An adductor strain heals best when you keep the inner thigh working and add load step by step, rather than resting it until the pain disappears.1PubMed. Traumatic muscle injury The muscle you strained does more than pull your legs together. It also steadies your pelvis every time you plant a foot and change direction. The path runs from gentle squeezes to heavy strength work and finally cutting drills, with the timing set by how the leg responds.
What You Have Strained and Why It Hurts When You Cut
The adductors are the inner-thigh muscles, and the one most often strained is the adductor longus, which brings the thigh toward the midline of your body.2AIRROSTI. What Muscles are Involved in Adductor Strains? In a cut, it works the whole time your foot is on the ground, not just at push-off.3PubMed Central. Adductor-Related Athletic Groin Pain: A Clinical Commentary It has to resist the leg being forced outward while it lengthens under that force.4PubMed Central. Adductor-Related Athletic Groin Pain: A Clinical Commentary Sudden side steps, wide lunges for a ball and slips are the typical moments of injury. Soccer, ice hockey and rugby all involve repeated cutting and kicking, so they account for many of these injuries.
In the moment, you usually feel a sharp pull or twinge high in the inner thigh during a stride or a cut. The next morning the area is stiff and tender near the groin crease, and bringing your knees together or getting out of a car hurts. In more serious strains, bruising can appear days later and travel down the inner thigh. A strain typically causes pain when you press on the inner-thigh tendons or where they attach to the pubic bone, often with pain when you squeeze your legs together against resistance.5PubMed Central. Groin Injuries in Sports Medicine
How Bad Is It Grading Your Strain
- Grade 1: pain but little loss of strength or movement.6PubMed Central. Groin Injuries in Sports Medicine
- Grade 2: real tissue damage that weakens the muscle without completely losing function.7PubMed Central. Groin Injuries in Sports Medicine
- Grade 3: the muscle or tendon is fully torn and the muscle can’t do its job.8PubMed Central. Groin Injuries in Sports Medicine
Some sports doctors also separate pain from overload or tightness, with no visible tear, from injuries where fibres are actually torn.9PubMed Central. Terminology and classification of muscle injuries in sport: The Munich consensus statement In the first days, a few simple checks give you a rough idea. Squeeze a pillow between your knees and note how much it hurts. See whether you can walk without limping, and whether stairs or getting into a car are painful. A pop at the moment of injury, a big bruise, or being unable to squeeze at all suggests a higher grade.
Day one is a poor time to settle on a grade. Swelling, muscle guarding and fear of pain can make a strain feel worse than it is. The more reliable clue is the direction of travel: a Grade 1 or mild Grade 2 strain usually eases noticeably over the first week, while pain that stays the same or worsens points to something more serious.
See a professional promptly if you suspect Grade 3 or felt a pop. Get checked too if the pain isn’t improving after two weeks, or if it sits in the lower belly or hip joint or flares when you cough, since those point beyond a simple strain.
Step 1 The First Few Days
After a day or two of avoiding painful moves, start gentle walking and easy movement.10PubMed. Traumatic muscle injury In the first two days, avoid sprinting, kicking and wide stretches. Ice for 15 minutes at a time if it helps. Between days 2 and 4, take short walks and move the hip gently without forcing a stretch. By the end of the first week, mild strains often allow pain-free walking and light squeezes. Let pain of about 3 out of 10 or less be your guide.
That guide works in practice like this: a mild ache that settles within an hour or so after movement means the load was acceptable. Sharp pain, limping, or soreness that is worse the next morning means you did too much, so drop back a step rather than push through. Check the leg both during an activity and the following morning, since delayed soreness is easy to miss.
Ice can take the edge off early pain, which makes gentle walking easier, but it is a comfort measure and doesn’t speed up tissue repair. Wrap it in a thin cloth rather than pressing it on bare skin, and stop if the skin becomes numb or very red.
Some mistakes set people back early. Stretching the inner thigh hard to “loosen it” can reinjure it. Complete bed rest lets the muscle weaken.
On painkillers, an animal study found that ibuprofen given right after tendon surgery weakened healing, while giving it later did not.11PubMed Central. The Detrimental Effects of Systemic Ibuprofen Delivery on Tendon Healing Are Time-Dependent That comes from tendon repair in animals, not human strains, but it is a reason to ask a doctor before relying on anti-inflammatories in the first days. Paracetamol and ice are alternatives for early pain relief.
Step 2 Waking the Muscle Up With Squeezes
Rehab should start with gentle isometric squeezes, which means holding a contraction without moving, with the leg in a short, unstretched position.12PubMed Central. Adductor Strains in Athletes It then progresses toward hard eccentric work, where the muscle lengthens under heavy load, with the leg stretched out.13PubMed Central. Adductor Strains in Athletes Each stage should feel manageable before you move on. Holding a squeeze lets you load the muscle without the sudden lengthening that caused the injury, and you can control the effort precisely.
Among common hip exercises, squeezing a ball between the knees produces the highest peak effort from the adductor longus.14Journal of Sport Rehabilitation. Adductor Longus Activation During Common Hip Exercises Side-lying lifts of the bottom leg keep it working hardest on average across the movement.15Journal of Sport Rehabilitation. Adductor Longus Activation During Common Hip Exercises Sumo squats, rotational squats and side lunges work it noticeably less.16Journal of Sport Rehabilitation. Adductor Longus Activation During Common Hip Exercises
For the ball squeeze, lie on your back with your knees bent and a ball or pillow between them. Squeeze at half effort for 5-10 seconds, and repeat 10 times. Build to full effort, then straighten your legs to make it harder. Move on when full squeezes are pain-free.
Squeeze with the inner thighs, keep your lower back relaxed and your pelvis level, and don’t let your hips tilt or your belly muscles take over. Keep breathing during the hold, because holding your breath adds tension and makes it harder to tell what the thigh is feeling. A mild ache is acceptable, but sharp pain in the groin means easing the effort or moving back a step.
For side-lying lifts, lie on the injured side with your top leg crossed in front. Lift the bottom leg a few inches and lower it slowly. Start with sets of 10 and add ankle weight later.
Step 3 Building Strength With the Copenhagen Exercise
The Copenhagen adduction exercise is a side plank with the top leg resting on a bench, so your inner thigh holds your body up.17Apunts Sports Medicine. The influence of Copenhagen adduction exercise on the management of groin pain: A systematic review It improves eccentric inner-thigh strength, hip movement and balance, and it reduces groin symptoms.18Apunts Sports Medicine. The influence of Copenhagen adduction exercise on the management of groin pain: A systematic review Regular training can thicken the adductors by about 18% and improve their flexibility.19PubMed Central. Effects of Copenhagen Adduction Exercise on Muscle Architecture and Adductor Flexibility Those gains fade when you stop doing it.20PubMed Central. Effects of Copenhagen Adduction Exercise on Muscle Architecture and Adductor Flexibility
This exercise asks the muscle to hold your body weight while it is stretched, which is closer to what happens in a cut. Start it only once full squeezes are pain-free.
Supporting the bench at the knee (the short lever) puts about a third less load on the muscle than supporting it at the ankle (the long lever).21PubMed Central. Biomechanics of Copenhagen Adduction Exercise and Eccentric Hip Adductor Exercises on a Novel Isokinetic Dynamometer With Within‐Session Repeatability So start with the knee version and move to the ankle version as you get stronger.
To set up the short-lever version, lie on your side with the top knee on a bench. Lift your hips into a side plank with the bottom leg hanging free. Hold for 10-20 seconds, or do slow lifts and lowers. Start with 2-3 sets, twice a week.
Keep your body in a straight line from shoulders to hips to knee, so your hips don’t drift forward or back. Press the top knee gently into the bench and lift with the inner thigh, rather than hauling yourself up with your arm or twisting. Support yourself on your forearm with the elbow under the shoulder, so the shoulder isn’t strained. You are ready to progress when you have no pain the next morning, both sides feel similar in strength, and you can do the exercise without your hips sagging.
Step 4 Running Cutting and Getting Back to Play
Cutting and pivoting load the adductors heavily, so they come last in rehab.22PubMed Central. Adductor-Related Athletic Groin Pain: A Clinical Commentary Compression shorts with directional support lowered inner-thigh effort during cuts, which may help in the late stages and early return.23PubMed Central. Hip adductor activations during run-to-cut maneuvers in compression shorts: Implications for return to sport after groin injury
The order is straight-line jogging, then faster running. Next come gradual side shuffles and gentle cuts, then kicking with short and then long passes. Full training comes before a match. Straight-line running puts much less sideways force on the inner thigh than changing direction does, so it tests the muscle more safely first.
Each step has a pass mark: move to the next drill only when the one before is done with no pain during it and no worse soreness the next morning. If a step flares the groin, go back one step for a few days rather than abandoning the plan. You are ready to play when full-effort squeezes, sprinting and cutting are pain-free, strength is equal on both sides, and training causes no next-day soreness.
For long-standing adductor groin pain, a 10-week exercise programme improved pain, strength and function.24PubMed Central. Effect of Holmich protocol exercise therapy on long-standing adductor-related groin pain in athletes: an objective evaluation In one programme, most athletes were back to full, pain-free sport in about 12 weeks.25PubMed Central. The Effect of Therapeutic Exercise on Long-Standing Adductor-Related Groin Pain in Athletes: Modified Hölmich Protocol In an earlier programme it took a median of about 18 weeks.26PubMed Central. The Effect of Therapeutic Exercise on Long-Standing Adductor-Related Groin Pain in Athletes: Modified Hölmich Protocol Among football players with adductor groin pain, about 89% returned to their previous level with exercise alone, similar to steroid or PRP injections.27Sports Traumatology & Arthroscopy.

When You Need Scans Injections or Surgery
Other problems, such as hip joint impingement, athletic pubalgia (sometimes called a sports hernia) and pubic bone inflammation, can feel like an adductor strain.28PubMed Central. Groin Injuries (Athletic Pubalgia) and Return to Play Clues that point beyond a simple strain include pain deep in the hip joint, clicking or catching, or pain that comes on with coughing or sit-ups.
A doctor will typically press along the tendon and pubic bone, test your squeeze against resistance, and check hip rotation and the lower abdomen. If a tear is suspected, they may order ultrasound or MRI.
Ultrasound detects partial and full tears well and is quicker and cheaper than MRI.29International Journal of Sports Physical Therapy. Diagnostic Musculoskeletal Ultrasound in the Evaluation of Adductor Longus Injuries: Implications for Rehabilitation Providers MRI may be needed for complex cases.30International Journal of Sports Physical Therapy. Diagnostic Musculoskeletal Ultrasound in the Evaluation of Adductor Longus Injuries: Implications for Rehabilitation Providers It shows deeper structures such as the hip joint and bone, so it helps when the cause is unclear or several problems may be present.
Even when the tendon tears off the bone, non-surgical treatment returned athletes to their previous level as often as surgery did.31PubMed. Surgical versus conservative management of traumatic proximal adductor longus avulsion injuries: A systematic review Non-surgical patients returned in about 2 months versus about 4 after surgery.32PubMed. Surgical versus conservative management of traumatic proximal adductor longus avulsion injuries: A systematic review Surgeons often consider repair when the torn end pulls back more than 2 cm.33PubMed. Patient-related outcome measurements after operative and conservative management of traumatic proximal adductor longus avulsion injuries
Keeping It From Coming Back
A previous groin injury and inner-thigh weakness compared with the other side raise the risk of a new strain.34PubMed. Acute Adductor Muscle Injury: A Systematic Review on Diagnostic Imaging, Treatment, and Prevention Finishing rehab fully, with strength matching the other side, matters more than simply being pain-free.
Low eccentric inner-thigh strength is a major risk factor.35Apunts Sports Medicine. The influence of Copenhagen adduction exercise on the management of groin pain: A systematic review Limited hip flexibility in other directions does not seem to raise risk.36PubMed Central. Is lower hip range of motion a risk factor for groin pain in athletes? A systematic review with clinical applications
Soccer teams doing a Copenhagen-based programme had about 41% lower risk of groin problems during the season.37International Journal of Sports Physical Therapy. The Neuromuscular Effects of the Copenhagen Adductor Exercise: A Systematic Review Pooled results from several studies show a smaller, less certain benefit.38PubMed Central. The Copenhagen Adduction Exercise Effect on Sport Performance and Injury Prevention: A Systematic Review With Meta‐Analysis Poor trunk and pelvis control can keep overloading the groin after injury.39Applied Sciences. Effects of a History of Adductor-Related Groin Pain on Kicking Biomechanics and HAGOS Subscales in Male Soccer Players: A Comprehensive Analysis Using 1D-SPM Studs that don’t suit the playing surface can grip too much and increase twisting strain.40Srino Bharam, M.D.. Does Playing Surface Matter? Turf vs. Grass and Groin Injury Risk in Football
A simple maintenance routine covers most of this. Do the Copenhagen exercise once or twice a week through the season, and include core and hip stability work. Test squeeze strength on both sides now and then, and pick studs that suit the surface you play on.
