Lunge
How to lunge as a beginner: step length, knee tracking, the back knee touch, fixing balance and four scaling steps from supported reverse lunges up.
What the lunge is
The lunge is a single leg squat pattern: you step forward or back, lower until the back knee lightly touches or nears the floor, then return to standing. It trains leg strength one side at a time, balance and hip stability. A beginner starts with bodyweight reverse lunges, holding something steady if needed, before adding walking lunges or weight.
Why it is in class
CrossFit uses the lunge because real life is rarely symmetrical. Climbing stairs, stepping over a log on a trail, getting down to one knee to tie a shoe or pick up a child: all of these load one leg more than the other. Lunges build strength on each side independently, which can reveal imbalances that two leg squats hide. They also challenge balance and the smaller muscles around the hips and knees. In workouts, walking lunges, front rack lunges and overhead lunges show up often, so learning a stable pattern early lets you handle volume and load later. For beginners, the lunge is a gentle way to build leg strength using nothing but body weight.
Points of performance
What a good rep looks like, from setup to finish.
Stand tall, step far enough
Start standing with feet hip width apart. Step back or forward far enough that both knees can bend to roughly a right angle at the bottom. Too short a step crowds the front knee, and too long a step stretches you out and makes you wobble.
Lower straight down
Drop your back knee straight toward the floor rather than lurching forward. Your torso stays upright and your hips stay square to the front, with your weight centered over the heel and midfoot of the front foot.
Front knee tracks the toes
Keep your front knee in line with your second and third toes. It can move forward a bit, but it should not collapse inward. Press the whole front foot into the floor so the big toe and heel both stay down.
Touch, do not crash
In CrossFit workouts, a standard lunge rep counts when the back knee touches the ground lightly. Touch it under control, and use a pad or folded mat under the knee to make that contact comfortable.
Drive up through the front foot
Push through the front heel and midfoot to stand, bringing your feet together at the top or stepping into the next walking lunge. Finish with hips and knees fully extended before you start the next rep.
Common beginner faults, and the fix
Knee caves inward
What it looks likeThe front knee drifts toward the midline as the lifter lowers or stands up.
The fixCue front knee out over the toes. Slow the rep down and use an easier variation until you can control the knee path.
Torso pitches forward
What it looks likeThe chest drops toward the front thigh and the lifter reaches out for balance.
The fixLift your chest and keep your shoulders over your hips. A reverse lunge is often easier to keep upright than a forward lunge.
Tightrope stance
What it looks likeThe feet line up one directly in front of the other, causing wobbles and a sideways lean.
The fixKeep your feet roughly hip width apart, as if stepping on two separate train tracks rather than one rope.
Back knee slams the floor
What it looks likeThe lifter drops into the bottom and the knee bangs down hard.
The fixLower under control and touch lightly. Shorten your range with a stack of pads until you can control the full depth.
Where you start, and where it goes
Every movement in class has a version that fits you today.
Start here
Bodyweight reverse lunges holding a rig, wall or PVC pipe for balance, to a pad or partial depth.
Next step when: You can do 10 controlled reps on each leg with the front knee tracking well and the back knee touching softly.
Building
Unsupported reverse lunges and walking lunges with bodyweight, then light dumbbells held at your sides.
Next step when: Your balance holds and you can complete walking lunges for distance without losing position.
Full movement
Walking or alternating lunges with a barbell in the front rack, a barbell on the back, or dumbbells, as a workout calls for.
Next step when: Load increases steadily while your torso stays upright and your knees track.
Beyond
Overhead lunges with a plate, dumbbell or barbell, higher volume lunges, and heavier loaded lunges in strength work.
Next step when: Your coach will add overhead and heavier variations once balance and shoulder stability are clearly established.
Learning it in your first classes
In early coached classes, the lunge usually shows up in warmups or as a scaled option, and your coach will often start you with reverse lunges because they are easier to balance. They will watch your front knee, your step length and whether your torso stays tall. You may get a pad to place under your back knee. Tell your coach about knee pain, especially pain around the kneecap or a past knee injury, so they can adjust depth or swap the movement. Ongoing knee pain is worth checking with a doctor or physical therapist.

Questions beginners ask
Should my back knee touch the floor in a lunge?
In most CrossFit workouts, a lunge rep counts when the back knee touches the ground lightly. Touch it under control rather than dropping onto it. A pad or folded mat under the knee makes this comfortable. If you cannot reach the floor yet, your coach can raise the target with a stack of pads.
Are reverse lunges easier than forward lunges?
Reverse lunges are usually easier for beginners than forward lunges because stepping back keeps your weight over the front foot and makes balance more manageable. Forward lunges ask you to absorb momentum. Starting with reverse lunges builds the pattern, and walking lunges and forward lunges follow.
Why do lunges hurt my knees?
Knee discomfort in lunges can come from the front knee caving inward, too short a step, or slamming the back knee down. Fix the step length, track the knee over the toes and slow the rep. If pain continues, tell your coach and check with a doctor or physical therapist about your knee.
How do I keep my balance during lunges?
Balance in lunges starts with a hip width stance, as if each foot is on its own train track. Keep your eyes forward, brace your trunk and move slowly. Holding a wall or rig for the first few sessions is a fine way to learn the lunge, and balance usually improves with steady practice.
