This large angle significantly stretches, and thus demonstrates excellent flexibility of, the hamstring and iliopsoas muscles. Consequently, splits are often used as a stretching exercise to warm up and enhance the flexibility of leg muscles. A split that goes beyond 180° is called an oversplit.
The iliacus and nearby muscles. The hip flexors are (in descending order of importance to the action of flexing the hip joint): [2] Collectively known as the iliopsoas or inner hip muscles: Psoas major; Iliacus muscle; Anterior compartment of thigh. Rectus femoris (part of the quadriceps muscle group) Sartorius; One of the gluteal muscles ...
In open-chain exercises, as part of the iliopsoas, the iliacus is important for lifting (flexing) the femur forward (e.g. front scale).In closed-chain exercises, the iliopsoas bends the trunk forward and can lift the trunk from a lying posture (e.g. sit-ups, back scale) because the psoas major crosses several vertebral joints and the sacroiliac joint.
The psoas major unites with the iliacus at the level of the inguinal ligament. It crosses the hip joint to insert on the lesser trochanter of the femur. [1] The iliopsoas is classified as an "anterior hip muscle" or "inner hip muscle". [2] The psoas minor does contribute to the iliopsoas muscle. The inferior portion below the inguinal ligament ...
Anteromedially and inferiorly to the AIIS is the iliopsoas groove, the passage for the iliopsoas muscle as it passes down to the lesser trochanter of the femur. A vague line, the inferior gluteal line, might run from the AIIS to the greater sciatic notch which delineates the inferior extent of the origin of gluteus minimus muscle. [1]

Tightness of the psoas can result in spasms or lower-back pain by compressing the lumbar discs. [9] A hypertonic and inflamed psoas can lead to irritation and entrapment of the ilioinguinal and the iliohypogastric nerves, resulting in a sensation of heat or water running down the front of the thigh. Psoas can be palpated with active flexion of ...
The deadlift is a very effective compound exercise for strengthening the lower back, but also exercises many other major muscle groups, including quads, hamstrings and abdominals. It is a challenging exercise, as poor form or execution can cause serious injury. [8]
