Hip weakness is one of the most common and most consequential physical limitations in both active and sedentary populations. It contributes to knee pain, lower back pain, ankle instability, poor squat mechanics, reduced athletic performance, and increased fall risk in older adults. Yet most people who have it do not know it, because hip weakness rarely announces itself as hip pain. It shows up as problems elsewhere.
The challenge with addressing hip weakness is that the hip is not a single muscle. It is a complex of more than 20 muscles working together, and weakness in different parts of the hip complex causes different problems and requires different exercises. Understanding which muscles are most commonly weak and why they matter makes the difference between a programme that works and one that does not.
The Three Most Commonly Weak Hip Muscle Groups
Gluteus medius and minimus: The hip abductors on the outer side of the hip are the most commonly weak muscles in the hip complex and the ones most frequently linked to knee pain, IT band syndrome, lower back pain, and poor running mechanics. The gluteus medius is responsible for stabilising the pelvis during single-leg activities. When it is weak, the hip drops on the unsupported side during walking and running, a pattern known as the Trendelenburg gait, which sends a wave of compensatory stress through the knee, ankle, and lower back.
Gluteus maximus: The largest muscle in the body and the primary hip extensor. Gluteus maximus weakness is extremely common in people who sit for long periods because prolonged hip flexion causes reciprocal inhibition, where the nervous system reduces the activation of the glutes while the hip flexors are shortened. Weak glutes shift the load of hip extension activities like walking, climbing stairs, and deadlifting to the lower back and hamstrings.
Hip external rotators: A group of six deep muscles that rotate the hip outward. These muscles also contribute to hip stability during single-leg activities. Weakness here causes the femur to rotate inward during movement, which is the mechanism behind the knee cave that occurs during squatting and running and is directly associated with patellofemoral pain syndrome and ACL injury risk.
Why Hip Weakness Develops
Prolonged sitting: Sitting keeps the glutes in a lengthened, inactive position. Over time the nervous system reduces its recruitment of the glutes during movement, a phenomenon sometimes called gluteal amnesia. The hip flexors, which are shortened during sitting, become dominant and the glutes become progressively less active.
Sedentary lifestyle: The glutes and hip abductors are primarily challenged by single-leg activities, lateral movement, and loaded hip extension. A lifestyle that involves mostly walking and sitting does not sufficiently challenge these muscles to maintain their strength.
Previous injury: Lower limb injuries, including ankle sprains, knee injuries, and lower back problems, frequently result in altered movement patterns that reduce hip muscle activation long after the original injury has healed.
Postpartum changes: Pregnancy and childbirth alter pelvic mechanics and can reduce hip muscle activation, particularly in the gluteus medius and pelvic floor complex. Hip weakness is extremely common postpartum and is a significant contributor to the lower back and pelvic girdle pain that many women experience after childbirth.
How to Identify Hip Weakness
Single-leg squat test: Stand on one leg and slowly lower into a single-leg squat to approximately 45 degrees. Watch in a mirror or have someone observe from the front. If the knee dives inward significantly, the hip drops on the unsupported side, or you struggle to control the descent, gluteus medius and hip external rotator weakness is present.
Hip drop observation: Walk slowly in front of a mirror and observe whether one hip drops noticeably lower than the other with each step. A visible hip drop indicates gluteus medius weakness on the standing leg side.
Glute bridge test: Perform a glute bridge and hold the top position for 10 seconds. If you feel the effort primarily in your hamstrings or lower back rather than your glutes, gluteus maximus activation is poor and weakness is likely.
Standing on one leg: Stand on one leg for 30 seconds. Significant wobbling, hip drop, or inability to maintain the position suggests hip abductor weakness and overall hip stability deficits.
Exercises for Weak Hips
Phase 1: Activation Exercises
These exercises are performed first to re-establish the neuromuscular connection with the weak hip muscles before loading them. They are particularly important for people with significant hip weakness or those returning from injury.
Clamshell
Target muscles: Gluteus medius and hip external rotators.
How to do it:
- Lie on your side with hips stacked, knees bent to 45 degrees
- Keep your feet together and rotate the top knee upward against gravity
- Pause for one second at the top
- Lower slowly over 2 to 3 seconds
- Complete 2 sets of 15 reps per side
Key cue: The pelvis must not rotate backward as the knee rises. Place your top hand on your hip to monitor for this. If the pelvis rolls, reduce the range of the knee lift until stability improves.
Progression: Add a light resistance band above the knees once bodyweight feels easy.
Glute Bridge
Target muscles: Gluteus maximus primarily, gluteus medius as a stabiliser.
How to do it:
- Lie on your back with knees bent, feet flat on the floor hip-width apart
- Press both feet into the floor and lift the hips until the body forms a straight line from knees to shoulders
- Squeeze the glutes firmly at the top
- Hold for 2 seconds, then lower slowly
- Complete 3 sets of 15 reps
Key cue: The movement should be felt in the glutes, not the lower back or hamstrings. If you feel it mainly in the hamstrings, move the feet slightly closer to the body. If you feel it in the lower back, reduce the height of the bridge and focus on squeezing the glutes before lifting.
Lying Hip Abduction
Target muscles: Gluteus medius and minimus.
How to do it:
- Lie on your side with legs straight and hips stacked
- Lift the top leg to approximately 45 degrees
- Pause at the top for one second
- Lower slowly over 2 to 3 seconds
- Complete 2 sets of 15 reps per side
Key cue: The foot should point slightly downward rather than toward the ceiling. This internal rotation of the hip during abduction maximises gluteus medius activation and reduces TFL involvement.
Phase 2: Foundational Strengthening Exercises
Once activation is established, these exercises build meaningful strength in the hip complex.
Single Leg Glute Bridge
Target muscles: Gluteus maximus and gluteus medius as a pelvic stabiliser.
How to do it:
- Lie on your back with knees bent, feet flat on the floor
- Extend one leg straight
- Press the supporting foot into the floor and lift the hips
- Keep the hips level throughout, do not allow the extended leg side to drop
- Hold for 2 seconds at the top
- Complete 3 sets of 10 reps per side
Key cue: The hips staying level is the most important technical point. If one hip drops significantly, return to the bilateral glute bridge until strength improves.
Lateral Band Walk
Target muscles: Gluteus medius and minimus throughout the full abduction range during walking.
How to do it:
- Place a resistance band just above the knees
- Stand with feet hip-width apart and a slight bend in the knees
- Step sideways to the right with the right foot, then bring the left foot to meet it
- Take 10 to 15 steps to the right, then 10 to 15 steps to the left
- Keep the band taut throughout and do not allow the knees to cave inward
- Complete 3 sets in each direction
Key cue: Maintain a slight forward lean and keep the knees tracking over the toes. The steps should be wide enough to keep the band under tension the entire time.
Hip Thrust
Target muscles: Gluteus maximus with greater range of motion than the glute bridge.
How to do it:
- Sit on the floor with your upper back against a bench or sofa
- Bend the knees with feet flat on the floor hip-width apart
- Drive the hips upward until the body forms a straight line from knees to shoulders
- Squeeze the glutes firmly at the top
- Hold for one second, then lower slowly
- Complete 3 sets of 12 reps
Progression: Add a resistance band above the knees or hold a weight on the hips to increase the load as strength improves.
Banded Clamshell
Target muscles: Gluteus medius and hip external rotators with added resistance.
How to do it:
- Lie on your side with a resistance band just above the knees, knees bent to 45 degrees
- Keep feet together and rotate the top knee upward against the band
- Pause for one second at the top
- Lower slowly over 2 to 3 seconds
- Complete 3 sets of 15 per side
Key cue: Choose a band resistance that makes the last 3 reps of each set genuinely challenging without causing the pelvis to rotate.
Step Ups
Target muscles: Gluteus maximus, gluteus medius as a stabiliser, quadriceps.
How to do it:
- Stand facing a step or box of 30 to 40 centimetres
- Place one foot fully on the step
- Drive through the heel to step up, bringing the other knee forward to hip height
- Lower slowly and with control
- Complete 3 sets of 10 reps per leg
Key cue: The trailing leg should contribute nothing to the movement. All effort comes from the working leg on the step. This single-leg demand directly challenges the gluteus medius as a pelvic stabiliser.
Phase 3: Loaded and Functional Strengthening
Once foundational strength is established, these exercises load the hip complex through functional movement patterns.
Romanian Deadlift
Target muscles: Gluteus maximus and hamstrings through hip extension under load.
How to do it:
- Stand with feet hip-width apart, holding dumbbells in front of the thighs
- Push the hips backward, letting the torso lean forward naturally
- Keep the dumbbells close to the legs and maintain a neutral spine
- Lower until a strong hamstring stretch is felt
- Drive the hips forward to return to standing
- Complete 3 sets of 8 to 10 reps
Key cue: The movement is a hip push backward, not a bend forward. Keep the knees slightly bent but do not let them drive forward as in a squat.
Bulgarian Split Squat
Target muscles: Gluteus maximus, gluteus medius as a stabiliser, quadriceps.
How to do it:
- Stand facing away from a bench or sofa with one foot elevated behind you
- Lower the body by bending the front knee until the rear knee approaches the floor
- Drive through the front heel to return to standing
- Complete 3 sets of 8 reps per leg
Key cue: The front knee should track over the second and third toes throughout. If it caves inward, the gluteus medius and hip external rotators need more activation work before progressing to this exercise.
Lateral Lunge
Target muscles: Gluteus medius and adductors in a lateral movement pattern that most exercises miss.
How to do it:
- Stand with feet together
- Step one foot wide to the side and lower the hips toward the stepping foot, bending the knee
- Keep the other leg straight
- Drive through the bent leg to return to standing
- Complete 3 sets of 10 reps per side
Key cue: The stepping knee should track over the toes and the torso should remain upright rather than leaning forward excessively.

Frequently Asked Questions
How long does it take to strengthen weak hips? Most people notice meaningful improvement in hip stability and strength within 4 to 6 weeks of consistent training 3 times per week. Full resolution of the weakness and the associated pain or movement problems typically takes 8 to 12 weeks of progressive training.
Can weak hips cause knee pain? Yes, directly. Gluteus medius weakness allows the femur to rotate inward during movement, increasing the stress on the medial and lateral structures of the knee. Strengthening the hip abductors and external rotators is one of the most effective evidence-based treatments for patellofemoral pain syndrome and IT band-related knee pain.
Should I stretch or strengthen weak hips? Both, but in the right order. If the hip muscles are both tight and weak, which is common, begin with gentle release and stretching to restore range of motion, then progress to strengthening. Building strength through a limited range produces limited functional results. Once adequate range is available, strengthening becomes more productive.
Can I do these exercises every day? The activation exercises from Phase 1 can be performed daily without recovery concerns. The loaded exercises from Phases 2 and 3 require 48 hours of recovery between sessions. Three sessions per week is the appropriate frequency for strength development.
Is hip weakness the same as hip instability? Related but not identical. Hip weakness refers to reduced force production capacity in the hip muscles. Hip instability refers to the inability to control the position of the hip and pelvis during movement. Weakness frequently causes instability, and strengthening the hip muscles usually improves both.
