Walking Lunge

Also called: Alternating walking lunge

Secondary muscles: Gluteus maximus, Adductors (hip adductor group)

Joints / actions: Knee joint (tibiofemoral joint) (extension); Hip joint (coxal joint) (extension)

Plane: sagittal

Equipment: bodyweight

What it is

Stepping forward into a lunge position, lowering the back knee toward the floor, then stepping through to repeat on the other leg.

Purpose

A unilateral (single-leg-dominant) exercise that builds quad and glute strength while challenging balance.

Starting position

Stand tall, feet together, core braced.

Step by step

Step forward with one leg and lower the body until both knees are bent near 90°, back knee hovering just above the floor.
Keep the front knee tracking over the foot and the torso upright.
Drive through the front foot to stand up and step through into the next lunge on the other leg.

Breathing

Inhale as you lower; exhale as you drive up to step through.

Coaching cues

"Tall torso, front knee over the ankle, drive through the front heel."

Common mistakes

Letting the front knee drift far past the toes with the heel rising; leaning the torso far forward; taking a step that's too short or too long.

Easier regression

Stationary (reverse) lunge instead of walking, or hold onto a support for balance.

Harder progression

Add dumbbells, or increase step distance/depth once balance and control are solid.

Alternatives

Reverse lunge, step-up, split squat.

Who may benefit

Anyone building single-leg strength and balance, including athletes in sports with a lot of single-leg movement.

Who should modify or avoid it

Those with balance limitations or significant knee pain in a lunge position should regress to a supported or stationary variation.

Why this exercise works

Working one leg at a time reveals and addresses side-to-side strength or balance differences, while still heavily loading the quadriceps and glutes through a full range of hip and knee motion.

⚠ Safety note

Use a shorter, more controlled step length while learning; hold a wall or rail if balance is limited.
