• Osteoporosis. Osteoporosis is a condition in which the bones loose so much mass that they become brittle and prone to break with slight trauma. The condition, which can occur with aging, inactivity, a low-calcium diet or use of corticosteroid medications, commonly affects the spine. When this occurs in the spine, the inner spongy bone and more solid outer portion of the vertebrae become porous. The weakened vertebrae can break – an injury called a compression fracture – and lose about one-half of their height. In most cases, compression fractures, are painful. In some cases, the resulting back pain is severe. Usually, the pain resolves within a few weeks, but for some people, it is long-lasting.
However, runners are infamous for imbalances in their hip muscles. The most common weak ones are the hip abductors, the muscles on the side of your butt responsible for moving your leg out away from your body to the side. Lev Kalika, D.C., clinical director of New York Dynamic Neuromuscular Rehabilitation & Physical Therapy, tells SELF that since most runners run, run, and only run, they are constantly training their hip flexors and extensors through a very small range of motion. That can lead the hips to be unstable on the less-frequent occasions when you bring your knee all the way to your chest or thrust your hips forward.
In addition to these exercises, there are simple things you can do every day to help reduce your risk of hip flexor pain.  If you sit at a desk for long periods of time, try to get up and move around every hour or so.  Warm up properly before any physical activity, and stretch regularly at the end of each workout.  Your hips will thank you for it! 

You’d think so. But consider this story of a motorcycle accident: many years ago, a friend hit a car that had pulled out from a side street. He flew over the car & landed on his head. Bystanders showed their ignorance of spinal fracture by, yikes, carelessly moving him. In fact, his thoracic spine was significantly fractured … yet the hospital actually refused to do an X-ray because he had no obvious symptoms of a spinal fracture. Incredible! The next day, a horrified orthopedic surgeon ordered an X-ray immediately, confirming the fracture & quite possibly saved him from paralysis.
Now, that we have decreased some of the tension in the back, we can focus on strengthening the front. There are loads of awesome core exercises, but let’s take a look at the most common one and make a couple modifications for this postpartum population. Just keep in mind, these are things to look for in a woman that’s 8 weeks or 8 years postpartum. Just because it’s years later doesn’t mean she fully recovered.
Back “spasms” are a largely a myth — there’s no such thing a sustained painful contractions of muscles in otherwise healthy people (see Cramps, Spasms, Tremors & Twitches) — but the kernel of truth in the idea of “spasms” may be the idea of trigger points, which are hypothetical “micro cramps,” tiny patches of painfully contracting muscle. Although this idea is controversial, it is nevertheless one of the most likely explanations for common aches and pains that mostly stick to one area (especially the back) and have no other obvious cause.

These are large, full-range movements of one or more joints at once, often performed standing and sometimes while walking or jogging. They resemble old-school movements you might have done in calisthenics or gym class: arm swings, leg swings, high-knee walks. You usually count off reps, rather than time, on dynamic stretches, which work best as a warm-up activity before a workout, or any time you need a pick-me-up boost throughout the day.
The sciatic nerve is the largest and longest nerve in the body. It arises from the spinal cord as a collection of fibers from the lower vertebrae. This nerve is responsible for the sensation of the skin of the foot and entire lower leg except for a small area on the inner side. It also supplies muscles in the anterior, lateral and posterior compartments of the leg.
When I do a deep knee bend like a sumo squat I get a popping in the outside of my left knee. It feels like a big tendon or ligament is slipping per something. It isn’t painful peer se but I’m afraid if I do it a lot it will be. Is that a relatively common symptom for a guy with tight flexors, it bands, etc? Should I just push through it or have it checked out?
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.
How to do it: Rest the barbell across the upper traps on the back of your shoulders, as if it’s sitting on the collar of your shirt. Begin with your feet about shoulder-width apart, toes pointing about 15 degrees out, then widen your stance as needed so you’re comfortable. Make sure your knees are pushed out and your glutes stabilize your position. When you’re ready, push your glutes back as if you’re sitting in a chair. Aim for dipping your butt below your knees, but go down as far as you can without bending forward or losing balance. When you get the bottom of your squat, squeeze your glutes and drive up and through your heels back to start position.

Here is how you do the hip rotation stretch: Sit on the floor with your knee out straight. Cross one leg over the other by placing your ankle on top of your knee (as if crossing your legs while sitting). Gently pull your knee across your body, and hold for five seconds. Then gently push the knee of the top leg away from you until a stretch is felt in your hip. Hold this position for five seconds, then slowly release. Repeat 10 times.
Kneel on your mat with thighs perpendicular to the floor and tops of of your feet facing down. Place a yoga block between your feet. Bring your inner knees together. Slide your feet apart so they are slightly wider than your hips, and press the tops of your feet evenly into the mat. Slowly sit down on the yoga block. Use your hands to turn the top of your thighs inward. Allow the backs of your hands to rest on your thighs. Hold for at least 30 seconds.
Please note that none of the above given tips or recommendations substitute medical advice. Important: consult a health professional in case of an injury or if you suspect overuse of joints or a medical condition such as a fracture. A physician should be consulted in those acute cases when the condition is accompanied by reddening, swelling or hyperthermia of joints, ongoing joint trouble or severe pain and/or are associated with neurological symptoms

The main work of your hip flexors is to bring your knee toward your chest and to bend at the waist. Symptoms associated with a hip flexor strain can range from mild to severe and can impact your mobility. If you don’t rest and seek treatment, your hip flexor strain symptoms could get worse. But there are many at-home activities and remedies that can help reduce hip flexor strain symptoms.
