Good leg exercises you can do with a variety of equipment. The leg is divided into the upper leg (thigh) and lower leg (calf). The upper leg consist of one bone the femur, whereas the lower leg consist of two bones, the tibia (located on the big-toe side) and fibula (on the little-toe side).

The knee is a hinge joint formed at the junction between the femur and the tibia. Two movements occur at the knee joint: During the knee flexion, the lower leg bends toward the back of the thigh. During knee extension, the lower leg moves away from the thigh so the leg becomes straight. The hip is a ball-and-socket joint between the upper end of the femur and pelvic bone.
