Dumbbell Lunges
Dumbbell lunges have you hold a dumbbell in each hand and step forward, drop your back knee toward the floor, then push back up, alternating legs or completing all reps on one side before switching. They build the quads, glutes, hamstrings, and calves while also training each leg to work independently, which exposes and helps correct strength differences between your left and right side that a squat can hide.
Why it works
A squat lets your stronger leg pick up slack for the weaker one without you ever noticing, since both feet share the load at the same time. A lunge removes that option entirely: each leg has to lower and lift your entire body weight plus the dumbbells on its own, one side at a time. That single-leg demand also asks your hip and ankle stabilizers to work harder than they do in a bilateral lift, since there's only one foot on the ground to manage your balance through the full range of motion.
Set up
- Stand tall holding a dumbbell in each hand at your sides, feet roughly hip-width apart.
- Brace your core and keep your chest lifted before taking the first step.
- Pick a step length long enough that your front knee stays roughly above your ankle at the bottom, not pushed far past your toes.
How to do it
- Step forward with one leg, landing with control rather than a stomp.
- Lower your body by bending both knees until your back knee lightly taps or hovers just above the floor.
- Keep your front shin close to vertical and your torso upright through the descent.
- Push through your front foot to drive back up to the starting standing position.
- Either step the front foot back to standing before switching legs, or continue walking forward, alternating legs with each step.
- Keep the dumbbells hanging naturally at your sides throughout, without swinging them for momentum.
Form cues
- Front knee tracks over your ankle, not past your toes.
- Keep your torso tall, not leaning forward.
- Lower straight down, don't lunge diagonally.
- Drive up through the front heel.
Breathing: Inhale as you lower into the lunge, exhale as you push back up to standing.
Common mistakes
Taking a step so short that the front knee travels well past the toes at the bottom.
Fix: Lengthen your step until your shin stays close to vertical when your back knee reaches the floor.
Leaning the torso forward over the front leg, shifting the work toward the quad and off the glutes.
Fix: Keep your chest lifted and your ribcage stacked over your hips through the entire rep.
Letting the front knee cave inward toward the midline as you push back up.
Fix: Press your front knee out slightly, in line with your second toe, especially on the way up.
Rushing the descent and landing hard on the back knee.
Fix: Lower under control over about two seconds, so your back knee taps the floor lightly instead of dropping into it.
How to program it
- This is a loaded, single-leg compound lift, and each leg is doing the full work of carrying your body weight plus the dumbbells, so treat it like a heavy squat variation rather than something to repeat at full intensity every other day.
- 3 sets of 8 to 12 reps per leg is a solid range once your balance and knee tracking feel automatic.
- If you're already squatting or deadlifting heavy that week, dumbbell lunges make more sense as your one lower-body accessory move than as a second heavy leg day.
- New lifters should spend the first couple of weeks with bodyweight or very light dumbbells, since the balance demand is often the limiting factor before strength is.
Safety notes
- Choose a surface with good footing and enough space in front of and behind you to step without obstruction.
- If your front knee, not your muscles, is what's limiting how deep you go, shorten the range of motion rather than pushing through joint discomfort.

Frequently asked questions
How many sets of dumbbell lunges should I do?
3 sets of 8 to 12 reps per leg works well for most people. Since each leg does the full work of the movement, that's a substantial amount of total leg volume even though the rep count looks modest.
What can I do instead of dumbbell lunges if I don't have space to step?
A split squat with dumbbells trains the same single-leg quad-and-glute pattern from a fixed stance, so you never need to travel forward or back.
Dumbbell lunges vs squats: which is better for building leg strength?
Squats let you load both legs together and generally lift more total weight, which is efficient for raw strength. Lunges train each leg on its own and do more to correct side-to-side imbalances. Most well-rounded leg programs use both.
Why do my knees hurt during dumbbell lunges?
A short step that pushes your front knee well past your toes is the most common cause. Lengthen your stride so your shin stays close to vertical at the bottom of the movement, and shorten the range of motion if discomfort continues.
How deep should I go on a dumbbell lunge?
Lower until your back knee lightly taps or hovers just above the floor. Going deeper than that adds little benefit and puts more strain on the front knee for most people.
