Dumbbell Lateral Lunge
The dumbbell lateral lunge is a side-step lunge: you step wide to one side, sit into that hip with the other leg straight, then push back to the centre while holding a dumbbell. It works the quadriceps and glutes of the bent leg and puts the inner-thigh (adductor) muscles of the straight leg under a loaded stretch, training movement in the side-to-side plane.
Also called: DB Lateral Lunge, Dumbbell Side Lunge, DB Side Lunge, Goblet Lateral Lunge · Equipment: dumbbell · Pattern: squat
Step by step
- Hold one dumbbell vertically against your chest by its top end, or a dumbbell in each hand at your sides. Stand tall with your feet together and toes forward.
- Take a wide step directly to one side, about twice shoulder width, and plant the whole foot with the toes pointing forward or slightly out.
- As the foot lands, push your hips back and bend the stepping knee to sit into that hip. Keep the other leg straight with its foot flat on the floor.
- Sink under control until the bent-leg thigh is close to parallel with the floor, or as deep as you can go with that heel down and your chest tall. You feel a stretch along the inner thigh of the straight leg.
- Keep the bent knee in line with the middle toes and the whole working foot on the floor throughout.
- Drive through the whole working foot to push back to the start and stand tall with your feet together.
- Complete all reps on one side, then switch, or alternate sides on each rep.
- Step wide and sit back into the working hip
- Working knee over the middle toes
- Trailing leg long, foot flat
- Chest tall, dumbbell close to your body
- Push the floor away to come back to the centre

What goes wrong, and the fix
Working knee caving inward
Fix: Keep the working knee in line with the middle toes as you sit into the hip.
Squatting straight down
Fix: Push the hips back as the foot lands, as if sitting onto a chair behind you.
Stepping too narrow
Fix: Step wide enough that the trailing leg is straight with its foot flat at the bottom.
Trailing foot rolling onto its edge
Fix: Keep the whole sole of the trailing foot on the floor, toes pointing forward.
Chest collapsing forward
Fix: Hold the dumbbell close to your chest and keep your chest up as you sit back.
Dropping into the bottom
Fix: Take about two seconds to sit into the bottom, then drive back out.
What the research says
Muscle growthRehab & prehabGeneral fitnessSport performanceEnduranceFat loss & conditioning
- Direction changes the demand — In a biomechanics study of lunge direction, the forward lunge placed 45–65% more demand on the hip extensors, while the lateral lunge loaded the knee and ankle extensors more and bent the ankle further.
- Muscle activity — EMG studies of single-leg lunge and step-up patterns rank the outer and inner quadriceps highest, followed by the gluteus medius and gluteus maximus. This describes activation, not growth.
- Single-leg transfer — A meta-analysis of 14 training studies found single-leg training carried over more to single-leg jumping, and two-leg training more to two-leg strength, with no clear edge either way for change of direction.
- Load and effort — Research finds muscle growth is similar across a wide range of loads when sets finish close to failure. Many lifters use moderate loads of about 8–15 reps per side, because balance tends to limit the set before the legs do.
