The hip is a very stable ball and socket type joint with an inherently large range of motion. The hip contains some of the largest muscle in the body as well as some of the smallest. Most people lack mobility due to a relatively sedentary lifestyle. Periods of prolonged sitting results in tightness of the hip flexors and hamstrings. Tightness in the muscles and ligaments can created joint forces that result in arthritis, postural problems, bursitis, and mechanical back pain.
The gluteus medius is a muscle that sits on the outside of the hip area. This muscle is used for standing upright and walking. When injured, these muscles will cause a limp. If these muscles are torn, it can cause severe pain when walking, sitting, or sleeping. Treatment usually involves rest, physical therapy, and sometimes surgery to repair the torn muscle, if no other treatments bring relief from pain.
Why does it tighten down so much when overworking as a spinal stabilizer? Remember that length tension relationship we talked about? Well, if the psoas is tight, it can compress the spine easier, thus providing spinal stability. Plus, it has to work a lot to stabilize the spine. When you don’t have correct functioning of the diaphragm and abdominals, the psoas holds a great deal of tension to do the job. This tightness or tension makes it a very ineffective hip flexor.
Note: Exercises that strengthen the hip flexors also involve contracting (shortening) these muscles. So if tight hip flexors are a problem for you, it might be wise to limit how many direct hip-strengthening exercises you perform. These exercises are more geared toward people who have been told they have weak hip flexors that need strengthening or are looking for targeted exercises to build more power and stamina in the hip flexors.
Stand with your feet hip-width apart, knees slightly bent, and hands on hips. Brace your core—imagine you’re about to get punched in the stomach. Without changing the position of your knees, bend at your hips and lower your torso until it’s almost parallel to the floor (or as far as you can comfortably go without rounding your back). Pause, then lift your torso back to the starting position. Be sure to squeeze your glutes and push your hips forward to lift your torso back to the starting position. This ensures you’re engaging your hip muscles instead of relying on your lower back. Do 10 reps total.
You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
