Dumbbell Single Leg Split Squat
Reviewed by Dylan Maurick, Physiotherapist
The Dumbbell Single Leg Split Squat is a unilateral lower-body exercise that builds leg strength, balance and control using dumbbells.

Muscles Worked: Dumbbell Single Leg Split Squat
The Dumbbell Single Leg Split Squat mainly trains your legs, with your quads driving you up from the bottom and your glutes helping straighten the hip and keep the working leg strong. Your hamstrings support the movement and help steady the knee and hip as you lower and rise. Because you are loading one leg at a time, the glutes also work hard to keep your hips level and stop you from tipping side to side. You should feel the front of the working thigh and the glute doing most of the work, especially since single-leg squat variations show strong lower-limb muscle activation and balance demands (Knoll et al., 2019).
Technique and form
How to perform the Dumbbell Single Leg Split Squat
- Stand in a split stance with your left foot forward and right foot 2-3 feet behind you, holding a dumbbell in each hand at your sides with palms facing inward.
- Keep your torso upright, core engaged, and distribute your weight primarily through your front heel while the back foot is positioned on the ball of your foot.
- Inhale as you begin to lower your body straight down by bending your front knee, keeping it aligned with your toes while your back knee travels toward the floor.
- Allow your back knee to descend until it nearly touches the floor (about 1-2 inches above) while maintaining a tall chest and neutral spine.
- Once you've reached the bottom position, exhale as you drive through your front heel to push back up to the starting position.
- Focus on using the quadriceps, hamstrings, and glutes of your front leg to power the movement while your back leg primarily assists with balance.
- Complete all repetitions on one leg before switching to the other side, maintaining consistent breathing throughout each repetition.
- Keep your shoulders relaxed and gaze forward throughout the exercise to maintain proper posture and prevent unnecessary neck strain.
Important information
- Ensure your front knee tracks in line with your toes and doesn't collapse inward or extend beyond your toes during the movement.
- If balance is challenging, position yourself near a wall or sturdy object for support until your stability improves.
- Start with lighter weights until you master proper form, then gradually increase the load as your strength and stability develop.
- If you experience knee pain, try adjusting your stance width or elevating your back foot on a low platform to reduce stress on the joints.
Is the Dumbbell Single Leg Split Squat good for muscle growth?
Yes. The Dumbbell Single Leg Split Squat is a strong muscle-building exercise for your quads and glutes because one leg does most of the work through a long range of motion, which creates high tension where you want it most. Single-leg squat variations also place meaningful demands on lower-limb muscle activation and balance control, which can increase the training demand on each rep (Knoll et al., 2019).
- High glute demand — Split and single-leg squat patterns make your glutes work hard not just to stand up, but also to help control the pelvis and hip during the movement. That added stability demand is one reason these movements are useful when your goal is to challenge the glutes under load (Collings et al., 2023).
- More work per leg — Since one leg takes most of the load, you can train each side hard without needing the same total weight you would use in a bilateral squat. That makes it easier to build the quads and glutes while keeping the lower back demand lower than many two-leg lifts.
- Longer effective range — The split stance lets you sink deep if your mobility allows, which gives the front leg more knee bend and hip bend. That usually means more work for the quads and glutes than a shorter, shallow rep. If you want a close variation, compare it with the bulgarian-split-squat.
- Easy to progress — You can add reps, slow the lowering phase, pause at the bottom, or increase dumbbell load in small jumps. If balance is the main limiter, the dumbbell-single-leg-squat is usually harder, so this split stance is often the better place to build size first.
Programming for muscle growth
Do 3-5 sets of 6-12 reps per leg with 75-120 seconds rest between sets. Train it 1-2 times per week, placing it early in the workout if leg size or single-leg strength is a priority. Use a load that brings you close to failure with 1-3 reps left in the tank, and keep each rep deep and even so the target muscles do the work instead of rushing through the set.

FAQ - Dumbbell Single Leg Split Squat
This exercise primarily targets the quadriceps, glutes, and hamstrings, while also engaging stabilizer muscles throughout your legs and core. The unilateral nature makes it exceptional for identifying and correcting muscle imbalances between your left and right sides.
Beginners can start without weights or holding onto a stable surface for balance. To increase difficulty, add heavier dumbbells, elevate your rear foot, slow down the eccentric (lowering) phase, or add a pulse at the bottom position.
The most common mistakes include rounding your lower back, rotating your hips instead of keeping them square, rushing through the movement, and not hinging properly at the hips. Focus on maintaining a neutral spine, moving with control, and keeping your standing knee slightly soft rather than locked.
For optimal results, incorporate this exercise 1-2 times weekly with at least 48 hours between sessions to allow for recovery. More advanced lifters can perform it up to 3 times weekly if properly managing overall training volume and intensity.
The single leg split squat can actually benefit those with minor knee issues by strengthening supporting muscles when performed with proper form. Start with bodyweight only and focus on controlled movement, but consult a physical therapist if you have significant knee pain or previous injuries.
