Lunges: The Underrated Movement That Will Change the Way You Train
I’ll be straight with you — lunges don’t get nearly the respect they deserve. Walk into almost any gym and you’ll see people lined up at the squat rack or the leg press machine, but the lunge? Overlooked. Underutilized. Treated like some kind of warm-up exercise you do before the “real” training starts. After more than 30 years of working with clients ranging from retired athletes to people just getting off the couch for the first time, I can tell you with confidence — that’s a mistake.
The lunge is one of the most functional, versatile, and honestly humbling movements you can put in a training program. I’ve had guys walk in thinking they were in great shape, load up a barbell for squats no problem, and then nearly fall over doing a basic bodyweight lunge. It exposes weakness fast. And that’s exactly why it’s so valuable.
What Lunges Are Actually Doing for Your Body
Before we get into the how, let’s talk about the why. A lunge is what’s called a unilateral movement — meaning you’re working one leg at a time. That distinction is more important than most people realize. When both feet are on the ground in a squat, your stronger leg can compensate for your weaker one without you even knowing it. A lunge takes that away. Each leg has to carry its own weight, literally.
This is why lunges are so effective at identifying and correcting muscular imbalances. And trust me, almost everybody has them. After years of sitting at desks, favoring one side during sports, or just the natural asymmetries life creates — left and right sides of your body are rarely equally strong. Lunges bring that truth to the surface pretty quickly.
Muscles worked in a lunge include the quadriceps, hamstrings, glutes, hip flexors, calves, and the deep stabilizing muscles of your core and ankle. That’s a lot of territory for one movement. Research from the Journal of Human Kinetics has shown that forward lunges produce greater glute activation than standard squats in many individuals — which matters a lot if building posterior chain strength and protecting your lower back are priorities. And for adults over 50, they absolutely should be.
The Bodyweight Lunge: Start Here, No Exceptions
Same as with squats — you earn the right to add weight by demonstrating you can do the movement correctly without it first. I don’t bend on this with clients and I’m not going to bend on it here either.
Here’s your basic forward lunge. Stand tall, feet about hip-width apart, core braced. Take a controlled step forward with one foot — about 2 to 2.5 feet depending on your leg length. Lower your back knee toward the floor, stopping just before it touches. Your front shin should be relatively vertical, front knee tracking over your second or third toe. Then push through your front heel to return to the starting position. That’s one rep.
Sounds simple. Feels different in practice.
The mistakes I see most often are letting the front knee cave inward, leaning too far forward at the torso, and stepping too short — which puts excessive stress on the front knee rather than loading the glutes and hamstrings the way we want. Short steps are one of the biggest lunge errors out there and one of the easiest to fix once someone points it out.
Start with 3 sets of 10 reps per leg, three times a week. That’s it. Quality over quantity, always. Slow the descent down — take about 2 to 3 seconds on the way down — and you’ll feel the difference immediately. Your glutes and quads will let you know they’re working.
Lunge Variations to Build Strength Before Adding Load
There’s more than one way to lunge, and mixing up the variations keeps your training fresh while targeting muscles from slightly different angles. These are all bodyweight first — then we talk about adding resistance.
The Reverse Lunge is actually my starting point for most beginners and anyone with knee sensitivity. Instead of stepping forward, you step backward. This reduces shear force on the front knee considerably and gives you more control over the movement. If you’ve been told lunges bother your knees, try the reverse version first. Nine times out of ten, that solves it.
The Lateral Lunge steps out to the side rather than forward or back. This one targets the inner thigh, hip adductors, and glutes in a way that forward lunges simply don’t reach. It also improves hip mobility in the frontal plane — something most adults are severely lacking from years of only moving forward and backward. Take a wide step to one side, sit into that hip, keep the opposite leg straight, then push back to center.
The Walking Lunge is exactly what it sounds like — you lunge forward and keep moving rather than returning to start. This increases time under tension, challenges your balance more, and has a cardiovascular component that static lunges don’t. I used to have clients do walking lunges down the length of the gym floor and back. Some of them hated it in the moment. All of them thanked me for it later.
The Curtsy Lunge crosses the stepping foot behind and to the outside of the planted foot, almost like a curtsy. It’s a fantastic glute medius exercise and helps with hip stability in a way the standard lunge doesn’t address. Don’t let the name fool you — this one is tough.
Adding Weight: Dumbbells, Barbells, and Kettlebells
Once your bodyweight lunge mechanics are clean — and I mean really clean, not just “good enough” — then we start loading the movement. And there’s a right order to this.
Dumbbells held at your sides are the natural first step. They add resistance without disrupting your balance too dramatically and allow your arms to hang in a natural position. For most adults returning to training, starting with 10 to 20 pounds per hand is a reasonable range. Work up to 3 sets of 10 per leg with a weight that makes the last couple reps genuinely challenging, then increase by 5 pounds when that becomes manageable.
Goblet position — holding a single dumbbell or kettlebell at chest height — changes the challenge considerably. The front-loaded weight forces your core to work harder to keep you upright and actually helps reinforce good torso position. I like goblet lunges a lot for people who tend to lean forward excessively. Start lighter here than you think you need to. Seriously.
Barbell lunges are advanced territory. A barbell on your back during a lunge demands significant balance, core stability, and hip mobility. Rushed into too early, it’s a recipe for a twisted ankle or worse. But done right, with appropriate weight, barbell lunges build incredible leg strength and athleticism. Former athletes especially tend to respond well to this variation once they’ve rebuilt their base. Keep initial loads conservative — start with just the bar and earn every plate you add.
Weighted vest lunges are an excellent option that doesn’t get talked about enough. A 20 to 40 pound vest distributes weight evenly across your torso and keeps your hands free, which is great for balance during walking lunges. Simple, effective, and easier on your shoulders than a barbell for most people.
A realistic strength target for dumbbell lunges for adults over 50 — men working toward 40 to 50 pounds per hand for 3 sets of 8 to 10 reps is a solid, meaningful goal. Women working toward 20 to 30 pounds per hand in the same rep range. These aren’t records. They’re benchmarks for real functional strength that carries over into life.
Lunges for Joint Health and Longevity
Here’s something that doesn’t get said enough — lunges, done progressively and correctly, are fantastic for long-term joint health. The single-leg loading pattern strengthens the stabilizing muscles around the knee and hip in a way bilateral movements can’t fully replicate. A 2020 study in the International Journal of Sports Physical Therapy found that single-leg strengthening exercises significantly improved knee stability and reduced injury risk in active adults over time.
If you have a history of knee replacement, hip issues, or significant arthritis, I’d always recommend working with a qualified trainer or physical therapist before jumping in. But for most people dealing with mild joint discomfort or stiffness — progressive, controlled lunges are part of the solution, not the problem.
Your hips especially will benefit. Hip flexor tightness is an epidemic among adults who sit for a living, and the lunge stretch position directly addresses that. The trailing leg in a lunge gets a deep hip flexor stretch with every single rep. You’re simultaneously strengthening and lengthening. That’s a combination that keeps you moving well for decades.
What the Bible Says About Doing the Hard Thing
I want to take a second here, because lunges are genuinely hard. They’re uncomfortable. Your legs shake. Your balance gets tested. And there are plenty of days you won’t feel like doing them. I’ve been there myself.
But Galatians 6:9 says, “Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up.” That applies to training as much as anything else in life. The results come to those who stay consistent even when it’s inconvenient. Every lunge rep you push through when you don’t feel like it is an investment in the version of yourself that’s going to be strong, capable, and independent ten and twenty years from now.
That’s worth the temporary discomfort. Every single time.
Your Lunge Program: A Simple Starting Framework
Here’s a basic weekly framework to incorporate lunges without overdoing it early on. Three days per week, non-consecutive.
Day 1 — Reverse lunges, bodyweight, 3 sets of 10 per leg. Focus entirely on form. Slow descent, controlled return.
Day 2 — Forward lunges with light dumbbells, 3 sets of 10 per leg. Add 5 pounds every week or two as form stays solid.
Day 3 — Walking lunges, bodyweight or light weight, 3 sets of 20 total steps. This is your endurance day — keep rest short between sets, about 45 to 60 seconds.
Once you’ve built a foundation over 4 to 6 weeks, you can start layering in lateral lunges, goblet variations, and eventually barbell work if that’s appropriate for your goals. But build the base first. Always build the base first.
