Most runners think they have a knee problem. Or maybe a "shins" problem. They spend hundreds of dollars on maximalist shoes and carbon plates, hoping the tech will save their joints from the pounding of the pavement. But honestly? The problem is usually a few inches higher up. If your pelvis is tilting like a seesaw every time your foot hits the ground, no amount of foam is going to fix that. It’s about your hips. Specifically, it's about how hip strength exercises for runners create a stable foundation that stops your lower body from collapsing inward.
I’ve seen it a thousand times. A runner hits 15 miles a week and feels great, then tries to jump to 25, and suddenly their IT band feels like a hot poker is being pressed into their thigh. They stretch. They foam roll until they’re bruised. They do everything except the one thing that actually matters: strengthening the gluteus medius and the deep lateral rotators.
Running is essentially a series of single-leg hops. Every time you land, your body has to absorb roughly three to four times your body weight. If your hips are weak, your knee dives inward (valgus stress), your arch collapses, and your lower back takes the hit. It's a chain reaction. If the anchor—the hip—is loose, the whole ship tosses.
The Science of the "Trendelenburg Gait" and Why It Ruins You
You've probably seen that runner in the park whose hips drop significantly on one side every time they take a step. In clinical circles, we call this a Trendelenburg gait. It’s usually a sign that the hip abductors, particularly that pesky glute medius, aren't doing their job of keeping the pelvis level. When that pelvis drops, it creates a "functional leg length discrepancy." Basically, your body thinks one leg is longer than the other for a split second, and it compensates by twisting your knee and ankle.
A famous study by Dierks et al. (2008) looked at runners with patellofemoral pain syndrome—basically "runner's knee"— and found a significant correlation between hip abductor weakness and pain levels. The weaker the hips, the more the knee hurt. It wasn't the knee's fault. The knee was just the victim of a lazy hip.

Why standard squats aren't enough
People tell you to squat. Squats are great! They build big prime movers like the quads and the gluteus maximus. But running happens in the "frontal plane" too. We need to resist side-to-side motion. Most runners have plenty of "forward" strength but almost zero "side" stability. If you only move forward and backward in your training, you’re leaving a massive gap in your armor. You need to get weird with it. You need to move laterally.
Hip Strength Exercises for Runners That Actually Work
Forget those complicated machines at the gym. Most of the best work happens on the floor or with a simple resistance band. You want to target the small stabilizers that hold your femur in place.
The Monster Walk (The Burn You’ll Hate-Love)
Put a mini-band around your ankles. Not your knees—your ankles. It creates a longer lever and makes the muscles work harder. Get into a quarter-squat. Now, walk sideways. Keep your toes pointed straight ahead. Most people cheat by turning their feet out like a duck. Don't do that. Keep your chest up and feel that deep ache in the side of your butt. That’s your glute medius finally waking up. Do 20 steps right, 20 steps left. It should feel kinda miserable by the end.
The Copenhagen Plank
This one is for the adductors—the inner thigh. Everyone forgets the inner thigh, but it’s the counterpart to the outer hip. If one is strong and the other is weak, you’ve got an imbalance. Find a bench. Put your top leg on the bench and your bottom leg underneath it. Lift yourself up so you’re supported by your elbow and your top leg. This is hard. Really hard. It targets the pubic symphysis area and prevents that nagging "groin strain" that keeps people sidelined for months.

Single-Leg Deadlifts (The Balance King)
Running is a single-leg sport. So, train on one leg. Stand on your left leg, keep a slight bend in the knee, and hinge at the hips while reaching your right leg back. Your body should look like a "T." If you’re wobbling, that’s good. That’s your nervous system learning how to stabilize. Use a light kettlebell if you want, but bodyweight is plenty to start. Focus on keeping your hips "square" to the floor. If your right hip starts pointing toward the wall, you’ve lost the movement.
The "Clamshell" Trap
Look, clamshells are fine for rehab. If you’ve just had surgery or you're literally starting from zero, go for it. But for a runner who is already pounding the pavement for miles? Clamshells are often too easy. You need load. You need gravity. Instead of side-lying clamshells, try Side-Lying Leg Raises with the bottom leg bent and the top leg slightly behind your body line. Touch your heel to the wall behind you as you lift. It engages the posterior fibers of the glute medius, which are the ones that actually stop your knee from caving in.
How Often Should You Actually Do This?
You don't need a "Hip Day." That’s overkill.
Consistency beats intensity every single time in the world of physical therapy. Honestly, ten minutes of focused hip work three times a week is better than one hour-long session once a month. Think of it like brushing your teeth. It’s just "pre-hab."

- Monday: 5 minutes of monster walks and single-leg balance before your run.
- Wednesday: 10 minutes of eccentric step-downs and Copenhagen planks.
- Friday: A full "glute circuit" after your easy run.
Dr. Reed Ferber, a leading researcher at the Running Injury Clinic, has shown that even just six weeks of targeted hip strengthening can significantly reduce pain in runners. Six weeks. That’s nothing in the grand scheme of a running career.
Dealing with the "Deep Butt Pain"
Sometimes, runners get this literal pain in the butt. Usually, they think it's sciatica. Sometimes it’s Piriformis Syndrome. The piriformis is a tiny muscle that rotates the hip. When the big glute muscles are weak, this tiny little muscle tries to take over the job of stabilizing the whole hip. It gets overworked, gets tight, and starts pressing on the sciatic nerve.
The "fix" isn't just stretching the piriformis—which most people do incorrectly anyway. The fix is strengthening the glutes so the piriformis can go back to its day job. If you just stretch a tight, weak muscle, you're often just making it more unstable. Build the wall; don't just pull on the bricks.
Actionable Steps for Your Next Run
Stop reading and actually do something about your "niggles." If you’ve been feeling a weird ache in your hip or knee, here is your plan for the next 48 hours:
- Test yourself. Stand on one leg in front of a mirror. Do a single-leg squat. Does your knee dive toward the middle? Does your opposite hip drop? If yes, you have a hip stability issue.
- Buy a mini-band. They cost like five bucks. Keep it by your bed or your treadmill.
- The "Pre-Run" Activation. Before your next run, do 10 lateral leg raises on each side and 10 "bird-dogs." It "turns on" the muscles so they actually fire when your foot hits the dirt.
- Watch your cadence. Weak hips often lead to overstriding. If you increase your step rate (cadence) by just 5%, you reduce the load on your hips and knees significantly. Use a metronome app if you have to.
You don't need a gym membership to fix your running form. You just need to stop ignoring the muscles that keep your pelvis level. Strength is the best injury prevention. Go get some.
