The barbell rear lunge is a compound movement that loads the quads under a controlled stretch, building unilateral leg strength and size that bilateral lifts simply cannot replicate. Master it and you build the foundation for powerful, balanced legs that perform as well as they look.
Set the barbell across your upper traps with a firm grip, brace your core, and stand with feet hip-width apart.
Step one foot directly back and lower your rear knee toward the floor, keeping your front shin as vertical as possible.
Sink until your front thigh reaches parallel and your rear knee hovers just above the ground without touching.
Drive through your front heel to stand back to the starting position, fully extending the hip before the next rep.
Common mistakes
Letting the front knee cave inward under load — actively push your knee out in line with your second toe throughout the descent.
Taking too short a step back, which shifts load onto the calf and knee instead of the quad — step back far enough so your shin stays vertical.
Allowing the torso to collapse forward under the bar, losing tension and stressing the lower back — lock your ribcage down and maintain a tall spine from setup to finish.
Pro tip — On every rep, think about driving the floor away from you rather than pushing yourself up — this subtle cue recruits the quad more aggressively and keeps tension out of the lower back.
