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.

Back pain can be confusing enough as it is. Sometimes it may be difficult deciphering if the pain is even coming from your back, and trying to figure out what causes it can be mind-boggling. And many experts recommend focusing on mechanical sources of your back pain rather than anatomical sources of your pain. Is it a herniated disc, bulging disc, or facet joint arthritis causing your problem? It can be hard to decide, so focusing on what you are doing and the positions you put your back in may be the best way to determine the cause of your back pain.

3. Tendinitis and bursitis Many tendons around the hip connect the muscles to the joint. These tendons can easily become inflamed if you overuse them or participate in strenuous activities. One of the most common causes of tendinitis at the hip joint, especially in runners, is iliotibial band syndrome — the iliotibial band is the thick span of tissue that runs from the outer rim of your pelvis to the outside of your knee.
If all you’ve been doing for your lower body lately is the occasional lunge, it’s time to mix up your routine. “Our bodies move in different directions, not in one direction, so it’s important to mimic that during cross-training,” Whitesides says. That’s why instead of relying on a pattern of “lunge-squat-repeat” — you might want to throw some plié squats, or leg lifts into the mix.
Exercise appears to be useful for preventing low back pain.[47] Exercise is also probably effective in preventing recurrences in those with pain that has lasted more than six weeks.[1][48] Medium-firm mattresses are more beneficial for chronic pain than firm mattresses.[49] There is little to no evidence that back belts are any more helpful in preventing low back pain than education about proper lifting techniques.[47][50] Shoe insoles do not help prevent low back pain.[47][51]
To avoid hip flexor pain, you should pay more attention to these muscles, Dr. Siegrist explains. When you are seated, your knees are bent and your hip muscles are flexed and often tighten up or become shortened. “Because we spend so much of our time in a seated position with the hip flexed, the hip flexor has the potential to shorten up. Then, when you are in a hurry because you are running to catch a bus or a plane, or you trip and fall, the muscle could become stretched. Here’s this stiff, brittle muscle that all of a sudden gets extended, and you could set yourself up for strain or some hip flexor pain.” Click Here to Learn Unlock Hip Flexors
