Dumbbell Lunge
The dumbbell lunge is a single-leg exercise in which, holding a dumbbell in each hand, you step forward into a long stride, sink until both knees are bent to about 90°, then push back to standing. It works the front leg's quadriceps and glutes, with the hip muscles controlling balance as you step, and it is one of the most common loaded single-leg exercises.
Also called: DB Lunge, DB Forward Lunge, Dumbbell Front Lunge, Hand-Held Forward Lunge · Equipment: dumbbell · Pattern: squat
Step by step
- Stand tall with your feet hip-width apart, holding a dumbbell in each hand at your sides with palms facing in.
- Brace your trunk, then take a long step forward with one leg, keeping the feet hip-width apart as if on two rails.
- Plant the whole front foot and let the back heel lift so you are on the ball of the back foot.
- Sink straight down until both knees are at about 90° and the back knee is just above the floor. Keep the front knee tracking over the middle toes and the front heel down.
- Drive through the whole front foot to push yourself back up and return the front foot beside the other.
- Stand fully tall, re-brace, then step with the same leg or alternate legs.
- Keep the dumbbells hanging straight at your sides for every rep, and finish the same number of reps on each leg.
- Long step, sink straight down
- Push the floor away through the whole front foot
- Front knee over the middle toes
- Chest tall, dumbbells hanging still
- Feet on two rails, hip-width apart

What goes wrong, and the fix
Step too short
Fix: Step long enough that both knees reach about 90° at the bottom, front heel down.
Feet on one line
Fix: Step forward on your own rail, keeping the feet hip-width apart.
Front knee caving inward
Fix: Keep the front knee tracking over the middle toes for the whole rep.
Falling into the step
Fix: Plant the front foot, then sink under control rather than dropping.
Cutting depth short
Fix: Sink until the back knee is just above the floor on every rep.
Small push-backs off the front foot
Fix: Drive hard through the whole front foot and bring it all the way back to stand.
What the research says
Muscle growth · first choiceGeneral fitness · first choiceFat loss & conditioning · first choiceStrengthRehab & prehabSport performanceEndurance
- 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. Neither showed a clear edge for sprinting or change of direction.
- Load by goal — Research comparing loads finds maximal strength favours heavier loads, while muscle growth is similar across a wide range of loads when sets are taken close to failure. Many lifters find grip limits heavy dumbbell lunges before the legs do.
- Torso angle — A lab study found a slight forward lean in the lunge raised glute and hamstring muscle activity compared with an upright torso. That is a measure of activity, not of growth.
- Effort — Studies show sets that finish a few reps short of failure capture most of the growth benefit, and true failure adds only a small extra return.
- Volume and frequency — Research links more weekly sets for a muscle to more growth, with diminishing returns. Around 10 or more hard sets a week has been associated with more growth than fewer than 5, and training a muscle about twice a week is a common way to spread that volume.
