Many people experience popping in their hips. Most patients come to the clinic complaining of back or knee pain, and a popping hip may be a secondary complaint. Although typically not a significant pain generator, popping in the hip is a sign of an underlying dysfunction in the hip needing to be addressed. If the popping in the hip is not attended to, more serious orthopedic issues may arise down the road.
There are three main causes of a popping hip – external, internal, and intra-articular. External is most frequent and refers to the iliotibial (IT) band snapping over the greater trochanter of the femur. Internal is also common and refers to the iliopsoas (hip flexor) tendon snapping over a bony prominence on the pelvis or at the lesser trochanter of the femur. Intra-articular is least common and refers to a floating loose body within the joint such as a torn labrum. External and internal variations are often due to gradual onset, whereas an intra-articular loose body is often due to trauma. There is a higher incidence of hip popping in females, especially those who perform sports requiring repetitive flexion and extension of the hip such as gymnastics, dance, soccer, and running.
How to fix it
Popping in the hip is often related to a stability issue in the hip or the core. To address this, work to improve your hip stability in all three planes of motion. Train slowly, controlling the motion to avoid the pop. Train only through ranges of motion where you can avoid the pop, and gradually increase the range of motion as your stability improves. The external hip pop (ITB over greater trochanter) is often related to poor hip stability in the frontal plane (abduction/adduction), and increasing strength of muscles such as the gluteus medius will be helpful in decreasing the external hip pop. The internal hip pop relates to the iliopsoas muscle. The iliopsoas muscle has shared attachments with the diaphragm. If the diaphragm is not providing a solid anchor point for the iliopsoas muscle, function of the hip flexor will be impaired increasing the likelihood of an internal hip pop. For this, focus working on diaphragmatic breathing to create better stability patterns in your core. Intra-articular hip popping requires an in-depth examination to determine which structures may be injured and to determine the best course of care.
To know exactly which exercises and treatments are best for you, it is important to seek out a therapist who understands hip biomechanics and can help you address the specific stability limitations causing the pop. Whatever the cause, popping in the hip should not be ignored. Even if caused by mild muscle imbalance, a popping hip can worsen over time if not addressed early.

Core Exercises – Do’s and Don’ts
Many patients understand they need to strengthen their core in order to live functional and pain free lives. However, most do not know where to start. The popular opinion is exercises such as sit-ups, crunches, bicycle crunches, and Russian twists are the primary exercises to improve core strength. Unfortunately, these commonly performed exercises are not the best choice when looking to add strength and functionality to your core.
The Problem with Sit-ups and Crunches
Sit-ups and crunches are perhaps the most regularly performed core exercises. These exercises are effective at increasing the tone of the six-pack or rectus abdominis muscle group. While great for aesthetics, a tight and toned six-pack is not essential for a functional core and may even be detrimental. The issue with sit-ups and crunches are the forces placed on the spine during these exercises. Both involve repetitive flexion of the lumbar spine and most of modern society already gets too much ‘lumbar flexion.’ Lumbar flexion means rounding forward of the low back. The low back is in flexion when we are sitting in our car, at work, or on the toilet. The low back is flexed when we pick items up from the floor with improper form. The net result of so much lumbar flexion is placing undue stress on the discs, muscles, ligaments, and nerves of the low back. Sit-ups and crunches involve repetitive flexion of the low back and thus add fuel to the ‘flexion fire’ we get all throughout the day.
The Problem with Rotational Core Exercises and Stretching
The Russian twist and bicycle crunches are other commonly performed core exercises that are not ideal for the function of the core or spine. The Russian twist is performed by balancing on your pelvis with legs suspended in the air and knees bent while the upper body is held at roughly a 45 degree angle. Next, the athlete uses their hands or a medicine ball to twist back and forth in an attempt to work the abdominal obliques. Bicycle crunches are similar except the individual is on their back and the rotational crunch is combined with a straightening of the opposite leg and hip. The first problem with the Russian twist is it is extremely difficult to keep the spine in a neutral position and many individuals round their backs due to a lack of core strength and balance. Once again, many people are developing a detrimental position of lumbar flexion during this exercise.
Another issue with the Russian twist and bicycle crunch is the forced rotational load it places on the spine. Functional movement specialists now agree the main purpose of the core is to resist forces placed against the spine rather than actually creating movement. The lumbar spine only rotates 2-3 degrees per segment and thus requires more stability in the rotational (transverse) plane compared to mobility. I’ll explain exercises such as the Pallof Press and Cross Press in a future blog post, as both are excellent exercises for improving core stability in the rotational plane.
Basics of Effectively Performing a Core Exercise
Before we get into the specific exercises I teach my patients, I’ll explain why form is important for any core exercise you perform. First, the spine needs to be in a neutral position. A neutral spine may look different for each person, but the spine should be straight and may have a slight extension curvature. Extension is the opposite of a flexed and rounded position of the spine. The two variables that affect proper neutral spine positioning are your rib positioning and your pelvic posture. Many patients have what is called ‘flared ribs’. This means your ribs are protruding upwards and forwards and may even be visible. When the ribs are in this position the diaphragm muscle cannot function properly and core strength will suffer. Use an exhale breath to push your ribs downwards towards the floor to place them in a more ideal position.
Secondly, you need to be aware of the position of your pelvis. Think about your pelvis as a fish bowl filled with water. If you have what we call an ‘anterior pelvic tilt’ your pelvis is dumped forward and water will be spilling out of the metaphorical fish bowl. Less commonly, patients may adopt a ‘posterior pelvic tilt’ where the water will be spilling backwards. Both of these pelvic postures are detrimental to neutral spine positioning, as well as core strength. Always think about keeping your pelvis tucked under you so water cannot spill out of the fish bowl. By making sure your ribs and pelvis work together to maintain a neutral spine, you will safely perform core exercises.
Practice these Core Exercises:
3 Position Plank
The 3 position plank is a sequential exercise involving a front plank, right side plank, and left side plank. Each position is held for 10 seconds before switching positions. Do your best to avoid dropping to the ground when switching positions. Switching positions every 10 seconds forces the brain and nervous system to react to a new stability pattern frequently and is thus more typical of how we move in life and sports. Additionally, by switching positions every 10 seconds we better guarantee perfectly executed reps.
The dead bug is another excellent option for building your core strength. Lay on your back with your hips, legs, and arms raised. Simply holding this position is a difficult exercise in itself and is an effective way to exercise your core. Make the movement more dynamic by reaching one arm over your head and slowly lowering the opposite heel towards the ground. Alternate sides, and perform in succession while making sure to keep your ribs down, low back glued to the ground, and head supported and slightly elevated to protect your neck.
The bird dog exercise teaches you to move your extremities while maintaining a neutral spine. The exercise does an excellent job of mimicking real athletic activities you will face in daily life. Get in a tabletop position with your hands stacked under your shoulders and your knees stacked under your hips. Your chin should be tucked and the back of your neck long with no creasing of the skin. Slowly move one of your arms forward while simultaneously extending the opposite leg backwards. The back leg only needs to be about 2 inches off of the ground to avoid hyper-extending your low back. Hold the completely extended position for a count of 2 and then return to neutral. Alternate sides while keeping a neutral spine and make sure to not let your pelvis rotate and shift excessively. Imagine there is a glass of water resting on the base of your low back and you do not want to let it spill!
My goal with this blog post is to provide you with safe and effective exercises for improving the strength and function of your core. Enjoy!

Train like a pro
Elite athletes understand they need to build durable and resilient muscles, joints, ligaments, and tendons. The best way to do this, aside from a healthy diet (nutrition blog post) and adequate recovery practices (sleep blog post), is resistance weight training. When we lift weights, we place an external load on the body, mimicking the forces encountered in sports. Forces placed against the body are present in both contact and non-contact sports. When participating in non-contact sports such as running, throwing, and golf, forces are still exerted from contact with the ground or from internal forces the body places on itself during movement. This week we will dive into the key principles of strength and conditioning that will help you train like a pro.
Keep it simple
Most people would be surprised by the simplistic workouts of the world’s top athletes. There is a misconception professional athletes are using state of the art equipment unavailable to the average person. While elite athletes do have access to incredible facilities and equipment, most pros are still using simple squat racks, barbells, dumbbells, pull-up bars, and kettlebells – equipment we almost all have access to.
Traditional bodybuilding training focuses on single joint, single muscle group exercises. While effective for improving aesthetics, these movements do not increase functionality in the athlete or mimic the demands encountered in sports. The key is to focus on compound, multi-joint exercises like the deadlift, squat, pull-up, bench press, and weighted rows. These exercises will stress multiple muscle groups, requiring they work together to move the load.
Focus on closed chain exercises
Closed chain exercises are when the body part being moved is anchored to the ground or an immovable object, like a pull-up bar. The direction of muscle pull is towards the ground or immovable object. Force is being transmitted through the ground, not through the air when you perform exercises such as deadlifts, squats, push-ups, pull-ups, or lunges. These exercises recruit larger muscle groups and require they work together to move the load. Closed chain exercises also require greater stabilization of the spine, which is essential for protecting the lower back during sports.
Contrarily, open chain exercises are when the arm or foot is free to move and is not anchored to the ground or an immovable object. The direction of muscle pull is inwards toward the body when you perform exercises such as bicep curls, bench press, hamstring leg curls, or quad knee extensions. The muscle is mainly recruited in the concentric (shortening) phase of muscle action. As such, open chain exercises are less functional to the athlete and should not be the focus of a strength and conditioning program.
Control the eccentric portion of the lift
Many injuries in sports occur when the muscle is asked to contract while it is in the process of lengthening. Bicep tendon tears, hamstring tears, and achilles ruptures are common injuries that often occur in the eccentric phase of muscle action. This type of contraction causes the most tearing of muscle fibers, whether injury occurs or not. A simple example of eccentric muscle action is during the bicep curl. As the weight is lifted, the bicep is acting concentrically, meaning it is shortening while it is contracting. As you slowly lower the weight, the bicep is eccentrically contracting, meaning you are putting it under load as the muscle lengthens.
By focusing on slow lowering in movements like the squat (descent), deadlift (lowering the bar to the ground), and pull-up, you can target the eccentric muscle actions, making your body more durable and resilient to injury. As an added bonus, muscle growth is stimulated most by eccentric exercises.
Adopt a pull to push ratio of 2:1 or 3:1
This ratio will maintain the balance of your posterior (back) and anterior (front) muscle chains. Proper balance and upright posture depends on balance between these two chains of muscles. Most people are insufficient in their posterior chain (calves, hamstrings, glutes, triceps, upper back muscles) and overly sufficient in their anterior chain (quads, upper abdominals, pecs, and biceps). A reason for this pattern is the anterior chain muscles are the ones typically associated with an aesthetic body and are trained more often than the posterior chain muscles. When it comes to function, a strong posterior chain in balance with the anterior chain is key. A strong posterior chain will help you develop more force in your running stride, take and receive hits in contact sports, and stick a landing after a vault in gymnastics.
Pulling exercises include pull-ups, deadlifts, seated rows, dumbbell rows, and lat-pull downs.
Pushing exercises include push-ups, bench press, incline DB press, landmine press, and strict press.
Finally, it is important your gym training closely mimics demands encountered by your sport. The Specific Adaptation to Imposed Demands (SAID) principle states the biomechanical and neural adaptations your body makes to training will be specific to the movements being trained. For example, if you want to get better at running, you should not bench press every time you go to the gym. Conversely, if you are an offensive lineman in football, obtaining a strong bench press will be essential to success in your sport. Choosing exercises that either recruit the muscle groups you plan to use or movements that look similar to the ones you perform in your sport is crucial to training like a pro.
