Why the Single-Leg Deadlift is the King of Exercises

When it comes to exercises that give you the most return for your effort, few moves compete with the single-leg deadlift. It’s not just a favourite among runners or athletes—it’s a movement with incredible carryover into everyday life. If I had to choose one exercise that builds strength, balance, and resilience all in one, the single-leg deadlift would take the crown.

Builds Balance You Can Use in Real Life

Think about how often you find yourself on one leg during daily life: walking, climbing stairs, picking something up from the floor, even standing to put on your socks. The single-leg deadlift directly trains this balance. By challenging you to hinge at the hips while staying stable, it forces your brain and body to coordinate together. Over time, you build the kind of balance that sticks—not just while exercising, but while moving through the world.

Strengthens the Posterior Chain

Your posterior chain—the muscles along the back of your body like your hamstrings, glutes, and lower back—are the powerhouses behind almost every athletic and everyday movement. The single-leg deadlift lights up this entire chain. It strengthens your glutes (especially the glute medius, the often-neglected lateral hip muscle), builds hamstring resilience, and supports your lower back. A stronger posterior chain means fewer injuries, more power, and better posture.

Works the Lateral Hip Muscles

One of the most overlooked benefits of the single-leg deadlift is how much it challenges your lateral hip muscles. These stabilisers keep your pelvis level and your hips strong, which is key for preventing injuries in the knees and lower back. If you’ve ever struggled with hip or knee pain, this exercise could be the missing piece. Strong lateral hips also make everyday movements like carrying shopping bags, pushing open heavy doors, or walking on uneven ground much easier.

Teaches Control and Coordination

The single-leg deadlift isn’t just about raw strength—it’s about control. You can’t rush through it. To perform it properly, you need to engage your core, stabilise your standing leg, and move with precision. This teaches body awareness and coordination, qualities that carry over into everything from sports performance to daily activities like bending, lifting, or carrying.

Perfect for Runners (and Beyond)

For runners, the single-leg deadlift is gold. Running is essentially a series of single-leg movements, so strengthening your balance, hip stability, and posterior chain directly improves running efficiency and reduces injury risk. But even if you’re not a runner, the benefits are universal. Whether you’re an office worker who wants to avoid back pain, a parent lifting kids, or simply someone who wants to move well as you age, this exercise delivers.

The Bottom Line

The single-leg deadlift isn’t just an exercise—it’s a foundation for better movement. It builds strength where most people are weak, challenges balance and coordination, and prepares your body for both sport and life. If you’re looking for one exercise that does it all, make this your king.

❓ Frequently Asked Questions About the Single-Leg Deadlift

1️⃣ What muscles does the single-leg deadlift work?

It primarily targets the posterior chain—hamstrings, glutes, and lower back—while also engaging the lateral hip muscles, core, and stabilisers in the ankle and foot.

2️⃣ Is the single-leg deadlift good for beginners?

Yes! Beginners can start with bodyweight only, focusing on balance and control before adding weights like dumbbells or kettlebells.

3️⃣ Why is the single-leg deadlift harder than the standard deadlift?

Because you’re working on one leg, you’re not just lifting—you’re balancing, stabilising, and coordinating at the same time. This makes it more challenging but also more effective for overall movement.

4️⃣ Is the single-leg deadlift only for runners?

Not at all. While runners benefit hugely, the exercise helps anyone who wants better balance, stronger hips, and more resilient hamstrings—qualities that carry over into everyday life.

5️⃣ How often should I do single-leg deadlifts?

Two to three times per week is ideal, either as part of your strength training program or integrated into warm-ups and mobility work.
