Groin Strain Exercises: Adductor Injury Recovery

What Is a Groin Strain?

A groin strain is an injury to the adductor muscles — the muscles on the inner thigh that pull your leg inward.

Commonly injured:

  • Adductor longus (most common)
  • Adductor magnus
  • Adductor brevis
  • Gracilis
  • Pectineus
  • Symptoms:

  • Pain in inner thigh/groin
  • Pain with kicking, cutting, sprinting
  • Tenderness to touch
  • Bruising (sometimes)
  • Weakness with leg adduction
  • Why Groin Strains Happen

    High-Risk Activities

  • Rapid direction changes
  • Kicking
  • Skating
  • Sliding/lunging
  • Overstretching
  • Risk Factors

  • Previous groin injury
  • Weak adductors
  • Poor hip mobility
  • Hip muscle imbalances
  • Inadequate warm-up
  • Treatment Phases

    Acute Phase (Day 0-7)

    RICE Protocol:

  • Rest from aggravating activities
  • Ice: 15-20 min, several times daily
  • Compression: Elastic bandage
  • Elevation: When possible
  • Gentle Movement:

  • Pain-free walking
  • Avoid stretching
  • Avoid crossing legs
  • Subacute Phase (Week 1-3)

    Isometric Adduction

  • Ball or pillow between knees
  • Squeeze gently
  • Hold 5-10 seconds
  • 3 x 10
  • Supine Adduction (Sliding)

  • Lie on back
  • Slide injured leg out and in
  • Pain-free range only
  • 3 x 15
  • Bridges

  • Ball between knees
  • Squeeze while bridging
  • 3 x 15
  • Strengthening Phase (Week 3-8)

    Side-Lying Adduction

  • Lie on injured side
  • Lift bottom leg toward ceiling
  • 3 x 15
  • Copenhagen Adduction (Modified)

  • Side plank, top foot on bench
  • Bottom leg hangs or supports
  • Progress to full Copenhagen
  • 3 x 8-10 each side
  • Sumo Squats

  • Wide stance, toes out
  • Squat down, feeling inner thighs
  • 3 x 12
  • Lateral Lunges

  • Step to side
  • Keep other leg straight
  • 3 x 10 each side
  • Cable/Band Adduction

  • Standing, pull leg across body
  • 3 x 15 each side
  • Return to Sport Phase (Week 6-12)

    Agility Progression:

    1. Jogging straight

    2. Gentle curves

    3. Wide cutting

    4. Sharp cutting

    5. Sport-specific drills

    Kicking Progression (If Applicable):

    1. Gentle passing

    2. Increased power

    3. Full power

    The Copenhagen Adduction Exercise

    Research shows Copenhagen exercises significantly reduce groin injury risk.

    Progression:

    1. Short lever (knee on bench): Easier

    2. Long lever (foot on bench): Harder

    3. Dynamic (lower and lift): Hardest

    Protocol:

  • Build to 3 x 10-15 each side
  • Include in regular training
  • Sample Program

    Week 1-2

    Daily:

    1. Ice: 3-4 times

    2. Gentle walking

    3. Isometric adduction: 3 x 10 (when pain allows)

    Week 3-4

    Daily:

    1. Side-lying adduction: 3 x 15

    2. Bridges with squeeze: 3 x 15

    3. Sliding adduction: 3 x 15

    3x Weekly:

    4. Sumo squats: 3 x 12

    Week 5-8

    3x Weekly:

    1. Copenhagen (modified): 3 x 8 each

    2. Lateral lunges: 3 x 10 each

    3. Cable adduction: 3 x 15 each

    4. Single leg RDL: 3 x 8 each

    Week 8+

  • Continue strengthening 2x weekly
  • Progressive running/cutting
  • Sport-specific drills
  • Hip Strengthening (Essential)

    Groin injuries often involve hip weakness. Include:

    Glute Work:

  • Bridges → Single leg bridges
  • Clamshells
  • Hip thrusts
  • Hip Flexor Work:

  • Standing hip flexion
  • Mountain climbers (when ready)
  • Core Work:

  • Planks
  • Side planks
  • Dead bugs
  • Stretching Considerations

    Acute Phase

    Don't stretch. Can worsen injury.

    Later Phases

    Gentle stretching when pain-free:

  • Butterfly stretch (gentle)
  • Frog stretch (careful)
  • 20-30 seconds, no forcing
  • Focus remains on strength, not flexibility.

    Prevention

    Copenhagen Protocol

    Research shows including Copenhagen exercises in training reduces groin injuries by up to 41%.

    Recommendation:

  • 2-3 times per week
  • As part of regular training
  • Continue indefinitely
  • Other Prevention Measures

  • Adequate warm-up
  • Progressive training loads
  • Strong adductors AND abductors
  • Good hip mobility
  • Core stability
  • Common Mistakes

    1. Stretching Too Early

    Problem: Delays healing

    Fix: Wait until pain-free

    2. Returning Too Soon

    Problem: Re-injury (very common)

    Fix: Complete full rehab

    3. Ignoring Hip Strength

    Problem: Imbalances persist

    Fix: Comprehensive hip strengthening

    4. Skipping Copenhagen Exercises

    Problem: Missing proven prevention

    Fix: Make them routine

    Recovery Timeline

  • **Grade 1:** 1-2 weeks
  • **Grade 2:** 4-8 weeks
  • **Grade 3:** 3+ months
  • When to See a Doctor

  • Severe pain
  • Significant bruising
  • Unable to walk
  • Pain with coughing/sneezing (may indicate hernia)
  • No improvement after 2 weeks
  • The Bottom Line

    Groin strains require:

    1. Early protection — Don't stretch acutely

    2. Progressive adductor strengthening — Key to recovery

    3. Copenhagen exercises — Proven prevention

    4. Hip strengthening — Address the whole chain

    5. Patient return — Re-injury is common

    Copenhagen exercises should be routine for any athlete at risk.
