Dumbbell Split Squat

The dumbbell split squat is a stationary single-leg squat: feet split front and back, both planted, a dumbbell in each hand, you sink straight down and stand back up without moving your feet. It works the front leg's quadriceps and glutes, with the hip muscles steadying the pelvis, and it is the most stable way to load a split stance.

How to do it

Step by step

  1. Hold a dumbbell in each hand at your sides, palms facing in, and stand tall with your feet hip-width apart.
  2. Step one foot back and set it on the ball of the foot. Keep the feet hip-width apart, as if on two rails, and make the stance long enough that both knees reach about 90° at the bottom.
  3. Put most of your weight through the whole front foot. Take a breath, brace your trunk and stand tall with your shoulders down and hips square to the front.
  4. Bend both knees and sink straight down until the back knee is just above the floor. Let the front knee travel forward over the middle toes while the front heel stays down.
  5. Drive through the whole front foot to stand back up, keeping the torso upright and the dumbbells hanging straight down.
  6. Finish each rep tall with both legs nearly straight, without moving your feet, and re-brace before the next rep.
  7. Complete all reps on one side, step the back foot forward to stand, then switch legs.
Coaching cues
  • Sink straight down, back knee towards the floor
  • Push the floor away through the whole front foot
  • Front knee over the middle toes
  • Chest tall, hips square to the front
  • Weight on the front leg, back foot for balance

In VALDA, these cues are one tap away on the exercise while you train.

Common faults

What goes wrong, and the fix

Stance too short

Fix: Lengthen the stance so both knees reach about 90° at the bottom, front heel down.

Feet on one line

Fix: Set the feet hip-width apart, as if on two rails, before the first rep.

Front knee caving inward

Fix: Keep the front knee tracking over the middle toes for the whole rep.

Driving off the back foot

Fix: Keep most of your weight on the front foot and use the back foot for balance.

Cutting depth short

Fix: Sink until the back knee is just above the floor on every rep.

Torso folding forward

Fix: Brace, stay tall and let the dumbbells hang straight down at your sides.

What the research says

Muscle growth · first choiceGeneral fitness · first choiceStrengthRehab & prehabSport performanceEnduranceFat loss & conditioning

  • 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 split squats before the legs do.
  • 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.
  • Rest and sides — In trained lifters, rests of about 3 minutes have produced greater strength and size gains than 1-minute rests. A common approach is to finish all reps on one leg, switch, then rest after both sides.
