The gluteal muscles include the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae.They cover the lateral surface of the ilium.The gluteus maximus, which forms most of the muscle of the buttocks, originates primarily on the ilium and sacrum and inserts on the gluteal tuberosity of the femur as well as the iliotibial tract, a tract of strong fibrous tissue that runs ...
The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint. It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus. [1]
Kipping pull-ups have lower muscle activation in the upper body but greater activation in the lower body and core; it is possible to perform them faster and complete more repetitions before encountering upper-body fatigue. [14] Kipping pull-ups are considered high risk for injury and are a major cause of shoulder injury in CrossFit athletes. [15]
Yet just because women tend to have less muscle strength in their upper extremities — making pull-ups a challenge — doesn’t mean that they have to miss out on all of the benefits a pull-up ...
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 ...
The gluteus maximus is the main extensor muscle of the hip in humans. It is the largest and outermost of the three gluteal muscles and makes up a large part of the shape and appearance of each side of the hips. It is the single largest muscle in the human body. [1] Its thick fleshy mass, in a quadrilateral shape, forms the prominence of the ...
The chest fly is performed while lying face up on a bench or standing up, with arms outspread holding weights, by bringing the arms together above the chest. This is a compound exercise for the pectorals. Other muscles worked include deltoids, triceps, and forearms. Equipment: dumbbells, cable machine or "pec deck" machine.
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.
