Straight leg raise: Lie on your back with your legs straight out in front of you. Bend the knee on your uninjured side and place the foot flat on the floor. Tighten the thigh muscle on your injured side and lift your leg about 8 inches off the floor. Keep your leg straight and your thigh muscle tight. Slowly lower your leg back down to the floor. Do 2 sets of 15.
You'll need a resistance band for this one. With this exercise you're focusing on four movements—flexion, extension, abduction and adduction. Try and stand up straight while doing the exercise. If you have to lean excessively, step closer to the anchor point of your band to decrease resistance. You'll find that not only are you working the muscles of the leg that's moving, the muscles of your stance leg will work quite hard stabilizing and balancing.
Relaxing in a full squat works for releasing the psoas if you’re comfortable. If you’re desperately trying not to fall over backwards, then you’re probably tightening your hip flexors to hold yourself up. This defeats the entire purpose of a resting squat. Grab something like a pillow or a couple books to throw under your heels and see if you can sink down and “rest” into a resting squat. Hold that for a little bit taking some really deep breaths directing the air and pressure of your breath into your back. Then stand up and move around. I bet your hip flexors will feel looser than before the resting squat.
The condition is cauda equina syndrome. It involves “acute loss of function of the neurologic elements (nerve roots) of the spinal canal below the termination (conus) of the spinal cord,” where the nerves spread out like a horse (equina) tail. Again, this condition causes symptoms in the “saddle” of the body: butt, groin, inner thighs. BACK TO TEXT
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.
