing hamstring. The dumbbell hangs directly below your shoulder. Don't round your back to get lower. Your range of motion is wherever your hamstrings say "that's enough." Respect it.
4. Drive back up. Squeeze your glute hard and push the floor away with your standing foot to reverse the hinge. Don't jerk up. Control the ascent just like you controlled the descent. Return to tall standing with your back leg coming underneath you. That's one rep.
5. Finish one side, then switch. Complete all reps on one leg before switching. Typical range is 8-12 reps per side. Start with your weaker side (for most people, the left) so you match the same reps and weight on both legs. No favorites.

Coach Ty's Tips: Single Leg Deadlift

These are the cues Coach Ty gives when he's watching your single leg deadlifts in the app. This exercise has more failure points than most, so Ty's real-time feedback is particularly useful here:

• Fix your gaze. Pick a spot on the floor about 6 feet in front of you and don't take your eyes off it. Your balance system relies heavily on visual input. The moment you start looking around or glancing in a mirror, your balance collapses. One spot. Locked eyes. The entire set.
• Slow down. Honestly, speed is the number one reason people can't do this exercise. Take a full 3 seconds to lower and 2 seconds to come back up. The slower you go, the more your stabilizers engage, and the faster your balance improves. Rushing through reps teaches your body nothing except how to wobble.
• Use the contralateral hand. Dumbbell goes in the hand opposite to your standing leg. Right leg standing, left hand holds the weight. This creates a natural cross-body load that your core has to resist, which is actually how your body works when you walk and run. Same-side loading works too, but it's less functional and less core demand.
• Think "hip back," not "lean forward." The biggest mental cue that changes everything. You're not bending forward at the waist. You're pushing your hips backward. The forward lean of your torso is a consequence of the hip hinge, not the goal. If you think "lean forward," your back rounds. If you think "hip back," your back stays flat.

Common Mistakes to Avoid

This is an expert-level exercise for a reason. The balance demand alone filters out most beginners. But even experienced lifters make these mistakes regularly.

• Hip rotation. Your hips should stay square to the floor throughout the entire movement. When your free leg goes back, the hip on that side wants to open up toward the ceiling. Fight it. Think about keeping both hip bones pointing straight down at the floor. If your hips rotate, your lower back takes the rotational force, and that's a recipe for problems.
• Rounding the back. Just like the bilateral Romanian deadlift, a rounded back under load is a no-go. The fix is the same: stop lowering when your back starts to round. That's your current range of motion. It'll improve over time. Forcing depth at the expense of spinal position is never worth it.
• Going too heavy too soon. Your ego will tell you to grab the same dumbbells you use for regular deadlifts. Don't listen. Start at about 30-40% of your bilateral weight. So if you RDL with 40-pound dumbbells, start single leg with one 15-pound dumbbell. Build up only when your balance can handle it. The strength is there. The stability isn't. Not yet.
• Rushing through the set. Look, I get it. Wobbling around on one leg feels awkward, and the natural impulse is to speed up and get it over with. But fast reps on a single leg deadlift are just controlled falling. Slow the tempo down. 3 seconds down, pause, 2 seconds up. If you can't do that with control, the weight is too heavy or you need more time with the bodyweight version.

Variations: From Beginner to Advanced

Kickstand Deadlift (Beginner)

Instead of lifting your back foot completely off the ground, keep the toes of your back foot lightly touching the floor behind you. This gives you a balance assist while still loading the front leg for 80-90% of the work. If the full single leg version has you tipping over every rep, start here. It's not cheating. It's a progression. When you can do 3 sets of 10 with a dumbbell and zero wobble, you're ready to lift that back foot.

Bodyweight Single Leg Deadlift (Intermediate)

Same movement, no dumbbell. Extend your arms in front of you or out to the sides for balance. This is where you build the proprioception and hip stability before adding load. Honestly, most people should spend at least 2-3 weeks here before picking up a weight. It's going to feel frustratingly easy from a strength perspective and frustratingly hard from a balance one. That's normal.

Barbell Single Leg Romanian Deadlift (Expert)

Hold a barbell with both hands instead of a single dumbbell. This significantly increases the load but actually helps with balance since the weight is distributed symmetrically. Only attempt this if you've mastered the dumbbell version with solid form. And use bumper plates so you can safely bail if you lose your balance.

Alternative Exercises

If single leg deadlifts aren't working for you yet, these build the same muscles:

• Romanian deadlift: The bilateral version. Same hip hinge, same muscles, no balance demand. Master this first if you're new to hinging.
• Glute bridge: If hinging is too advanced right now, glute bridges train the hamstrings and glutes from a lying position with zero balance requirement. Try the single leg version for unilateral work.

Programming Tips

Here's where single leg deadlifts fit in your training:

• Beginners: 3 sets of 8 reps per side, bodyweight or kickstand with light dumbbell. Focus on balance and flat back position. Place after your main bilateral lifts (squats, deadlifts) while you have energy for the balance demand.
• Intermediate: 3 sets of 10-12 reps per side with a moderate dumbbell (15-25 lbs). Use a 3-second lowering tempo. Pair with a quad exercise for balanced leg development.
• Advanced: 3-4 sets of 8-10 reps per side with a heavy dumbbell or barbell. Can serve as your primary hip hinge movement on unilateral training days. Superset with a core exercise for efficiency.
• Frequency: 2-3 times per week with 48-72 hours between sessions. Your hamstrings and glutes need recovery time, especially when loaded. And your nervous system needs recovery from the balance demand, which people underestimate.

FitCraft's AI coach Ty programs single leg deadlifts into your personalized plan based on your assessment results and available equipment. Ty's 3D demonstrations show the hip hinge from multiple angles (the side view is particularly useful for checking your back position), and the app tracks left-right performance differences so you can address imbalances before they become problems.
