I think you should mention that for some people, stretching is not the solution and that it will deteriorate their posture. Some people need stretching, but most people I know need to strengthen their "overstretched" hip flexors. Many people can't do a single hanging leg raise.

Today I’m going to share with you one of my favorite hip flexor stretches. But first, you need to understand this isn’t a standalone fix for the problem. How to truly fix your tight hip flexors is really quite simple, but involves two steps: you need to fix your muscle imbalances and (probably) stretch out those hip flexors like I’m about to show you.
• Juvenile Spondylarthropathy. Also called juvenile-onset spondyloarthritis (spinal arthritis), this term is used to describe spondylarthropathies that begin before age 16. In addition to affecting the spine, they may cause pain and inflammation in the joints of the pelvis, hips, ankles and knees. They may also affect other body organs such as the eyes, skin and bowels.
• Rheumatoid arthritis. Rheumatoid arthritis is a chronic inflammatory disease of the joints that occurs when the body’s immune system – which normally protects us from infection – mistakenly attacks the synovium, the thin membrane that lines the joints. Although rheumatoid arthritis most commonly affects the hips, knees, hands, wrists, feet, elbows and ankles, it can also affect the facet joints in the spine, causing pain and, in severe cases, destruction of the joints. This may allow the upper vertebra to slide forward on top of the lower vertebra, a condition called spondylolisthesis. The slipped vertebra may put pressure on the spinal cord and/or the nerve roots where they exit the spine.
Kneel on your mat with your thighs perpendicular to the floor and tops of your feet facing down. 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 between your feet. Use your hands to turn the top of your thighs inward. Then, lean back onto your forearms and slowly lower torso to floor. Hold for at least 30 seconds.
If your sciatica is due to a herniated disk, and it's still causing severe pain after four to six weeks, surgery may be an option. The surgeon will remove a portion of the herniated disk to relieve the pressure on the sciatic nerve. About 90% of patients get relief from this type of surgery. Other surgical procedures can relieve sciatica caused by spinal stenosis.
Most back pain is harmless – caused by sleeping in an awkward position, stretched muscles, overexertion, sitting down too long or falling on the ischial tuberosity (the bones of the butt that you sit on), or minor hip injuries caused by twisting a certain way during sports like volleyball. Many injuries arise simply from improper form during exercise, sports injuries, or strains.
When lifting weights, it's important to find out how much weight is appropriate for you. Pariser recommends visiting your physical therapist to discuss how to safely lift weights without injuring your hip. “The lightest weight on the machines might be five or 10 pounds,” Pariser says. “That might be too hard for some people.” A good rule of thumb: Always use a weight that's light enough for you to lift comfortably.
The hip flexors are the group of muscles that allow you to lift your knees toward your chest and bend forward from the hips.  What is collectively referred to as the hip flexors is actually a group of muscles that includes the iliopsoas, the thigh muscles (rectus femoris, Sartorius and tensor fasciae latae), and the inner thigh muscles (adductor longus and brevis, pectineus and gracilis).
A basic bodyweight glute bridge is one of Lefkowith's favorites. Want to try it? Lie on the ground with your knees bent and your feet flat on the floor, and push your hips up toward the sky, squeezing your glutes at the top. This will not only help get your glutes in the game, but it also gives your hip flexors a chance to stretch out. (Try these five hip openers, too.)

To start, get into a lunge position with your right knee up and your left knee on the floor. Rest your hands on the ground, directly underneath your shoulders. Next, flex your raised right knee outward, so that you’re resting on the outside of your right foot. Press your chest forward to increase the stretch. Hold this pose for 10 seconds, then repeat on the other side of your body.

Grade II (moderate): A larger tear in your muscle that makes it difficult to move and causes a moderate amount of pain, especially when you move the affected muscle, swelling, and tenderness. You may have 5 percent to 50 percent loss of function and you may be limping. You can't go back to sporting activities until the tear is completely healed. These injuries can take anywhere from a couple weeks to a few months to heal, depending on how bad they are.
