Hip Flexor Strain Exercises: Recovery for Pulled Hip Flexor

A hip flexor strain can sideline runners, soccer players, martial artists, and anyone whose activities involve powerful hip flexion. The hip flexors—particularly the iliopsoas—are critical for lifting your leg, and a strain here affects walking, running, and even sitting. Here's how to rehabilitate properly.

Understanding Hip Flexor Strains

The hip flexors are a group of muscles that flex the hip (bring the thigh toward the torso):

• Iliopsoas: Main hip flexor (iliacus + psoas major)
• Rectus femoris: Quad muscle that also flexes hip
• Sartorius: Assists with flexion
• TFL: Assists with flexion

Common causes:

• Sprinting (especially acceleration)
• Kicking (soccer, martial arts)
• Sudden movements
• Overuse in runners
• Tight hip flexors + sudden loading

Strain grades:

• Grade 1: Mild strain. 1-3 weeks recovery.
• Grade 2: Moderate tear. 3-6 weeks recovery.
• Grade 3: Severe tear. 8-12+ weeks recovery.

Symptoms:

• Pain at front of hip/groin
• Pain lifting leg (stairs, getting in car)
• Pain with walking or running
• Tenderness deep in front of hip
• Weakness in hip flexion
• May feel a "catch" or tightness

Phase 1: Acute Management (Days 1-5)

Protection

First 48-72 hours:

• Rest from aggravating activities
• Ice 15-20 minutes every few hours
• Avoid stretching aggressively (can worsen tear)
• May need crutches for severe strains

What to avoid:

• Running or jogging
• High knee activities
• Kicking
• Aggressive hip flexor stretching
• Stairs (minimize)

Gentle Movement

Gentle hip flexion (lying):

1. Lie on back
2. Slide heel toward buttocks (knee bends)
3. Gently lift bent knee toward chest
4. Small, pain-free movement
5. 10-15 repetitions

Prone lying:

1. Lie face down
2. Stretches hip flexors gently
3. Hold 2-5 minutes
4. Several times daily

Walking:

• Short distances
• Slow pace
• Shorter strides
• May need crutches if painful

Phase 2: Early Recovery (Days 5-14)

Active Range of Motion

Supine hip flexion:

1. Lie on back
2. Lift leg with knee bent
3. Lower slowly
4. 15-20 repetitions

Standing hip flexion:

1. Hold wall for support
2. Lift knee toward chest
3. Control movement
4. 15 repetitions each leg

Marching in place:

1. Gentle marching
2. Lower leg lift initially
3. Progress height as tolerated
4. 30 seconds to 1 minute

Gentle Stretching

Modified hip flexor stretch:

1. Half-kneeling position
2. Keep torso upright
3. Gently tuck pelvis under (posterior tilt)
4. Should feel mild stretch only
5. Hold 20-30 seconds
6. Don't push into pain

Prone hip extension:

1. Lie face down
2. Gently lift one leg straight up
3. Small movement
4. 10 repetitions each leg

Isometric Exercises

Isometric hip flexion:

1. Lie on back, knee bent
2. Place hand above knee
3. Press knee into hand (don't move)
4. Hold 5-10 seconds
5. 10-15 repetitions
6. 25-50% effort

Phase 3: Strengthening (Weeks 2-4)

Progressive Hip Flexor Strengthening

Straight leg raises:

1. Lie on back
2. Keep leg straight
3. Lift to 45 degrees
4. Lower slowly
5. 15 repetitions, 2-3 sets
6. Add ankle weight to progress

Standing hip flexion with band:

1. Band around ankles
2. Lift knee against resistance
3. Control return
4. 15 repetitions each leg

Seated hip flexion:

1. Sit on edge of chair
2. Lift knee toward chest
3. Add weight on thigh for resistance
4. 15 repetitions

Core and Hip Strengthening

Dead bugs:

1. Lie on back, arms up, knees bent
2. Lower opposite arm and leg
3. Hip flexors work to control movement
4. 10-12 each side

Glute bridges:

1. Lie on back, knees bent
2. Lift hips off ground
3. Hip extends (opposite of flexion)
4. 15 repetitions

Bird dogs:

1. On hands and knees
2. Extend opposite arm and leg
3. 10-12 each side

Eccentric Strengthening

Eccentric hip flexor lowering:

1. Stand holding wall
2. Lift knee high
3. Lower leg slowly (3-4 seconds)
4. 10 repetitions each leg

Phase 4: Return to Running (Weeks 4-8)

Running Readiness

Before running, you should:

• Walk normally without pain
• Climb stairs without pain
• Single-leg hip flexion against resistance pain-free
• Pass hop test pain-free

Running Progression

Week 1:

• Walk 5 min, jog 1 min × 5-6
• Flat surface, easy pace
• Short strides

Week 2:

• Walk 2 min, jog 3 min × 5
• Monitor for symptoms

Week 3:

• Walk 1 min, jog 4 min × 5
• Progress to continuous jog

Week 4:

• Continuous jog 20-30 min
• Add tempo variations

Week 5+:

• Add striders
• Progress to sprinting gradually
• Sport-specific drills

Sprinting Return

Progression:

1. 50% speed × several repetitions
2. 60% speed
3. 70% speed
4. 80% speed
5. 90% speed
6. Full speed (only when 90% is pain-free)

Kicking Return (If Applicable)

1. Gentle passing
2. Progress distance
3. Progress power
4. Full kicking last

Stretching Routine

Daily Stretches (Once Acute Phase Passes)

Half-kneeling hip flexor stretch:

1. Back knee down, front foot flat
2. Tuck pelvis under
3. Lean forward slightly
4. Hold 30-45 seconds each side

Couch stretch:

1. Kneel with back foot against wall/couch
2. Front foot flat in front
3. Tuck pelvis, stay upright
4. Hold 30-60 seconds each side

Supine hip flexor stretch:

1. Lie on edge of bed
2. Pull one knee to chest
3. Let other leg hang off bed
4. Hold 30 seconds each side

Dynamic Stretches (Pre-Activity)

1. Leg swings front to back
2. Walking lunges
3. High knees (controlled)
4. A-skips

Sample Rehabilitation Program

Phase 2 (Days 5-14)

Daily:

• ROM exercises: 15-20 reps each
• Modified stretching: 30 seconds
• Isometrics: 2 × 10

Phase 3 (Weeks 2-4)

3x weekly:

• Straight leg raises: 3 × 15
• Standing hip flexion with band: 3 × 15
• Dead bugs: 2 × 12
• Glute bridges: 2 × 15

Daily:

• Full stretching routine

Phase 4 (Weeks 4-8)

Running program: Per protocol above

2x weekly:

• Maintenance strengthening
• Sport-specific training

Preventing Re-Injury

Hip flexor strains recur frequently:

1. Maintain flexibility - Daily hip flexor stretching
2. Strengthen hip flexors - Regular strengthening exercises
3. Warm up properly - Dynamic stretching before activity
4. Address weakness - Strong hip flexors resist strain
5. Progress training gradually - Avoid sudden increases in sprinting
6. Don't ignore tightness - Tight muscles are vulnerable muscles
7. Core strength - Supports hip function

When to Seek Help

See a doctor if:

• Severe pain or significant weakness
• Suspected complete tear
• No improvement after 2-3 weeks
• Groin swelling or mass
• Pain radiating into thigh
• Difficulty walking

The Bottom Line

Hip flexor strain recovery requires progressive loading:

1. Protect early - Avoid stretching and running
2. Restore range of motion - Before strengthening
3. Strengthen progressively - SLR → banded work → dynamic
4. Return to running gradually - Walk-jog before sprinting
5. Maintain flexibility - Prevent recurrence

The hip flexors are essential for running and kicking. Take the time to rehabilitate properly—rushing back leads to re-injury. With consistent work, you'll return to full speed stronger and more resilient.
