Should my rear knee touch the floor during split squats?

Your rear knee should come close to the floor but does not need to make contact. Stopping just above the floor maintains tension on the muscles while avoiding discomfort or bruising.

What is the difference between a split squat and a lunge?

A split squat is performed from a static stance with no stepping movement, while a lunge involves stepping forward or backward into position. The static position of the split squat allows for better balance and more controlled loading of the front leg.

How far forward should my front foot be in a split squat?

Your front foot should be far enough forward that when you lower into the bottom position, your shin remains vertical or near-vertical and your front knee stays over your ankle. This typically requires a stride length of approximately two to three feet depending on your height.

Split Squat (Dumbbell)

The dumbbell split squat is a unilateral leg exercise performed from a static lunge stance, lowering and raising the body while holding dumbbells at your sides. It suits lifters seeking to build quadriceps and glute strength while addressing muscle imbalances between legs.

Muscle group: Legs
Primary muscles: quadriceps, glutes
Equipment: Dumbbell

How to do the Split Squat (Dumbbell)

Hold a dumbbell in each hand at your sides and step one foot forward into a long lunge stance, keeping your rear heel off the ground.
Position your feet hip-width apart laterally to maintain balance, with your torso upright and core braced.
Lower your body by bending both knees until your rear knee approaches the floor and your front thigh is roughly parallel to the ground.
Press through your front foot to drive back up to the starting position, keeping your weight centered over your front heel.
Complete all reps on one leg before switching to the other side.

Form tips

Keep your front shin as vertical as possible at the bottom to maximize quad engagement and reduce knee stress.
Maintain an upright torso throughout the movement rather than leaning forward, which shifts emphasis away from the quadriceps.
Drive through the heel and midfoot of your front leg rather than the toes to ensure proper force distribution.

Common mistakes

Stepping too short creates a narrow stance that forces the front knee excessively forward past the toes, increasing joint stress.
Allowing the front knee to cave inward reduces glute activation and places harmful lateral stress on the knee joint.
Pushing off the rear foot to assist the movement diminishes the training effect on the working leg and defeats the unilateral purpose.

Sets and reps

For strength, perform 3 to 4 sets of 6 to 8 reps per leg with heavier dumbbells; for hypertrophy, use 3 to 4 sets of 8 to 12 reps per leg with moderate weight.
