|Utility:||Basic or Auxiliary|
Lay supine under fixed horizontal bar. Grasp bar with wide overhand grip. Straighten and raise body off of floor keeping heels on floor.
Pull body toward feet by bending knees and hips. Roll onto feet until knees are fully flexed. Return body to original position by extending knees and hips. Repeat.
Positioned bar so back is slightly above floor once grip is established. Keep low back straight, maintaining approximate height from floor throughout movement. Hamstrings seemingly acts as a dynamic stabilizer, since it shortens through knee, while it lengthens through hip. However, net contraction actually appears to occur, since hip flexes only slightly, while knee flexes nearly 100%, allowing hamstrings to remain in a mechanically strong position throughout movement. Dorsal flexion of ankle reduces active insufficiency of Gastrocnemius, allowing it to assist in knee flexion.
Movement can be made easier by positioning feet closer to bar.
Movement can be made more challenging by positioning feet further away from bar. Alternatively, hips can be kept straight during knee flexion increasing active insufficiency of hamstrings.
