You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
In this study, one patient with sciatica was sent for ten MRIs, which produced 49 distinct “findings,” 16 of them unique, none of which occurred in all ten reports.

When was the last time you got on your gym's abductor or adductor machine and got in a good workout? It's probably been a while. Both are machines that don't get a lot of use, and they are often the target of coaches' ridicule on those "useless gym moves we should all skip" lists. Perhaps rightly so, especially if you're hopping on those machines hoping for a slimming effect.

A sedentary lifestyle can lead to having weak and tight hip flexors as they are always in the shortened position. Tight hip flexors can lead to a limited range of motion, poor posture, lower back and hip pain, and even injuries. These muscles need to get a workout when you are standing and doing movements such as raising your leg to climb stairs, run, or ride a bicycle.​
