Groin Tightness That Won't Go Away? Here's Why — and What to Do Instead
Why stretching your groin might be making things worse — and the Postural Restoration approach that actually creates lasting change.
📹 If you caught my recent Instagram reel on adductor anatomy and left-right imbalance, this post goes deeper on everything I covered there — including the anatomy, the compensation pattern, and a step-by-step exercise to start fixing it.

Have you been dealing with groin pain or tightness that just won't go away — even after stretching and exercise? You're not alone. Groin strains and chronic tightness are some of the most common complaints we see in the clinic, and often people have been managing them for years with no lasting relief.
The reason the usual approaches don't work isn't a lack of effort. It's a lack of the right information. Most people don't understand why the tightness is there in the first place — and without that understanding, it's easy to choose exercises that not only miss the root cause but actually make things worse.
Let's fix that right now.
What Are the Adductor Muscles Really Doing?
To understand groin tightness, we first need to understand the adductor muscles, the group of muscles that run from your pubic bone and sit bones (ischial tuberosities) to the inside of your thigh.
Most people know them as the muscles that pull the thigh inward toward the midline of the body, the same motion as the adductor machine at the gym. But from a Postural Restoration (PRI) perspective, that's actually their secondary role.
Their most important job? Centering the pelvis over the leg during standing and walking.
Every single step you take, the adductors on your stance leg activate to shift your center of mass — your body weight — directly over that leg. As you step left, your left adductors pull the pelvis to the left. As you step right, your right adductors take over. Back and forth, thousands of times a day. In an ideal world, this system is balanced and both sides work equally.
Why the Traditional Approach Makes It Worse
In many of the patients we see, there is a meaningful imbalance between the left and right adductors. If someone habitually bears more weight on their right side, for example, the right adductors become short and overactive — constantly pulling the pelvis and center of mass to the right. The left adductors, meanwhile, get placed on a sustained stretch and have to overwork just to try to pull things back toward center.
Here's where the problem compounds: that overstretched left side feels tight. It feels like it desperately needs to be stretched. So people stretch it — every day, sometimes multiple times a day — and wonder why it never actually gets better.
Stretching a muscle that is already in a lengthened position doesn't fix the tightness. It can deepen the imbalance and give the already-shortened side even more mechanical advantage. Repeated over time, this pattern can lead to more serious muscle strains and tears.
💡 Key insight: Tightness and weakness are not always the root problem. The root problem is an imbalance in the system. Strengthening the weak side is better than stretching it — but retraining the whole pattern is better still.
The Missing Piece: Rotation
There's one more role of the adductors that most people, and many clinicians, never consider, and understanding it is essential to actually retraining them correctly.
The adductor magnus, the largest of the adductor muscles, running from the sit bone (ischial tuberosity) down the inside of the thigh, also rotates the pelvis toward the stance leg. Because this muscle runs from back to front as it travels down the leg, its contraction turns the pelvis toward that side — like turning the zipper of your pants toward the leg you're standing on.
This rotational role is why simply strengthening the adductors in isolation isn't enough. To truly retrain them, we have to put them in the right position to do all three of their jobs — centering the pelvis side to side, rotating the pelvis toward the stance leg, and supporting efficient weight transfer through every step.
How to Actually Fix It: The Adductor Pullback
The Postural Restoration Institute teaches a deceptively simple exercise called the Adductor Pullback — and it's one of the most effective starting points for retraining the adductors to restore balance and create lasting relief.
Here's how to do it, step by step:
1. Lie on your right side with your feet on the wall and your hips and knees bent at a 90 degree angle.
2. Place a large towel roll between your ankles and a smaller towel roll between your knees. Your top ankle and hip should be at the same height, and your knee should be slightly lower.
3. Push your feet lightly into the wall so they don't move.
4. Tuck your hips under you into a slight posterior pelvic tilt. Your low back should round gently and your belly button should move backward.
5. Breathe in through your nose and activate your left groin to shift your left knee back so it moves behind your right.
6. Exhale and squeeze your left knee downward, keeping it shifted back as you do. You should feel a muscle contraction high up in your groin. It may even feel like it's about to cramp. That's okay, this improves as you retrain the muscle.
7. Continue this sequence for 4 breaths, shifting the top leg back a little further with each breath. Stop if you feel your back taking over.
8. After 4 breaths, rest and relax. Repeat the exercise 4 more times.

What does this exercise actually do?
By shifting the leg backward, we teach the pelvis how to rotate toward the stance leg. By squeezing the knee down, we teach the pelvis how to shift laterally over the stance leg as the adductors shorten. Practiced consistently, the body learns how to activate and deactivate the groin muscles appropriately as weight shifts side to side.
The overstretched side starts to feel better because it's no longer constantly in a lengthened position. The shortened side starts to feel better because it learns to release as weight transfers to the other leg. Restoring balance in muscle activity reduces tightness and discomfort on both sides.
⚠️ Important: This exercise is a starting point and works well for many people, but chronic groin tightness can have multiple contributing factors. If you've been dealing with this for a long time or have associated hip, back, or knee symptoms, a one-on-one evaluation will give you a much clearer picture of what's driving your specific pattern.
The Most Important Takeaway
If you've been dealing with tight and painful groin muscles and stretching and strengthening haven't helped, it's likely because the root cause hasn't been addressed. Tightness on one side and weakness on the other are symptoms of an imbalance — not the cause of it.
To truly fix the problem, we have to evaluate what's happening on each side of the body and treat the system as a whole. The next time you feel groin tightness, before you reach for a stretch, ask yourself: is this actually going to fix the pattern, or just temporarily quiet the symptom?
If you're not sure — that's exactly what we're here for.
