Dumbbell Rear Lunge
The dumbbell rear lunge has you stepping one leg backward into a lunge while a dumbbell hangs in each hand, then driving back up through the front leg. Stepping back rather than forward keeps most of your weight loaded onto the front leg the entire rep, which makes it a quad-focused, single-leg exercise with the glutes and hamstrings pitching in to stabilize the hip. It suits anyone building single-leg strength for running, sports, or general lower-body work, especially if forward lunges have felt harder on the front knee than they should.
Why it works
Because the moving leg steps backward rather than the front leg stepping forward, your front knee stays roughly stacked over your ankle for the whole rep instead of traveling forward the way it can in a walking lunge. That keeps more of the demand on the quadriceps of the front leg through a controlled range, while the glutes and hamstrings work to keep your hip from collapsing sideways as you balance on one leg. Training one leg at a time also exposes and corrects side-to-side strength differences that a bilateral squat can hide, since neither leg gets to help carry the other's share of the load.
Set up
- Stand tall holding a dumbbell in each hand at your sides.
- Find your balance on the front leg before stepping back.
- Keep your torso upright and your core braced before the first rep.
How to do it
- Step one leg straight back, landing on the ball of that foot.
- Lower your body until your front thigh is roughly parallel to the floor and your back knee hovers just above it.
- Keep most of your weight on the front leg rather than letting the back foot bear it.
- Push through the front heel to stand back up, bringing the back leg forward to the starting position.
- Complete all reps on one side before switching legs, or alternate if that suits your program.
Form cues
- Front knee stays stacked over the ankle.
- Most of the weight rides on the front leg.
- Torso stays tall, no leaning forward.
- Push through the front heel to rise.
Breathing: Inhale as you step back and lower, exhale as you drive back up to standing.
Common mistakes
Letting the front knee cave inward as you lower or push back up.
Fix: Actively press the front knee out over your toes during the rep, and lighten the dumbbells if you can't keep it tracking straight.
Leaning the torso forward, which shifts the work off the front leg and onto the lower back.
Fix: Keep your chest up and your torso stacked over your hips throughout the movement, even if that means a shorter step back.
Pushing off the back foot instead of the front heel to stand back up.
Fix: Keep the back foot light, on the ball of the foot only, and drive the standing motion entirely through the front leg.
Rushing the step back and landing hard instead of controlling the descent.
Fix: Slow the step down and lower under control; a controlled rear lunge protects the front knee far better than a fast, bouncy one.
How to program it
- Eight to twelve reps per leg, for two or three sets, builds solid single-leg strength without excessive soreness.
- Because it's unilateral, the load through each leg is lower than a bilateral squat with the same dumbbells, so twice a week on a leg day works well for most people.
- Master the bodyweight version and a comfortable balance point before adding dumbbells, especially if you're newer to single-leg training.
- Pairs well with a hip hinge movement like a Romanian deadlift on the same day, since the two cover different parts of the lower body.
Safety notes
- Keep the front knee tracking over the toes rather than caving inward, which is the most common source of knee discomfort in this exercise.
- Take a shorter step back if you feel any strain in the front knee, and build up the step length gradually as balance improves.

Frequently asked questions
How many sets and reps of dumbbell rear lunges should I do?
Two or three sets of 8 to 12 reps per leg is a solid range for most people. Since it's a single-leg movement, twice a week is usually enough to make steady progress.
Why does my front knee hurt during rear lunges?
It's usually the knee caving inward under load. Focus on pressing the front knee out over your toes throughout the rep, and use lighter dumbbells until that tracking feels automatic.
Rear lunge vs forward lunge, what's the difference?
Stepping backward keeps your front knee more stacked over your ankle, which many people find gentler on the joint. Stepping forward asks the front knee to travel further, which can feel harder to control at first but trains a slightly different range.
Can I do rear lunges without dumbbells?
Yes, a bodyweight rear lunge trains the same pattern and is the right place to start if your balance or front-knee tracking isn't solid yet.
