As you might imagine, the Hip Flexors are muscles that ‘flex’ your hips. Flexion of the hip is easy to understand. If you lay on your back and bring your knee to your chest, you are flexing your hip. Every time you walk, run, squat, jump, kick a ball, or do about anything that involves moving your thigh, you are putting your hip into at least some degree of flexion.
Although there are many muscles that are considered to be “flexors” of the hip, the two muscles that are most commonly thought of as ‘Hip Flexors’ are the Illicacus and Psoas (often referred to as one muscle — the Illiopsoas).
Although the Illiosposas is the muscle most commonly associated with the Hip Flexor family, it is certainly not the only one. Some of the most powerful muscles of the front thigh are considered to be Hip Flexors as well. These include the powerful Quadriceps Muscle (Rectus Femoris below), the Tensor Fascia Lata, and the IT Band (on the outside of the hip area), as well as the Sartorius.
As you are seeing, this is a common place to have problems. These problems include Fascial Adhesions, Tendinosis, and pulled muscles. To learn more about these problems as they relate specifically to Hip Flexor issues, HERE is the place to go.
