Groin · Acute Adductor Strain

Groin Strain

You’ve strained one of the muscles on the inner side of your thigh. You’ve overstretched it and partly torn it, usually near where it attaches at the top of your thigh. It’s the classic ‘groin pull’ from kicking and quick changes of direction. Most are partial tears that recover well with the right exercises.

The adductors get injured when they’re loaded hard while lengthening: a kick, a sharp cut, a slip where the leg gets dragged outward. The fix is not rest. Gentle squeezes that build into real strengthening for the inner thigh, hips, and core are what actually get people back to full activity.

How it typically shows up

Medial groin / inner-thigh pain at the adductor origin after an acute kick, change-of-direction, slip, or sprint, with adductor tenderness AND pain reproduced on resisted adduction (the squeeze test). That is the Doha-agreement definition of adductor-related groin pain. It applies once a sports/inguinal hernia, an iliopsoas (hip-flexor) source, deep hip-joint (FAI) pain, and the visceral/avulsion warning signs are excluded.

How long recovery takes

Expect a step-by-step comeback over a few weeks. You’ll settle things down and start with gentle squeezing holds, then gradually build up the strength of that inner-thigh muscle alongside balanced hip and core work, then rebuild the higher-load activity you selected. Each stage is unlocked by being pain-free, not by the calendar, and most people get back to full activity.

The phased recovery approach

  1. Phase 1 · 1–2 weeks

    Calm

    Settle the strain down first, it has to stop being touchy before it can take real load. Gentle squeeze-and-hold work is fine, but don’t aggressively stretch a fresh strain.

    What you get back: walking without the groin twinge.

    • Hip Internal/External Rotation — 1–2 sets × 8–10 reps · Sit on the floor and rock both knees side to side (windscreen-wiper).
    • Gentle Adductor Stretch — 2–3 sets × 10–20s hold · Sit with the soles of your feet together (butterfly), or stand and shift your weight onto one leg.
    • Isometric Adductor Squeeze — 2–3 sets × 10–20s hold · Lie on your back with your knees bent and feet flat.
    • Standing Adductor Ball Squeeze — 2–3 sets × 10–20s hold · Stand tall with a ball or rolled towel between your knees.

  2. Phase 2 · 2–6 weeks

    Rebuild

    Now build real strength into the inner thigh so it can take load without giving out.

    What you get back: inner-thigh strength for harder movement.

    • Adductor Squeeze at 90° + extended — 2–3 sets × 15–30s hold · Lie on your back and place a ball or your fist between your knees.
    • Isometric Adductor Squeeze — 2–3 sets × 15–30s hold · Lie on your back with your knees bent and feet flat.
    • Cable / Machine Hip Adduction — 2–3 sets × 10–15 reps · Use a cable with an ankle strap, or the seated adductor machine.
    • Banded Standing Hip Adduction — 2–3 sets × 10–15 reps · Anchor a band at ankle height to the side.

  3. Phase 3 · 2–4 weeks

    Back to running

    Rebuild comfortable straight-line running without turning your goal into a cutting sport.

    What you get back: back to comfortable running.

    • Groin Walk-Jog Build — 1 sets × 600–1200s hold · On flat ground, jog easily for a short stretch.
    • Standing Adductor Ball Squeeze — 2–3 sets × 20–30s hold · Stand tall with a ball or rolled towel between your knees.
    • Adductor Squeeze at 90° + extended — 2–3 sets × 20–30s hold · Lie on your back and place a ball or your fist between your knees.
    • Weighted Copenhagen Plank — 2–3 sets × 6–10 reps · Set up the long-lever Copenhagen with your top foot on a bench.

  4. Phase 4 · 1–3 weeks

    Back to daily life

    Keep the groin, hip, and core strong enough that everyday life stays easy and pain-free.

    What you get back: everyday life, pain-free.

    • Graded Walking — 1 sets × 600–1800s hold · Walk on flat ground at an easy, comfortable pace.
    • Standing Adductor Ball Squeeze — 2–3 sets × 20–30s hold · Stand tall with a ball or rolled towel between your knees.
    • Adductor Squeeze at 90° + extended — 2–3 sets × 20–30s hold · Lie on your back and place a ball or your fist between your knees.
    • Weighted Copenhagen Plank — 2–3 sets × 6–10 reps · Set up the long-lever Copenhagen with your top foot on a bench.

  5. Phase 5 · 2–5 weeks

    Back to the gym

    Build the inner thigh up to full training load so the gym stops being a risk to it. Take each step only when the groin stays pain-free during and after.

    What you get back: lifting and training again.

    • Cable / Machine Hip Adduction — 3–4 sets × 8–12 reps · Use a cable with an ankle strap, or the seated adductor machine.
    • Banded Standing Hip Adduction — 3–4 sets × 8–12 reps · Anchor a band at ankle height to the side.
    • Side-Lying Hip Adduction — 3–4 sets × 8–12 reps · Lie on your injured side with your top leg crossed in front.
    • Lateral Lunge — 3–4 sets × 8–12 reps · Step out wide to one side.

Exact exercises, sets and progression depend on your severity, equipment and goal — this is the shape of the program, not a one-size prescription.

What matters while you recover

  • Strengthen it, don’t just rest and stretch

    Groin strains recover with active strengthening, not rest and stretching. Build the load steadily and move up a level only when the current one feels easy and pain-free.

  • Keep it (almost) pain-free

    Keep the exercises essentially pain-free and don’t dull the pain before a session. A fresh strain is stricter than tendon soreness rules, so don’t work through pain.

Common questions

Should I just rest it and stretch?
No, that’s the old approach and it left groins lingering. The evidence is that an ACTIVE strengthening program recovers an adductor strain, while passive treatment and stretching alone often doesn’t. Keep stretches gentle and pain-free. The strengthening is what heals it.
How much pain is okay during the exercises?
Keep it essentially pain-free. A little controlled discomfort that settles quickly is fine, but never push into real pain. A muscle strain is not a tendon problem, so the more permissive tendon pain rule doesn’t apply here.
How do I know it’s the adductor and not something else?
The giveaway is that squeezing your knees together reproduces the INNER-thigh pain. Pain at the front hip crease on lifting the knee points to the hip flexor. Pain in the lower-belly crease that’s worse coughing points to a hernia. Deep joint pain on pivoting points to the hip itself. Those are different problems.
