4. Just swing it. For the front-to-back hip swing stretch, lie on the left side with hips stacked, propped up on the left elbow. Bend the left leg to a 90-degree angle and raise the right leg to hip level with toes pointed. Keep abs tight and swing the right leg all the way in front, then swing it all the way to the back, squeezing the booty along the way. Switch sides.
Correct posture and a protected spine requires strong muscles, and strong muscles require exercise. Rather than sit around waiting for lower back pain to fix itself, keeping active and exercising regularly can actually help it recover and stay in shape much more quickly. Not only that, regular exercise will help you lose weight which, in turn, will take pressure off your legs, hips, and back.
Luckily, you don’t have to quit your day job or forgo spin class to loosen them up. Simply stretching those hips can get your body back in alignment, increase your mobility (and thus your exercise performance) and maybe even ease pesky back pain, Moore says. “Given the amount of time we sit [each] day and the stress we put our bodies under, hip-opening moves are a necessary party of our daily routine.”

The hip rotators not only rotate the thigh on the pelvis but more functionally rotate the pelvis on the weight bearing fixed thigh. Activities such as swing a golf club, and even just walking require some rotation of the pelvis on the weight bearing leg.  While we don't need that much range of motion to walk, activities such as running, dancing, tennis, and many other sports can require more hip rotation.
While leg lifts, certain ab exercises, and even hula hooping can all help work the hips, the hip flexors can still be a tricky part of the body to stretch Kinetics of hula hooping: An inverse dynamics analysis.

To get them even stronger and more flexible, try these five simple hip flexor stretches:
Too much sitting is the enemy of stiff or achy hips, says Lisa Woods, a personal trainer and yoga teacher in Eagle, Colorado. The big problem, though, isn’t just the discomfort in the sides of your thighs. It’s the chain of pain that dysfunctional hips can create, including often-debilitating sciatic nerve pain that can start in your lower back and go down the backs of your legs.

How to: Sit down with your knees bent and feet flat on the floor in front of you (a). Place your right ankle on top of your left thigh and flex your right foot (b). Put your hands behind your body, fingertips facing away from your body and begin to press your hips toward your heels until you feel a stretch through your outer left hip. Keep your back tall and chest open (c). Hold for six to eight breaths, then repeat on the other side.
Located deep in the front of the hip and connecting the leg, pelvis, and abdomen, the hip flexors— surprise, surprise— flex the hip. But despite being some of the most powerful muscles in our bodies (with a clearly important role), it’s easy to neglect our poor hip flexors— often without even knowing it. It turns out just working at a desk all day (guilty!) can really weaken hip flexors since they tend to shorten up while in a seated position. This tightness disrupts good posture and is a common cause of lower back pain. Weakened hip flexors can also increase the risk of foot, ankle, and knee injuries (especially among runners) Hip muscle weakness and overuse injuries in recreational runners.

So be sure to get up, stand up every hour or so! And giving the hip flexors some extra attention is not just about injury prevention. Adding power to workouts, working toward greater flexibility, and getting speedier while running is also, as they say, all in the hips The effect of walking speed on muscle function and mechanical energetics.

Wow this is going to help me a ton! I was just thinking about how I wanted to work on my hips when I was on a 9 mile heavy pack hike yesterday. Even more so when I was done and one of my hips was/is pretty sore. Hips keep us together! Like for real they connect out lower and upper body lol. Need to make sure they are strong, mobile, and flexible which is all something I never really put any effort into improving. I figured my activities like Mountain Biking, Hiking, Climbing, Skiing, and doing squats/lunges along with other exercises would keep them strong. Then I come to find out I only was able to get through 2 rounds… This will now be apart of my training program 🙂 Thanks for the great video! Yes simple but yet it can kick your butt if you are doing proper form ad John Wolf stresses.
Why is back pain still a huge problem? Maybe this: “It is extremely difficult to alter the potentially disabling belief among the lay public that low back pain has a structural mechanical cause. An important reason for this is that this belief continues to be regularly reinforced by the conditions of care of a range of ‘hands-on’ providers, for whom idiosyncratic variations of that view are fundamental to their professional existence.”

You're more likely to get a hip flexor injury if you've had one in the past, you don't warm up properly before engaging in athletic activity, your muscles are already tight or stiff, or your muscles are weak from being overused. If, while exercising, you try to do too much at once in too short an amount of time, you can also put yourself at risk for a hip flexor injury.
