The lumbricals of the foot are a group of four small muscles located in the foot. They are located on the top of the foot, running from the metatarsal bones to the phalanges (the bones of the toes). The lumbricals of the foot are responsible for flexing the toes and helping to maintain the arch of the foot.

The lumbricals of the foot originate at the tendons of the extensor muscles in the leg, and insert at the base of the phalanges of the toes. They are part of a larger group of muscles known as the intrinsic muscles of the foot, which are responsible for the fine movements and stability of the foot.

In sports, the lumbricals of the foot are important for maintaining proper foot and toe position during activities such as running, jumping, and kicking. In daily life, they are used in activities such as walking, standing, and gripping objects with the toes.

To work the lumbricals of the foot, exercises such as toe flexion and toe spreads can be performed. These exercises involve moving the toes in different directions to strengthen the muscles of the foot.
