Tight hip flexors can also make it harder for your glutes to activate—since they're opposing muscle groups, when one is really tight the other becomes lengthened. When a muscle is more lengthened than it should be, it takes away some of its ability to contract. When your glutes are in this compromised position, it can cause other muscles to do more work than they should, making your workouts less efficient and sometimes, increasing your risk of injury.
Hip flexor strains and injuries are often caused by “over doing it” (such as exercising) or periods of prolonged sitting combined with weak hip muscles. While hip flexor strains are typically not serious, they can be quite painful and severely limit your activity and mobility. Airrosti rapidly resolves most hip flexor injuries in as few as 3 visits — without the need for injections, medications, or long periods of rest.
The story of actor Andy Whitfield is a disturbing and educational example of a case that met these conditions — for sure the first two, and probably the third as well if we knew the details. Whitfield was the star of the hit TV show Spartacus (which is worthwhile, but rated very, very R17). The first sign of the cancer that killed him in 2011 was steadily worsening back pain. It’s always hard to diagnose a cancer that starts this way, but Whitfield was in the middle of intense physical training to look the part of history’s most famous gladiator. Back pain didn’t seem unusual at first, and some other symptoms may have been obscured. Weight loss could have even seemed like a training victory at first! It was many long months before he was diagnosed — not until the back pain was severe and constant. A scan finally revealed a large tumour pressing against his spine.
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.
