In the front of your leg it is the quadriceps, in the back of leg it could be hamstring. There are two groups of muscles at the knee. The quadriceps muscle comprises four muscles on the front of the thigh that work to straighten the leg from a bent position. The hamstring muscles, which bend the leg at the knee, run along the back of the thigh from the hip to just below the knee.
The Iliopsoas actually consists of two muscles: the Iliacus and the Psoas Major. Together, they are known as the Iliopsoas.
The Iliacus originates on the pelvic crest and attaches on the femur.
The Psoas Major, the longer of the two muscles, originates on the lumbar vertebrae and attaches to the femur.
The Rectus Femoris is one of the four Quadriceps muscles and the only one that crosses the hip joint. This crossing of the hip joint enables it to operate as a hip flexor as well as a knee extensor (straightening the knee).
Overdeveloped and tight hip flexors can contribute to lower back pain by causing the pelvis to tilt forward. To counteract this, you must stretch the hip flexors and strengthen the Abdominal muscles. This will reduce decrease lower back pain. Strengthening the lower back can also help improve the balance between the muscles of the hip region.
