Erector Spinae The Erector Spinae muscles run all the way up each side of the spine from the base of the sacrum to a portion of the muscles attaching at the base on each side of the skull. The fibres are divided further into three sets...
Biceps Femoris The ‘Hamstring’ muscle group is made up of three posterior thigh muscles. The Biceps Femoris is positioned as the lateral muscle of the hamstrings and is the only muscle of the group to have two heads. This muscle suffers from...
Semimembranosus The ‘Hamstring’ muscle group is made up of three posterior thigh muscles. The Semimembranosus is positioned as the deep and medial muscle and is the largest of the group. This muscle suffers from tears and ruptures often due to...
Semitendinosus The ‘Hamstring’ muscle group is made up of three posterior thigh muscles. The Semitendinosus is positioned as the superficial and medial of the group. This muscle suffers from tears and ruptures often due to inadequate stretching...
Iliopsoas The Iliopsoas muscle group is formed by two muscles that blend into one; the Iliacus and the Psoas Major (the Psoas Minor is only occasionally present). The Iliopsoas is the primary muscle involved in hip flexion. Tightness...
