Stretching a pulled groin safely starts with timing. In the first one to three days after the injury, your priority is protecting the muscle, not stretching it. Once that initial window passes and pain begins to settle, gentle stretching combined with gradual loading is the most effective path back to full mobility. The key throughout is simple: stretch to mild tension, never into pain.
What’s Actually Injured
A groin strain is a tear in one or more of the five muscles that run along your inner thigh. These muscles, called the adductors, pull your leg inward toward your body’s center line. They also help with hip flexion, rotation, and stabilizing your pelvis during walking and running. The most commonly strained is the adductor longus, which sits near the top of the inner thigh close to the pubic bone.
Strains are graded on a three-point scale. A Grade 1 strain causes pain but you keep most of your strength and range of motion. A Grade 2 means noticeably compromised strength. A Grade 3 is a complete tear with loss of muscle function. The grade matters because it determines when stretching is safe and how aggressively you can progress. Grade 1 strains typically allow gentle stretching within a few days. Grade 2 injuries need a longer protected period. Grade 3 tears often require medical evaluation before any rehab begins.
Before You Stretch: The First Few Days
Current sports medicine guidance follows what’s known as the PEACE and LOVE framework. In the immediate aftermath of a groin strain, the “PEACE” phase applies: protect the area by limiting movement for one to three days, compress with a bandage to control swelling, and let pain signals guide when to stop resting. Prolonged rest beyond those first few days actually weakens the healing tissue, so the goal is to transition to gentle movement as soon as symptoms allow.
One counterintuitive recommendation: avoid anti-inflammatory medications in the early days. The inflammatory response is part of how your body repairs damaged muscle fibers, and suppressing it with medication, especially at higher doses, may compromise long-term healing. Ice falls into the same category of caution. Focus instead on compression and relative rest.
The “LOVE” phase kicks in next. Load the muscle early with pain-free movement, start light aerobic exercise to increase blood flow, and begin stretching to restore mobility. Pain is your guide at every step. If a stretch hurts, you’ve gone too far.
Butterfly Stretch
This is one of the gentlest ways to open up the inner thigh and is a good starting point once you’re past the initial protection phase.
- Setup: Sit on the floor with the soles of your feet pressed together in front of you. The closer your feet are to your hips, the deeper the stretch, so start with them farther away and adjust.
- Position: Root your weight into your sitting bones and straighten your spine. Tuck your chin slightly.
- Stretch: With each exhale, let your knees relax toward the floor. Don’t push them down with your hands. Let gravity and your breathing do the work.
- Duration: Hold for up to 2 minutes. Repeat 2 to 4 times.
If sitting on the floor feels too intense, place a folded towel or pillow under your hips to reduce the stretch angle. You should feel a gentle pull along your inner thighs, not a sharp or burning sensation.
Standing Side Lunge Stretch
This stretch targets the adductors in a standing position, which makes it practical for warming up before activity or fitting into your day without getting on the floor.
- Setup: Stand with feet wider than shoulder-width apart, toes pointing forward or slightly outward. Place your hands on your hips or hold a chair for balance.
- Position: Shift your weight to one leg, bending that knee, while keeping the opposite leg straight. You should feel a gentle stretch along the inner thigh of the straight leg.
- Hold: Maintain the position for 15 to 30 seconds, breathing deeply. Don’t bounce or force the stretch.
- Repeat: Return to center, then switch sides. Do 2 to 3 repetitions per leg.
Keep your torso upright throughout. Leaning or rotating your trunk reduces the effectiveness of the stretch and puts unnecessary strain on your lower back. Breathe steadily, exhaling as you sink slightly deeper into the lunge.
Frog Stretch
The frog stretch is more advanced and delivers a deeper opening through the inner thighs and hips. Save this one for later in your recovery when the butterfly and side lunge feel comfortable and pain-free.
- Setup: Start on all fours on a mat or soft surface. Place a folded blanket under your knees for cushioning.
- Position: Slowly walk your knees apart, wider than your hips. Turn your feet outward so the inner edge of each foot rests on the floor. Aim to line up your ankles with your knees, creating roughly 90-degree angles at each knee.
- Deepen: Stay on your hands for a lighter stretch, or lower down onto your forearms for more intensity.
- Duration: Hold anywhere from 30 seconds to several minutes, depending on your comfort. To come out, rise back onto your palms and walk your knees together.
Engage your core by drawing your belly button toward your spine. This protects your lower back from sagging. If you have any knee pain or difficulty getting up and down from the floor, skip this stretch entirely.
How Long to Hold Each Stretch
The American College of Sports Medicine recommends spending a total of 60 seconds on each stretching exercise for optimal results. You can break that up however works for you: four holds of 15 seconds, three holds of 20 seconds, or two holds of 30 seconds all accomplish the same thing. The butterfly stretch is an exception since it’s gentle enough to hold for up to 2 minutes at a time.
Stretch at least two to three times per week, though daily stretching during recovery from a groin strain is typically more effective. Always warm up first. Five minutes of walking or light cycling increases blood flow to the muscles and makes stretching safer and more productive. Avoid deep static stretching right before strength training or explosive activity, as it can temporarily reduce the muscle’s ability to generate force.
Progressing Beyond Stretching
Stretching restores flexibility, but it’s only one piece of recovery. The adductors need to rebuild strength and tolerance to load, or you’re likely to strain them again. Once stretching feels easy and pain-free, start adding light strengthening exercises: side-lying leg lifts, gentle squeezes of a pillow between your knees, and eventually lateral lunges with resistance.
Pain-free aerobic exercise, like walking or stationary cycling, should begin within a few days of the injury. It boosts blood flow to the damaged tissue and supports the overall healing process. People who experience repeated groin strains are more likely to develop a sports hernia, a deeper injury to the lower abdominal wall that causes chronic pain and is harder to resolve. Building strength alongside flexibility is the best way to prevent that cycle.
Signs the Injury Is More Serious
Not all groin pain is a simple muscle strain. Seek immediate medical attention if you notice bleeding in or around the groin, inability to move your leg or hip, swelling that keeps getting worse, coldness or skin color changes in the leg, or numbness and tingling. These symptoms can point to a fracture, significant internal bleeding, or vascular injury. Even without those red flags, pain that persists after a few weeks of home treatment warrants a medical evaluation. An MRI can rule out bone fractures, complete tendon tears, or a sports hernia that might be masquerading as a strain.
