Dumbbell Lunges
The dumbbell lunge is a single-leg exercise where you step forward or backward into a split position while holding a dumbbell in each hand. It trains the quadriceps and glutes of the front leg, and the offset load makes it a straightforward way to add resistance to a bodyweight lunge.
Also known as: Dumbbell forward lunge, Weighted lunges, Dumbbell walking lunge

What muscles does the dumbbell lunges work?
Primary movers
- Quadriceps
- Gluteus maximus
Assisting muscles
- Hamstrings
- Adductor magnus
- Gluteus medius
- Calves
The front leg does the majority of the work. Its quadriceps extend the knee and its gluteus maximus extends the hip to drive you back up. The back leg contributes far less than most people assume, mostly balance and control of the descent.
Step length changes which muscle dominates. A longer step increases hip flexion and loads the glutes and hamstrings; a shorter step increases knee flexion and biases the quads. Neither is wrong, but it should be a deliberate choice rather than an accident.
The gluteus medius works hard throughout to stop the pelvis dropping on the unsupported side. Single-leg work is one of the few ways to train it meaningfully under load, which is part of why lunges carry over well to running and field sports.
Holding dumbbells rather than a barbell keeps the load below the centre of mass, which makes balance considerably easier and removes any spinal compression from a bar on the back. The trade is grip: at heavy loads your hands often limit the set.
The adductors of the front leg are more involved than in a squat, controlling the thigh against the narrow base of a split stance. This is why lunges frequently produce adductor soreness in people new to them.
How to do the dumbbell lunges
Setup
- 1
Hold a dumbbell in each hand at your sides with your arms straight.
- 2
Stand tall with your feet hip-width apart and your shoulders pulled back.
- 3
Brace your abs and keep your ribs down.
- 4
Pick a fixed point ahead of you to look at. Balance is easier with a steady gaze.
- 5
Decide before the set whether you are stepping forward, backward or walking.
Execution
- 1
Step forward far enough that both knees can reach roughly 90 degrees.
- 2
Lower until your back knee is just above the floor, keeping your torso upright.
- 3
Keep your front shin close to vertical and your front knee tracking over your foot.
- 4
Drive back up through the front heel, not by pushing off the back toe.
- 5
Return to standing under control and reset before the next rep.
- 6
Keep the dumbbells hanging straight down rather than swinging them for momentum.
Common dumbbell lunges mistakes
Stepping too short
A short step drives the front knee far past the toes and puts nearly all the load through the knee joint, which is the usual cause of knee discomfort in lunges.
The fix: Lengthen the step until your front shin is roughly vertical at the bottom. You should be able to see your toes in front of your knee.
Pushing off the back foot
Driving up with the back leg, which reduces the work done by the front leg and defeats the purpose of a single-leg exercise.
The fix: Think about pressing the front heel through the floor. The back foot is there for balance, nothing more.
Leaning the torso forward
Folding at the hips as you descend, usually a sign the dumbbells are too heavy or the core is not braced. It turns the lunge into an awkward hinge.
The fix: Keep your chest tall and your ribs down throughout. If you cannot, reduce the load.
Letting the front knee cave inward
The knee tracking inside the foot on the way up, generally from a weak gluteus medius or from rushing the rep.
The fix: Slow down and actively push the front knee out over your second toe. Reverse lunges are easier to control if forward lunges keep collapsing.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Hypertrophy | 3–4 | 8–12 per leg | Moderate, 1–2 RIR | 90 s |
| Conditioning | 3 | 20–30 total steps | Light, walking lunges | 60–90 s |
| Imbalance correction | 3 | 10–12 per leg | Moderate, weaker side first | 60 s |
Lunges are accessory work rather than a main lift, and they are best placed after your squats or hinges for three to four sets of 8–12 per leg. Reverse lunges are easier on the knees and easier to control than forward lunges, so they are the better default for most people. Be aware that lunges produce more muscle soreness than almost any other leg exercise, particularly walking lunges, so introduce them gradually rather than doing thirty per leg in your first session.

Bodyweight Lunges
EasierThe same pattern unloaded. The right place to build the movement and the balance before adding dumbbells.
Barbell Lunges
HarderA bar on the back removes the grip limitation and raises the load ceiling, at the cost of much harder balance.
Dumbbell Reverse Lunge
EasierStepping backward rather than forward is easier to control and noticeably kinder to the knees.
Dumbbell Walking Lunge
HarderContinuous stepping removes any rest between reps and adds a significant balance and conditioning demand.
Elevating the back foot puts almost all the load on the front leg and removes the stepping entirely.
Frequently asked questions
Are forward or reverse lunges better?
Reverse lunges for most people. Stepping backward keeps the front shin more vertical, which reduces stress on the knee, and it is easier to control the descent. Forward lunges involve more deceleration and carry over better to sport, but they are harder on the knees and harder to do well.
How heavy should dumbbell lunges be?
Heavy enough that 8–12 reps per leg is challenging while your torso stays upright and your balance holds. Grip usually becomes the limit before the legs do, at which point straps or a barbell version are the way forward.
Why do my knees hurt during lunges?
Most often the step is too short, which drives the front knee far past the toes and concentrates load at the joint. Lengthen the step so the front shin is roughly vertical at the bottom, and try reverse lunges, which are consistently easier on the knees than forward ones.
Do lunges build glutes or quads?
Both, and step length decides the balance. A long step increases hip flexion and loads the glutes and hamstrings more; a short step increases knee flexion and biases the quads. Choose your step length based on which you are training rather than letting it happen by accident.
How many lunges should I do?
Three to four sets of 8–12 per leg is plenty as accessory work after your main leg lifts. Start at the lower end, because lunges cause more soreness than most leg exercises, especially in the first few sessions and especially with walking lunges.
Hercules tracks every dumbbell lunges you log, shows you last session's numbers before you lift, and flags when your progress stalls.
