Why Hip Flexor Strength Matters

Your hip flexors — primarily the iliopsoas, rectus femoris, and sartorius — are responsible for lifting the thigh toward the torso, a movement essential for walking, running, climbing stairs, and getting up from a seat. When these muscles are weak or inhibited (a common result of prolonged sitting), you may notice lower back tightness, anterior pelvic tilt, hip pain, or a reduction in stride length during exercise.

Physiotherapists frequently target hip flexor strengthening as part of rehabilitation for lower back pain, hip impingement, and even knee conditions, because the hip complex plays a central role in whole-body mechanics.

Before You Begin

If you have a current hip, groin, or lower back injury, consult a physiotherapist before starting these exercises. Some movements may need to be modified or avoided depending on your specific condition.

The 6 Exercises

1. Supine Hip Flexion (Lying Leg Raise)

Lie on your back with one knee bent and one leg straight. Keeping your core engaged and lower back flat, slowly raise the straight leg to about 45°, hold for 2 seconds, then lower with control. Sets/reps: 3 × 10–15 per side.

2. Standing Marching

Stand tall holding a wall or chair for balance. Drive one knee upward to hip height, lower with control, then repeat on the other side. Focus on a smooth, controlled movement — don't let the pelvis tilt. Sets/reps: 3 × 12–15 per side.

3. Seated Knee Raise (with Resistance Band)

Sit upright on a chair with a resistance band looped just above the knees. Press one knee upward against the band's resistance, hold briefly, then lower slowly. This is an excellent low-impact option for beginners or those with back sensitivity. Sets/reps: 3 × 12 per side.

4. Mountain Climber (Slow, Controlled)

Begin in a high plank position. Drive one knee toward your chest, pause, return, then switch sides. Performing this slowly (rather than as a cardio drill) turns it into a genuine hip flexor strengthening exercise with added core demand. Sets/reps: 3 × 8–10 per side.

5. Step-Up with High Knee

Using a step or box, step up with one foot and drive the opposite knee high as you rise. This mimics functional movement patterns and challenges the hip flexors through a full range. Sets/reps: 3 × 10 per side.

6. Psoas March (Dead Bug Variation)

Lie on your back, bring both knees to a 90° tabletop position. Slowly lower one heel toward the floor while the other stays raised, then alternate. Keep the lower back pressed gently into the floor throughout. Sets/reps: 3 × 10 per side.

Programming Tips

  • Perform hip flexor strengthening 2–3 times per week, with at least one rest day between sessions.
  • Always warm up with 5 minutes of light movement (walking, cycling) beforehand.
  • Pair these exercises with hip flexor stretching on alternate days to maintain a balance between strength and flexibility.
  • Progress gradually — add resistance or reps only when you can complete current sets with full control and no pain.

Signs You Need Professional Input

If you notice groin pain, sharp hip clicking with pain, or lower back discomfort during any of these exercises, stop and book an assessment with a physiotherapist. These symptoms can indicate underlying conditions such as hip impingement, labral pathology, or lumbar instability that require tailored management.

The Bottom Line

Strong hip flexors are foundational to good posture, pain-free movement, and athletic performance. These six exercises provide a progressive, evidence-informed approach to building that strength — and they can be done at home with minimal equipment.
