The muscles used in the leg press exercise are your Quads primarily. Hamstring gets a good work out too.
hamstring group
There are three main muscles of the posterior compartment of the thigh. They are the biceps Femoris , the semitendinosus and the semimembranosus. Together, they cause flexion of the knee and extension of the hip
The rectus femoris becomes active in a leg extension because one of the actions of the rectus femoris is hip extension, as well as knee extension. The rectus femoris crosses both the hip and knee on the anterior side of the body. When the leg is extended it is one of the primary movers, whether it be straight leg extension, in which case it is the rectus femoris, illium and psoas muscles. In knee extension the rectus femoris works in conjunction with the other 3 quadriceps. However, in the case of a seated leg extension the rectus femois is less active, due to it already being shortened for the hip extension.
hip extensor, gluteus maximus
The quadriceps perform knee extension, however, the rectus femoris, which is one of the 4 muscles of the quadriceps, also does hip flexion.
Vertebral Foraminal Entrapment on Hip Flexion and Knee Extension
The purpose of the gluteus maximus is extension, including hyperextension, of the hip.
Muscles within the brachium are responsible for the extension of the elbow. These muscles also work for the flexing of the arm as well.
Flexibility is measured by the range of motion. The range of movement is measured by using a goniometer: hip flexion, hip extension, hip adbuction, hip adduction, shoulder adduction, shoulder fexion, shoulder extension, elbow flexion/extension, and knee flexion/extension.mile run
